Among the biggest developments since I last reviewed these apps: Apple released the iPhone 4, with its faster processor and higher-resolution display; Apple released iOS 4, which offers background location updates for navigation programs; AT&T started metering cellular data usage for all new accounts; and Apple released the 3G iPad, which includes its own GPS receiver.
The app developers have been busy, too. Most apps have gone through substantial revisions and improvements, with notable fixes to iPod music control, performance, and address recognition. Still, some basic problems in user interface and finding addresses remain. A few apps haven’t been updated in several months or longer, lacking full iOS compatibility and support. Others retain clunky interfaces borrowed from standalone GPS hardware with vastly less capability than iOS devices.
In this round-up, we revisit 11 apps (dropping one that’s no longer available for sale). Testing was done in and around Seattle, Washington.
[Editor's note: We didn't test Garmin StreetPilot, which was released in early January, but will add it to a follow-up review.]
11 iPhone GPS apps reviewed
Price listed is for lowest-cost version that offers maps of entire U.S.
*GoKivo includes 30 days of voice-guided turn-by-turn navigation at no cost. In-app purchases of 30 days ($5) or 1 year($33) are available. Without an active in-app purchase, the application provides maps and POI data only, not navigation (with or without a voice). **MotionX (regular and HD) includes 30 days of voice and automatic turn-by-turn navigation in the $1 purchase price. In-app purchases of 30 days ($3) or 1 year ($25) are available. Without an active in-app purchase, the application provides manual turn-by-turn navigation like the Maps app, and other map features. †amAze GPS is free to download, but requires $34 per year purchase for activation. ††CoPilot’s $5 price tag includes unlimited navigation use, but TTS is an extra, one-time in-app purchase ($3). A free over the air version includes 30 days of free voice navigation.
The iOS 4 factor
iOS 4 brought many changes, like folders for organizing apps and an app bar that can be popped up for switching. But the big changes for navigation software are background location updates and fast-app switching.
Background updates allow navigation apps to receive a stream of live GPS coordinates even though the software obviously can’t show such updates on a map. You can tell that background location updates are happening, even without voice or text prompts, if you see the location arrow in the upper right corner of the iPhone’s display.
Fast-app switching can be used by developers to resume an app from where you left off. In the case of navigation apps, fast-app switching nearly immediately displays your current location on a map when you resume.
With a route underway in an app, directions appear in one of two ways when you exit the navigation program. If you answer an incoming phone call or switch to place a call, iOS 4 savvy apps will use text notifications for directions. Because these notifications need to be dismissed, it could be a distraction on top of the phone call. If you switch to another app, the navigation program will continue to offer spoken directions. (Some apps let you modify those default behaviors, too.)
You can’t force iOS 4 to keep a program running after that app has been switched into the background. If you swap among enough apps, it’s possible your navigation app will be purged to free up memory, although in my testing it seemed to be the case that programs with active background operations are ranked higher in the priority list.
Using GPS navigation uses massive amounts of power, and that’s true even if your navigation app is running in the background. Because you could be listening to audio (also available in the background), running navigation, and using other programs, your battery can drain very quickly unless it’s plugged into a car charger. (You might consider focusing on driving.)
Because these apps can now run in the background, being able to cancel out of navigation mode when you’re done using them is essential—just pressing the home button won’t do the job. Several nav apps make it simple to cancel a route before exiting. Navigon MobileNavigator and AT&T Navigator, have a button on the navigation screen you tap to cancel or stop routing. Other apps nest such a button one level deep. However, a few apps haven’t yet been revised to make this simpler. TomTom requires tapping three levels down to clear a route, for instance.
Some programs lack any obvious way to purge a route. In those extreme cases, you must force-quit the app by switching to another app or going to the home screen, double-tapping on the home button, and holding your finger down on the nav app in question until an x in a circle appears in the app icon’s upper-right corner; tap that to kill it off, free up memory, and preserve your battery life.
You need iOS 4 installed on an iPhone 3GS or 4 to take advantage of background navigation. The iPhone 3G has a GPS chip, but lacks the specs to run background tasks. The iPad update to iOS 4.2 lets those devices work with location in the background, too, but only the 3G model has a GPS receiver; the Wi-Fi-only iPad isn’t capable.
Only GoKivo (last updated Nov. 2009) and G-Map (last updated Feb. 2010) lack fast-app switching and background navigation. We cannot recommend such programs because they require that you change the way you have likely gotten used to using your iPhone in iOS 4, when you don’t need to make that compromise. Most apps have a lot of room for improvement for an easy (but not accidental) way to cancel a route before switching out.
iPad navigation
MotionX HD offers jumbo navigation for iPad 3G users.
GPS apps otherwise generally work on the 3G iPad in the iPhone/iPod touch compatibility mode in which apps are centered in the middle of the screen, but can be pixel doubled (blurring graphics) by tapping the 2x button.
Get accessorized
You could just download a GPS app from the App Store and hit the road. But to take full advantage of using the iPhone as a navigational aid, you’ll need two key accessories.
Charging cable. Using the GPS sucks power like nobody’s business, draining a full battery in a couple of hours. You will want a car-power adapter, likely one that also provides audio output; or if your car stereo lacks iPod integration with USB charging, you may want to upgrade to a model that supports that. If you use an integrated iPod stereo, consider which apps talk over music and which pause playback.
Windshield mount. Oh, yes, you will want some kind of mount. It’s critical that the iPhone has a line of sight as good as possible to the sky, and resting your iPhone somewhere or hoping it works in the passenger seat isn’t a real option for regular navigation use. I recommend the Kensington windshield mount, which has a long positionable arm, making it possible to move the phone to a better viewing angle that was more reachable when stopped at traffic lights or pulled over. The arm can vibrate while driving. (Kensington Windshield Mount for iPod and iPhone, $25.)
Two kinds of apps
The 11 iPhone GPS apps I tested can be split into two categories: apps that come with bundled maps and cost from $5 to $50, and apps that download map data only when necessary, and generally charge a monthly or annual subscription fee. CoPilot offers both options as separate apps. (For a complete list of the apps I tested, see the table “iPhone Navigation apps,” above.)
AT&T Navigator (left) and Navigon MobileNavigator (right).
We tested the United States versions of apps, where available; U.S./Canada combos or North American editions are typically $10 more. In the last year, several apps added U.S.-only versions. Most navigation app makers have separate packages customized by country and land mass with a different price for each.
Among subscription-based apps, only AT&T Navigator is attached to a single phone number; ALK Technologies’ CoPilot requires separate registration and serial number entry with the program; and MotionX keeps track of your voice-navigation subscription, allowing it to be used on one device at a time. All the other products I tested can be installed on any iPhone OS device that’s attached to your iTunes ID—meaning a family that syncs with one account and multiple iPhones and 3G iPads can buy the apps once and use them on all their devices.
Eight of the apps we reviewed charge one-time flat fees and include some promises about additional releases with upgraded maps. Last year, I had hoped the upgrade situation would be clearer in 2010. Guess what? It’s not. In the last year nearly every program has been updated every few weeks to months with bug fixes, new features, and updated maps. (Copilot offers multiple versions of its software for the U.S. and North America, including apps with internal maps and over-the-air live retrievals. We reviewed its flat-fee U.S. version.)
We suspect that navigation apps will eventually become yearly editions that continue to work in subsequent years without support or further updates. Developers might also switch to in-app fees for map updates downloaded directly into the program. (Standalone GPS devices can levy $40 to $100 per year fees for map updates, so this isn’t unprecedented.)
Flat-fee packages are huge downloads incorporating the full map database with the program file. The ones we tested range from 1.2 GB to 1.8 GB. This has the advantage that full maps are always with you, even away from cellular coverage areas, and you don’t use up cellular data downloading map data.
Every time there’s a new version of the app, however, you’ll need to download the entire file—with the exception of CoPilot, which has an internal update function, and TomTom, which recently added a way to integrate small updates. You should download full app updates via iTunes and sync them to your iPhone or iPad. Even though you can download such updates over Wi-Fi, I’ve found Wi-Fi updating unreliable for such large apps.
On-the-fly map programs download some data when they plot routes, and cache a subset of the information needed to create 2D and 3D maps. MotionX lets you simulate the route, which it can zoom through at up to eight times normal driving, and cache mapping data as it goes. But the company recommends using this at only 2x speed, which seems a bit ridiculous for a long route.
MotionX can cache up to 2 GB of data, the quantity of which is a user setting. It’s not clear how or if it ages out over time, but you can manually purge the cache. Other apps don’t expose how they cache and age out map and route data.
If you stray outside the planned area over-the-air apps need to access the network for new information or re-routing. You also need to be on a network when plotting a route, looking for detours, or having traffic information update with software that offers that option.
All these map, traffic, and route downloads create a problem if your network plan limits data and charges for overages, as do all AT&T plans for new customers starting in June 2010, or for existing customer who downgrade plans to save money. (Carriers outside the U.S. either limit usage and charge overage fees, or cap usage at a certain limit with a billing cycle, and then reduce network speeds to 64 Kbps for the remainder of the month.)
You might want to track your cellular data usage, too, as over-the-air GPS programs will download as much data as they need while you’re navigating your path. While this is a small amount of vector and descriptive data per screen, some apps include rudimentary 3D building models or outlines, and you’re downloading over the course of however long your drive is.
The recurring in-app or out-of-app subscription fee for over-the-air apps may turn some people off. On the flip side, you can pay for a month of service to test it out before committing to a non-refundable $15 to $50 fee. The one exception here is MapQuest 4 Mobile, which is entirely free to download and use. It ties in with MapQuest and Yahoo’s local advertising services, which explains the lack of a fee. The service works quite well, although it lacks some features frequent travelers will require.
AT&T’s app, a free download, has the highest subscription price of the five live-download apps, but in my testing it was worth the money. Using AT&T’s free MyWireless app, you can turn service on or off for a month at a time. The $10-per-month fee is fine for occasional use, given the high quality of the app and its traffic data. You can also subscribe to AT&T Navigator for a full year for $70, comparable to the cost of flat-fee apps when traffic fees and map updates are figured in. (AT&T doesn’t pro-rate the yearly price; cancellation is possible only within the first 30 days.)
MotionX ($1) and GoKivo (free) include an initial 30 days of navigation services after installation and activation. MotionX charges $3 for 30 days or $25 a year for automatic turn-by-turn directions. GoKivo is $5 for 30 days or $33 for a year for navigation.
Entering addresses
Sygic's app failed to find addresses reliably.
One of the keenest places to find whether an app understands iOS and its users’ expectations is in entering a destination address. Last year, it was more reasonable that some apps didn’t offer perfect address handling, whether using the built-in Contacts list or in entering locations by hand. Some European companies clearly didn’t understand U.S. address formats, too.
However, a year later, it’s pretty much unforgivable if a standard North American address is rejected or can’t be recognized. And, unfortunately, I found that many poor performers last year in dealing with addresses remained poor this year. Honestly, how hard is it to strip “#102”, “Apt. 53A”, or “Suite 207” from an address? Several apps can, making it even more glaring in those that can’t.
Sygic is the worst offender, especially after the low rating awarded by Macworld last year, and correspondence I had with the company providing addresses to test. Sygic did not recognize this was a flaw in the program. Dozens of addresses from my Contacts list failed last year; this year, only Apple’s succeeded—and then because the program ignored the “1” in “1 Infinite Loop.” The app also loads addresses slowly into a list; all other apps tested that use Contacts pop them up instantly. (I retested after the company released version 8.2 in December, which promised better address recognition. The same problems persisted.)
With other apps, I tested a dozen or more routine addresses from my Contacts list, as well as some particularly difficult ones, such as a fire road in a small town in Maine. AT&T remains at the top of the list, plotting every addresses attempted, and resolving locations even better than the Maps app. MapQuest was just a step or two behind, recognizing almost all addresses, and providing a popup suggestion for those it couldn’t that were all correct or extremely close to the destination. MotionX is also quite good.
TomTom had the greatest improvement. Last year, the program could match more than half the addresses I tested; this year, it found all. The two it could not, it offered step-by-step searches to resolve its confusion, leading to the correct location. CoPilot also improved, and offered a similar guided process for addresses it cannot recognize, but half the addresses tested needed more help or couldn’t be matched. GoKivo also made great strides, missing only a couple of obscure addresses, although it placed my Seattle office in North Dakota.
iGO My way perversely performed worse, sometimes with the same addresses, matching less than a third of those tested. It showed an unhelpful “No usable address found” error with no guidance. G-Map, RoadMate, MobileNavigator, and CoPilot continue to miss about half of dozens of addresses tried, and need improvement.
All apps provide you with multiple ways to select a destination, typically including from a map, by entering a street address or intersection, or searching on a business name or person’s name. In some cases, entering addresses is tedious, though, requiring the selection of a country, then state, then city, then street name, then house or building number. CoPilot Live failed to allow entry of a common street in Seattle.
TomTom’s new “navigate to a photo” option had me thinking at first the company was cross-referencing with Google’s Street View using image recognition, but it’s nothing that computationally crazy. You pick a photo taken on your iPhone that has embedded location information—available unless you’ve disabled that option—and it pulls up the coordinates.
AT&T Navigator added the option of voice recognition by calling a California phone number, which connects you to an automatic system. In testing, my dad’s address in a small Washington town couldn’t be recognized by voice (AT&T insisted that N. Victory Ave was N. Geary Ave), although it was available on a map; other addresses worked just fine.
On the road
Once you tap Go or Navigate or Drive to start the navigation process, you may find different features en route to have different levels of utility to you. Sometimes, this may vary by the trip you take.
Traffic Eight of the eleven apps offer the option to show traffic alerts and use traffic information for route planning and rerouting. Drivers who travel extensively in urban areas will find traffic data a necessity. AT&T, GoKivo, and MotionX include traffic as part of the subscription price for their live services, while MapQuest and Magellan offer it at no cost. CoPilot, G-Map, and TomTom charge yearly subscription fees. Navigon MobileNavigator offers it as a one-time in-app purchase.
Lanes and indicators Each package approaches what it shows on screen in different ways. While all (except MapQuest) show or offer a 3D view, you can typically set what kinds of additional information is shown: current speed, maximum speed (where known), estimated time and distance to arrival, and so forth. The best of the navigation software shows a popup lane position, identifying which of multiple lanes you need to be in to either make an exit or avoid being forced off on an exit. Some software also pops up simulated street signs, much like highway signs, to offer more cues for which exit or direction to take. The weakest apps in this area have improved, and there’s no specific advantage—only differences—among the reviewed apps.
Spoken streets All reviewed apps now include text-to-speech (TTS), in which street names and other landscape, direction, or road features are spoken in addition to distances until a turn or change. TTS has generally improved since 2009, when a few voices were unacceptably rough.
However, well-known place names should also be called out and corrected over time. In Southern Calfornia a few months ago, I heard TomTom’s software flabbergastingly say, “Turn right to enter Loss An-guh-less.” iGo myWay can’t say the word takes a hybrid approach, offering a selection between a more natural-sounding voice and a TTS voice. The natural voice only provides spoken names about 40 percent of the time when it thinks it can synthesize them well using rules it’s defined; the TTS voice is perfectly fine, but speaks all names. (The TTS voice is a 55MB download within the app.)
Macworld’s buying advice
Many GPS apps have improved noticeably over the past year, leading me to promote them to four-mouse ratings. AT&T boosted itself even more strongly with subtle and obvious improvements, and its continued superb recognition of addresses in Contacts. While the fee may seem high, it’s hard to beat for accuracy, traffic integration, and good directions. MapQuest, at no cost, is an extremely solid second choice for over-the-air apps.
If you want to store maps on your device and not rely on cellular access for navigation, TomTom and MobileNavigator now tie for first place. Both need modest improvements, but you’ll be happy with either. Their price, at this writing, is identical for U.S. editions.
The most important part of a GPS app is that it’s just a tool that should easily get you safely and reliably between any two points you specify. In my testing, no program reviewed failed to deliver on that promise, but the combination of ease of use and the specific features each firm put into their software should help steer you—pun intended—to the right app for your needs.
