Yes, this is it: I dont need - and I dont want - my Garmin handheld GPS anymore. This app does it all, and it does it even better than every handheld GPS Ive tried before (the interface is so much more intuitive and user-friendly).
I use the app mostly for hiking / trekking / snowshoeing trips, and its perfect (you can download the maps you need before you leave, so you can use the app while you are out there and offline - dont even need cell network nor wifi). But I could also use it for biking trips, and I believe it would work just as fine.
Ive been testing it in Canada (mostly Québec) and in Northeastern US for a while now, and it has been working like a charm (I really dont understand the comments saying its "useless in Canada" - just learn to use it, and it will become usefull, youll see, its very easy, much easier to learn than most handheld GPS units with their weird and toyish interfaces). I also started to plan a trekking trip to North Africa / Europe with the app, and the maps are very accurate (you can use many different maps, but I mostly use OpenCycle topo map, which is great and much more accurate than the Garmin Topo for which you have to pay $150 or so – crazy! –, and you can even find trails and small dirt roads in the North African backcountry desert!!). You can see that map on OpenCycle website to get an idea.
I did subscribe to Gaia PRO (free trial), and the app gets even more interesting, with satellite imagery (that you can also download and use offline!) and many other map sources. I really think both the app and the Gaia Pro subscription are worth every penny youll spend on them (but no, you don’t need the Gaia Pro subscription at all to fully enjoy the app).
The only thing I didnt like at the beginning (and still don’t like, to be honest) is that you have to pay – get a Gaia Pro subscription – to be able to plan routes on GaiaGPS.com (the website / cloud, which is the "Bandcamp" of GaiaGPS, sort of) and then sync them into the app. For now, if you dont subscribe to Gaia Pro, you can only plan routes right in the iOS app, which is ok (its easy, sure), but it can be a real pain when you have a lot of planning to do (you have to spend hours in front of you little iPhone screen). To me, this route planning feature on the website is a very basic GPS use that should be free and open to everyone who paid $20 for the app. I also believe its the only reason why you might still want / need to use another software or website with this app, if you dont want to pay for a Gaia Pro subscription (you can plan your routes on the external software or website, and then import them in GaiaGPS app; its really easy).
And sure, there are still a few things that could be improved. For instance, I would really like to have a "track recording interval option" (which you can find on many – most? all? – handheld GPS units). This would really help to save iPhone battery, and would be extremely useful for those who do extended backcountry trips without any access to power sources for many days / weeks, but who still want to track their trips. Its almost impossible to do right now, even with an external battery pack (the GPS tracking mode kills the battery way too fast – 7-8 hours or so with an iPhone 5, with everything else turned off). But this is the same on most GPS apps, I have to say, and maybe it’s also an iOS limitation.
But these are really details, and overall, GaiaGPS is already a state-of-the-art GPS app. And I also understand it keeps improving very fast. The new uptdate (9.2) – which was the first update since I bought the app – really does improve several things (among others, it has a new and more intuitive Trip Computer to record your tracks). And there’s also a fairly big community of users who share their ideas on the feedback page to enhance the app.
I have to say I usually dont write reviews (and no, I don’t know the GaiaGPS people). But seriously, this app is really (one of) the best thing that happened to my iPhone ever: it turned it into a awesome handheld GPS unit – with satellite imagery! – that I can use for all my backcountry and hiking trips. So I really wanted to take some time to share the good news and thank the GaiaGPS developers. And well, Im saying I don’t know the GaiaGPS people, but I don’t think I should really say that: I had to contact them at the beginning to get support with some features, and they were super-fast and super-friendly and super-helpful answering all my questions. I felt right away they were friends! (Thanks Josh!)
So if youre looking for a GPS app for outdoors – hiking, backpacking, trekking, snowshoeing, biking... name it –, I really recommend you this GaiaGPS app. I tried a few others before – yes, Motion X is one of them –, but in my opinion, you just cant even compare, Gaia is the best all the way, and you’ll really get what you pay for. And if youre still not sure (like I certainly was before I bought it, a couple months ago), have a look on the website before, it will give you a much better idea of the app and how you can use it. And then, you’ll probably say "Goodbye Garmin" like I did a while ago...
