Built only from these 120 real reviews (foreign ones translated). Superscripts jump to the quote here. Apple has no per-review links, so [ref] opens that app's reviews on the App Store.
- [R2] Amazing App: Made by the same creators of Hiking Project, this is an amazing app. No big companies asking for their $30 premium for the most basic of features. No ads, only just pure trails and community help. Please let me marry these developers.
- [R13] Complete package.: Love the app. As good or better than other trail apps.
- [R81] Incredible resource to find trails wherever you are: Search with the map feature, dig deeper with reviews, difficulty ratings, and elevation profiles. So useful for discovering and planning rides. And then link to maps for directions to trailhead. Excellent app, full featured and easy to use.
- [R1] Unstable: Crashes often, UI is hideous and text runs into graphic blocks. Borderline unusable.
- [R5] Nothing but crashes: Used the app for years with no issue, but using it with low service now and it continuously crashes. Very disappointing and makes the app completely unusable. Also please update your UI for Liquid Glass, the app looks terrible
- [R24] Crashes ALL THE TIME: There are no words for how much rage this app gives me now. It crashes constantly. I’ve been using it for 4 years and have never had this problem. Whoever made these unstable changes should be fired immediately. I look forward to someone duplicating this exact app but without the crashing. I will switch in a heartbeat
- [R57] Rating the app experience (CRASHES!): First off, I love mountain bike project as a concept and used and contributed to mountain project back in the early years. However, as a fellow app developer, MTBP is inexcusably crash-prone. Don’t have good service? Crash. Don’t have service and want to move around on the map? Crash. Zoom out too fast? Crash. Want to view the whole enchilada or any other 20
- [R3] Removal of GPX files and other issues: The app doesn’t make it easy to reset your password. Also there are no longer GPX options to download to a Garmin.
- [R14] Keeps crashing: maps keep crashing on iphone when you try to zoom in or out.
- [R30] Crashes when you need it most!: It’s crashed several times, always when I’m at some crucial intersection…
- [R44] Crashes so much its unusable: in current form can't recommend, used to be a great resource but now it crashes every time I try to pan around the map making it totally unusable. Will change back to 5 stars when fixed!
- [R12] Great app, needs some love: This is definitely the best app for mountain biking, but I wish OnX would put a little effort into making sure it doesn’t crash, and add a feature to sort/filter by condition status.
- [R46] Best MTB app around.: My favorite MtB app. I wish more folks used it and kept trail pictures and conditions current. I’ll do my part!
- [R139] Impressed: So much improvement from about 5 yrs ago! MTB Project is now my go to - i'll never use trailforks again!!! Project is excellent - Thank you for continuing to improve 🙏
- [R87] Good app, bad user interface: Good app, but the requirement for an account to do half the functions is a little ridiculous. For example, you can’t even mark a trail as a favorite without logging in. And some of the UI choices are just plain bad - e.g., the button to “update” a place is right next to the “go to” and “delete” buttons, and all three of them have such tiny text it’s easy to click the
- [R226] Really poor interface: Really bad interface.. was having issues route finding because the map wouldn’t let me move it around while it was recording. Not to mention, the recording feature is way off in stats. Doesn’t match up to the trail and for some reason won’t let me go back and review anything about it. I had high hopes because it seemed like an all trails for bikes, but turned out to be very
- [R127] AWESOME: This app is free which is a bonus. You can add trails that aren’t on here and you can rate trails. It has lots of descriptions of the trails such as what rating it is, from easy to double black diamond (which you can rate too you just need an account), and star ratings from 1 star to 5 stars (which you can also do with an account). There are also NO ADS which is great. You can also recor
