5 stars: Great app to keep track of your mileage. I've been using this app for mountain biking and road cycling. You can change the activity and the app will adjust. What I also enjoy about this app, it keeps track your your route; top speed, average speed, elevation change and calories burned. App works great. I have not had any problems with it so far.
3 stars: Unfortunately the timer is not accurate at all. I have had times where it stops when it shouldn't, and vice Versa. Its unfortunate, as this App jadd the potential to kick ass!!! Update: I just downloaded the upgraded version, and will change my opinion if it improves.
5 stars: been using this app for years to track my rides, pretty accurate on the paved city miles.... on the Switchbacks trailrides it's not as accurate but not many are because of the quick turns so that's an all-around issue with all similar apps....but not really an issue for me....great experience so far
3 stars: I've downgraded my rating as frequently app is not tracking my route. It never used to be a problem, but have just seen app was upgraded in May which is when the problems started.
3 stars: If you want exact split times and distances for your rides then don't rely on this app. It's a good general app for gauging calories and distances. When I compare it to my bike computer it's pretty inaccurate. However I have only been using the free version and have not yet explored all of the features. Still, pretty good app for free.
