Great customer service, pretty good app.

This app has lots of potential and works pretty well. It measure to the single mph to the hundredth of a second and is way way cheaper than VBOX. There’s pretty limited functionality of how you can actually interact with the data it measures and I hope their short-term plans include vastly expanding that. The UI is clunky and can only be used in vertical mode. But I’m happy to be able to actually have the functionality it provides at all (with the $150 DRAGY GPS device of course) so I’m giving it four stars.

App needs some work, trying before buying unit

Heard some good things about this unit and app and wanted to see for myself. I got the app 2 minutes before typing this just to see how the interface is and I cannot even get it to open. It keeps telling me I have no internet connection. Obviously some sort of bug/error. If I cannot even open up the app how can I use this product so what’s the use of buying the unit?

Edit: The dev should put some sort of an offline mode because if this thing has issues with internet then it isn’t really usable. Why would it need internet anyways aside from logging into your account. I’m sure you could use all the features without internet connection if such a mode or setting was available.

Edit 2: Just deleted and reinstalled and it loaded but when I got into the main interface the no internet connection error kept popping up.


App Crashes and is Extremely Slow

Although I like the concept of the app, I’ve had problems with the app crashing somewhat regularly and the app performance is pretty terrible. When you try to load your own profile or your performance times, I have no idea what they’re doing but it takes 20-30+ seconds (why can’t you cache some of the data locally - it’s not a ton of data!!). I just tried to check my messages in the app and it repeatedly asks me to log in. The app is borderline unusable - you can log your performance time but accessing it is difficult.

Also, when it records your performance it will give you different slope measurements for the exact same spot. One time it says 0% spot on and the next run from the exact same spot shows invalid bc it’s -1.3% slope. That’s way too much variation.
