It could be great. Someone should rethink the camera orientation lock thing, and separate record button. Putting it in. Settings where it records video when you click record session is obvious fix.

I’ve used this app for 2 separate track days now. While I’ve found the overall quality of data, export options and GPS tracking to be solid, the UX is a complete nightmare, especially given that this is a paid $20 app. I had multiple sessions not record the video feed because the UX is not very clear about when the camera is active vs when it’s not. Not to mention, the whole landscape vs portrait orientation lock just adds more confusion because it can end up with the camera orientation locked but the overlay changed. Also why are both the “STOP” and “START” buttons shown as red? I literally missed my best session because there is no easy visual cue for whether the video feed is being recorded or not. This could be as simple as giving an option in the settings to always turns on and record camera feed when recording a session. I was originally going to give it 4 stars instead of 3 because when it works, it is genuinely good. But someone else also brought up the UX issue and the dev response was “it’s a tool not eye candy”. As a dev myself, this is not a good sign. I understand that when your work is up for public comments, it is not easy to see it get criticized, oftentimes unfairly. But the bad UX is a serious issue for an app that’s used as a tool for track days, where we don’t have time to fiddle about as our session is about to start. There are far more important things like safety measures to worry about rather than try to figure out if the app is recording the video feed or not
