v10.2.3

The best!

v10.2.1

New GoPro import UI doesn't show which laps each clip covers until you actually import it. It was easier to understand which clip(s) I need to import with the old UI.

Developer Response

The laps display is untouched. The auto-sync is still there, it's done automatically right after adding the files. No more button needed. If the added file come out unsynchronised, then it's missing GPS data or the session is not the correct one. I think the functionality is vastly improved, the UI logic is just new and unfamiliar.

v10.1.4

the export is buggy and unfriendly: Export is very slow and its performance the same on the low and high end smartphones. Export can die unexpectedly from various reasons. If you merge 2 videos together, export will add a picture with a timer for a time elapsed between videos, and you will get 20gb of a static image with a timer. Poor video quality after the export. The last version is asking for the license on every start, I run without internet and it doesn't record anything without a license

v9.1.3

Captures data appropriately. The only thing that might improve it would be the ability to export and share multiple sessions; you currently have to select a session, export it, then share it. This is probably not a big deal if you're doing AM/PM sessions on track day, but if you're using it for stage rally and each "session" in the program is a stage, you might end up with 14+ sessions over 2 days....

v9.0.2

Google Play app dumped my longer review so short and sweet: used for two seasons, rock steady connections, dead reliable.
