Frequently asked questions
Where do I put the phone?
Beside the gate, in the gate’s own plane, looking along the gate line, across the flight path. Never in front of or behind the gate. Seen from the phone, the gate is edge-on: centre it on the line shown on screen.
Which goggle recordings can I import?
MP4, MOV and AVI files, from the Photos library or the Files app. Analog goggle DVRs that record Motion-JPEG AVI (often 640×480) are supported. Show the sync code on the phone to the drone camera before the race so the app can line the video up with the race.
How do I restore my OverLap Pro purchase?
Open Settings › OverLap Pro and tap Restore purchases, signed in with the Apple Account that bought it. Pro is a one-time purchase and follows your Apple Account on all your iPhones.
How do I back up my data?
Your tracks, races, laps and packs are stored on the iPhone and are included in its iCloud or computer backup. Imported goggle videos are left out of backups because of their size: keep the originals from your goggles.
