Contrail for iPhone
Getting good traces
- Put your iPhone on a stand or the ground a few steps behind you, looking down the target line.
- Keep the ball and some sky in the frame. Contrail shows a level while you set up.
- Start recording. No need to tap anything: Contrail finds your ball on the first swing. If a ball is already down, you can tap it to lock focus and exposure on it.
- Hit as usual. Stop when you're done; Contrail finds the shots for you.
Trial and purchase
