Letsgo

Letsgo starts and stops your GoPro recording based on the speed you set. This super easy to use app will save you tons of editting time by only having your GoPro recording when your Android device is moving. A background mode is available to allow GoPro control even when Letsgo is in the background.

To use:

Configure your GoPro camera with the GoPro mobile app (one time)
Put your GoPro camera in “app” mode (wifi on)
Launch Letsgo and choose your device.
Letsgo will automatically connect to your GoPro and start/stop video recording.
