Frequently asked questions

The timing device (Bluetooth) won't connect

• Make sure Bluetooth is turned on for your device.
• Make sure the app's location / nearby devices permission is granted (required for BLE scanning on both Android and iOS).
• Check that the timing device (Smart Timer / Smart Timer for Four Runners) is powered on and has sufficient battery.
• Make sure no other app or device is still connected to the same timer — only one connection is allowed at a time over BLE.

How do I export my measurement data?

Recorded data can be exported as CSV or Excel from the app's share function. The exported file can then be saved or shared using whatever method your device offers, including email or cloud storage such as iCloud Drive.

Which timing devices are supported?

FASTRun Smart supports the "Smart Timer," and FASTRun Smart for Four Runners supports the "Smart Timer for Four Runners" (both manufactured and sold by YY-Factory).
