💰 Revenue: Marginal — $205 - $1286/mo · INDIE tier · medium confidence, trajectory unclear.

📍 Market: Not yet charting in any of the 9 monitored markets.

📝 About this app

This application is to vibrate your phone when your out-going call is answered by the other side. You don't have to listen to or look at the phone before the call gets connected.

Just tested Android 10 on Pixel3a, with the additional OutCallWatcher app installed, and it works well.

*For former users*

If you have the old version installed and it works, please IGNORE this update. If the old version does not work, this might not work either. But if you do want to give it a try, you have to UNINSTALL the old version in order to install this update.
