Momentum-Firmware/applications/plugins/counter

Dolphin counter

This is a simple plugin for the Flipper Zero. It gives you access to a counter which you can increment and decrement using the up and down buttons respectively.

How to install this?

I'd recommend using flipperzero-ufbt, which is a lightweight tool for quickly testing Flipper Zero applications. The app will stay present on your device so it is not necessary to flash the entire firmware.
