About this project

Starting with Android 13, it's possible to control multiple brightness levels of the flashlight.
To be able to use this new feature I've developed this app.

Inspired by polodarb/Flashlight-Tiramisu 💛
Custom SeekBar built with code from massoudss/waveformSeekBar 💛

Features

• 🔦 dimming your flashlight level by level
• 🎚 shortcut buttons for different brightness levels
• 🆘 SOS flash button
• 📫 morse code flash mode
• ⏲️ Interval / BPM mode
• ⚡ quick settings tile for fast access
• 🔊 press both volume buttons for easy flashlight toggle
• 🔒 private, no ads, no internet connection
• 💯 modern Material You (M3) design elements
• 🎨 app colors adapt to device's system colors
