The iDotMatrix App
A free companion app that turns programmable LED pixel displays into a canvas for everyone.
What is iDotMatrix?
iDotMatrix is a mobile app for controlling LED dot-matrix displays — the colorful programmable pixel screens you see on desks, shelves and in creative spaces. With the app you design pixel art, build animations, show a clock or scoreboard, and react to music, then send it all to your screen over Bluetooth.
It is built for makers, families and anyone who wants a fun, customizable display — no coding required.
Our mission
We believe a pixel display should be as expressive as your imagination. iDotMatrix makes creative LED displays approachable: simple enough for a child to design their first pixel character, deep enough for enthusiasts working with 64×64 screens.
- Free on iOS and Android
- Available in 18 languages
- Thousands of free designs in the cloud library
