Write your code on the phone, compile it on the phone, and flash the board directly over a USB OTG cable. No computer needed — the compiler runs on your device.
The desktop IDE, running on your phone.
Code is compiled on the phone, not sent to a cloud server. Works without internet.
Plug the board in with an OTG cable and write the compiled output straight to it. AVR and ESP32 supported.
Syntax highlighting, a word completion bar, multi-file projects and full-screen writing.
Watch the board output live, send data, change baud rates.
From Blink to WiFi and sensors; library examples are listed too.
Upload speed, flash mode, partition scheme and core debug level are in your hands.
The free version gives you 10 uploads per week and shows ads. Pro has no limit and no ads.
Your license key is emailed to you after payment. Just enter it under More > Sketch32 Pro in the app. Each key works on a single device.

10 per week, resetting on Monday. You can also earn extra uploads by watching rewarded ads. Pro has no limit.
One. It binds to the first phone you activate it on. If you change phones, message us from the Support screen and we will release the device.
A one-time payment; the license never expires. With monthly and yearly plans, Pro features switch off when the term ends and the app keeps working as the free version.
Some charging cables carry power only and have no data lines. If the board does not appear, try a proper OTG data cable first.
