The iOS micro:bit app

Code the micro:bit using your iOS mobile device

About the app

You can program any micro:bit in Microsoft MakeCode using our iOS app. It uses Bluetooth LE (Low Energy) to transfer programs wirelessly from your iOS device to the micro:bit, so no USB cable is needed.

Download from the App Store


To transfer your code from the iOS app to your micro:bit, you need to pair it.

Downloading this HEX file and transferring it to your micro:bit is a good way to start:

Monitor and control

The 'Monitor and control' section of the iOS app allows you to observe real-time data from the micro:bit sensors, send messages directly to the LEDs and control the micro:bit buttons and pins from your iPad or iPhone.

Monitor is also ideal for exploring Bluetooth services in real-time, and for debugging your program code.

These facilities are only available if you have added Bluetooth services to your program, or use one of the examples like ‘monitor-services’ which you'll find in the 'Flash' page of the app.

The micro:bit iOS app is developed by Insight Resources on behalf of the Micro:bit Educational Foundation.
