The micro:bit app is the essential companion to the BBC micro:bit, the pocket sized programmable computer. The app allows you to flash any micro:bit hex file to your device, as well as including online access to the Microsoft MakeCode editor for simple block-based programming. When your program is ready, the app beams it to the micro:bit via Bluetooth wirelessly. Easy-to-follow screens lead you through the process of pairing your iPad (or iPhone) to the micro:bit and then transferring your program code. Compared with previous versions, the micro:bit app Version 3.1 contains these additional features: • A simpler pairing and micro:bit discovery flow • The micro:bit V2 can be put into pairing mode by triple-tapping the reset button • Retrieval of the micro:bit data log files from off your micro:bit • Pair with any number of micro:bits • Choose which micro:bit is currently connected • Store HEX files in the app • Choose a HEX file for flashing • Export and delete HEX files • Import stored HEX files directly into JavaScript Blocks editor • Rapid download from JavaScript Blocks editor • Monitor data detected by micro:bit sensors • Use the range of micro:bit Bluetooth services in real time • Display messages on the micro:bit LEDs • Send control commands to the micro:bit buttons and pins • De-bug your program code while it is running in the micro:bit • Use a simulated gamepad to send commands to the micro:bit • View camera images ready for taking photos or video As well as providing more flexible handling of your program scripts and HEX files, a major addition in Version 3 is the Monitor and Control page. This lets you 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 ideal for exploiting Bluetooth services in real time, and for de-bugging your program code while it is running in the micro:bit. The MakeCode code editor now requires iOS 13 or later.

Verdict
The clearest difference is rating: micro at 3.3 against Kai's Eye Robot Tracker's 2.3. micro also leads on ratings volume (90 vs 3) and iOS requirement (12.0 vs 15.0). Kai's Eye Robot Tracker's advantage is review sentiment (80% vs 43%) and update cadence (every 6 weeks vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
micro holds the better App Store score, 3.3 against 2.3. That said, the two scores are not equally well evidenced: micro has 90 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 43% of micro's written reviews are positive against 80% of Kai's Eye Robot Tracker's, so the app with the better star average is not the one people write more warmly about.
micro ships an update every 7 months, Kai's Eye Robot Tracker every 6 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
