## Review summary

The app is praised for easy, beginner-friendly block coding and strong Lego robotics support, with high user satisfaction and recommendations. However, users frequently report Bluetooth connectivity problems, lag/bugs (notably in the animation editor), missing EV3 support on Android, device compatibility and reinstall issues, and occasional difficulties downloading extra activities. Improvements in Bluetooth performance have been noted, but reliability and cross-platform EV3 support remain key areas for attention.

- Strong focus on Lego coding and building bots; engaging and fun
- Highly regarded by fans; widely recommended
- Bluetooth connectivity bugs reduced / overall improved performance

### Cons

- Bluetooth/connection issues persist (spike or hub pairing problems)
- Lag and bugs, especially in the animation editor; occasional instability
- EV3 support missing on Android (limited to other platforms)
- Device compatibility problems (new devices not supported; reinstall issues)
