Best app ever!!!!! There is coding with and without the lego boost. It also has simple building and coding lessons. You can even use lego city with it!!!!! There is also a section to build your own robots. In the box it says you can build 5 built in modles when THERE IS ACTUALLY 6!!!!!!! You can also sign in with your lego account. I do reccomend this app.

App is very good when you get the firmware updated, which the app refuses to do. Fortunately another review noted the firmware could be updated via the lego powered up app, simply start a new project and it autodetected the kit, when it was on, and updated the firmware. This app then worked fine. I have to say I'm disappointed if you are still selling this great toy the app needs supporting properly, its clear lots of people are getting this bug.

Firmware update enforced but it does not work. I had to install "Lego powered up" and select any set to update the firmware. I bought a Lenovo tablet with Android 11 just for this and is not compatible with the app! This review is not for the robot itself or for the app itself because the UX is great but feels like we got a brand new car without keys.

The app crashes when starting it. It just doesn't want to open anymore. Before I could only open it on the main user of the tab, et, but now it refuses to even open.
