The mellow application was initially available for both Android and IOS. However in 2020 the backend servers were stopped and the applications removed from stores.
There is currently an effort to keep the android application running, using mock backend endpoints. This is needed to enable Pro mode and use the board at maximum speed. If you are interested, ping me at felo_na_gamo@outlook.com
The repository of the current work (private) is here.
If you find someone already having an IOS application you can use theirs to enable your board, but you have to meet personally.
The official page of the Mellow app is here.
