I’m using my mooshimeter with an Android device (every day). Sure, it’s not 100% plug and play, there are issues, but it’s far away (for me) from saying it’s a fail. Sometimes it’s needed to swipe the app from the process table, because it’s in a state where a connect is not possible (or the app means the mooshimeter is in firmware upgrade mode (but according to blink code, it’s not)). Another problem is a low battery, my device is unstable when the battery is lower than 40-50%.
