Rate the Android or iOS application/program you use most frequently.
Can be anything.
When using system built-in apps, please mention what firmware are you using.
For me, it's either
Neutron (while charging) or
Poweramp (while on battery).
Both of them are powerful, but Neutron gives better quality and a ton of more features and more control, for a price of higher battery consumption, which is highly visible.
This is why I give them almost the same rating.
