System Tuner rated 5/5 on Android Appz 10/2012

IT professional for more than 30 years, currently CTO of 1CHECK, a B2B SaaS platform. In 2009, in my spare time, I wrote my first Android app: a simple battery monitor. It grew into 3C, a set of 18 Android apps for battery, CPU, performance, system management, backup and Wear OS, with more than a 100,000 active users. Today I'm rebuilding them in Flutter, on top of the proven native C engine.
