Yep, nothing beats Sync, although the other existing apps are great, and have been great since the beginning if you ask me.
If you wanna know why I chose Sync instead of any other app is because the damn app can survive even the worse ROM you use and it doesn’t matter how atrocious your RAM management is, you are likely never gonna miss the position you left when you minimize and open other apps.
The app basically saves the state where you were and it is highly unlikely that you lose the track of it, even on aggressive RAM management ROMs like MIUI, it still stands better than the others, I experienced the same with Sync for Reddit.
It is, but it would be like saying Android is just another Linux variant.
What I want to stress in my initial comment is that the OS is so heavily modified and focused on optimization and RAM management, that it can’t hardly work for power users when multitasking is on the board.
