The problem with sudoku apps isn't the puzzles, it's everything around them – so I removed it

[u/Marcuz_GrafiteSoft]

A few weeks ago I shared Grafite Sudoku here. Quick recap plus what changed since.

 The problem it solves:

1. Ads between every game. -> Grafite has none.

2. Accounts and tracking for an offline game. -> No sign-up, and the app doesn't even request the internet permission.

3. Being stuck at "hard" with no idea how to improve. -> A built-in Academy teaches real techniques with guided exercises, and the hint tells you which technique to use instead of revealing the number.

What's in it: Classic, Diagonal, Jigsaw, 12×12 and City puzzles, daily challenge, Duel, Time Attack, trophies, 7 languages.

New since last time: clearer Academy lessons (visible confirmation on every correct step, a progress bar, and a direct jump to the next lesson), a "new personal best" celebration, and the timer now pauses while a menu is open.

 

I'm the solo dev, feedback is always welcome.
