Sudoku Pro: Trainer & Puzzles

Sudoku without subscriptions, adverts, or tracking: unique puzzles, smart hints, 9 themes, and full offline privacy.

I am a solo developer and I’ve loved Sudoku for years, but lately, finding a good app has felt more like solving a puzzle itself - and not the fun kind.

I was tired of subscriptions. And why does a puzzle app need to track my location or share my data with advertisers? There is visual noise like flashing banners and "collect 100 gems" pop-ups that break my focus. I just want my coffee and a Sudoku. Call me a grumpy old man, but that isn’t much to ask for!

I wanted a "Zen" experience. So, I built it myself.

My goal: to create a clean, honest Sudoku for the App Store.

• Pay once, keep forever: no subscriptions, no hidden in-app purchases. Just a fair price for a premium tool.
• For everyone: I included 4x4 and 6x6 grids so I could play with my kids and teach them the logic, while keeping the Expert 9x9 tough enough for the pros.
• 100% privacy: the app works entirely offline. Your data stays where it belongs: on your device. I don’t track you. I only care about your feedback!

So what else is under the bonnet?

• Unique grids: every game is generated on the fly - 100% unique and 100% solvable.
• Tutorial mode: learn advanced logic (not just guessing!) with a guide that interacts directly with your current grid.
• Aesthetic choice: nine handcrafted themes (Rainbow, Newspaper, High-Contrast, etc.) with full VoiceOver support for accessibility.
• Share your logic: export a beautiful timelapse video of your solve.

Own the grid and rediscover the pure joy of logic.

Happy puzzling, Tobias
