Sudoku Trainer Pro 2.3 - Improve your techniques with this sudoku app!

I am a solo dev and I’ve been a Sudoku lover 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 IAPs. 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 hood? * 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
