User Reviews

Overall sentiment is positive about core gameplay and features like auto notes, privacy, themes, offline use, and a one-time price. Major downsides are paywalls for settings, inconsistent difficulty, problematic hints, no resume for unfinished games, and some UI/UX quirks. Users also request teaching hints and better progress export. The app shows active development and strong customization, but pricing and balance concerns temper enthusiasm.

Pros

Auto notes/pencil marks (pre-filled notes) streamline solving
Privacy/ad-free with no data collection
Theming and customization options including dark mode
One-time price / no ongoing subscription
Works offline

Cons

Settings and features locked behind paywall or paid upgrades
Inconsistent or overly hard difficulty balance across levels and updates
Hints are too intrusive/limited in usefulness and can auto-fill
No save/resume of unfinished games (no history for unsolved games)
UI/UX issues such as hard-to-see borders or tap-target precision and some modes being restricted/free

I had hoped that this app would teach sudoku concepts, rather than just give a hint by telling you a number. I had a great sudoku app that is no longer made, and it let me scan games in as well as taught different techniques. So when you asked for a hint, it would say something like “look for a naked pair” rather than saying “do you accept defeat?“ I think that’s just insulting and stupid because it doesn’t teach anything. It just fills in the number for you.

Latest update was 3 years ago, and I purchased the premium version to support the developer. I really hope this app continues to receive updates, as it has a lot of potential. I do have a few suggestions: * Add an option where using the “X” also removes notes from cells * Include a toggle that allows up to 3 mistakes (can be edited) per game * Expand customization options. More colors or even a color wheel would be great Overall, I’d love to see this app continue to grow with more features and improvements.
