## Review summary

Users mainly praise the ability to input Sudoku numbers by handwriting directly on the board and the slick, pen-and-paper feel, along with easy erasing and a generally fun experience. However, notes are a persistent flaw, being non-customizable and limited to certain candidates. Handwriting recognition can misread digits (8/9, 6/9) and erasing can be fiddly, sometimes letting errors slip through. Some wish for color-coded notes and more reliable input, and a few note that hint banking and error-prevention features have changed in newer updates.

### Pros

- Handwriting input lets you write numbers directly into cells
- Slick, paper-like interface
- Easy erasing with a double-circle gesture
- Fun and addictive to play
- Hints are helpful

### Cons

- Notes feature is restrictive and non-customizable, showing only certain candidates
- Handwriting recognition can misread digits (e.g., 8/9, 6/9)
- Erasing can be finicky and require repeated attempts due to motion controls
- App sometimes allows errors even when configured to prevent them
- Desire for color-coded or more flexible notes
