### 3/5 — One time fee

*2024-12-05, version 2.4*

The app seems ok but the promised one time fee is not accessible. It only has the monthly subscription. With the promised option, I would add at least one star.

### 3/5 — From photo not working with iP 14

*2023-06-20, version 2.4*

Enjoy this app but after phone upgrade  to iPhone 14, scan game from photos doesn’t work, sees photo but does not process into game. Still works on my older iPad. (Also tried on another iP 14 as well)

### 5/5 — TQ TQ TQ

*2020-05-17, version 2.4*

A perfect App

### 4/5 — Pencil marks

*2020-05-17, version 2.4*

If I fill in the final number on a square in a box, the pencil marked number in other squares in that box as well as squares in the corresponding rows and columns should automatically disappear. As it stands now, I am required to manually do the removal.

### 5/5 — Jim V

*2020-02-06, version 2.4*

Great sudoku app. Definitely the best on App Store!! 👍

### 2/5 — It does work.

*2020-01-30, version 2.4*

User interface is not great, no easy way to update multiple cells quickly. Scanner doesn’t work well. Misidentifies values, places values where there aren’t any and selecting rightmost column is difficult.

### 5/5 — Excellent!

*2020-01-06, version 2.4*

Brilliantly designed app and love the ability to take pictures!
Works flawlessly

### 1/5 — Scanning Broke

*2019-12-17, version 2.4*

Used to use this app all the time. It’s fairly easy to use, notes feature could be better, would be nice if numbers grayed out when no more left to place; but the app became useless to me when it would no longer accurately scan images:screen caps of puzzles from the newspaper. Sent in feedback, never got a response, still broke.

### 4/5 — But why...

*2019-06-11, version 2.3*

...does it call itself "QR Reader"?

### 3/5 — Pretty good, but scanning got worse

*2019-06-04, version 2.3*

Scanning used to work great but with recent updates hardly works at all with my local paper. What changed?

Also, if I reset a puzzle I have to clear notes in each cell. Reset should clear all notes. Now they are not showing after reset, but entering a note brings all old notes back. 

Overall a good app. I prefer it for solving the puzzle in my morning paper.
