### 5/5 — Perfection

*2026-08-30, version 5.0*

The Solver has modes of one numeral or all. Very useful. I’ve tried others that make mistakes.  This solver is perfection.

### 5/5 — It works

*2026-08-16, version 5.0*

Easy to enter numbers

### 5/5 — Alberto

*2026-08-11, version 5.0*

Clear to use the tool. Would like more insight into solutions and be able to walk through the solution by suggestion

### 1/5 — Duplicates not indicated

*2026-05-28, version 5.0*

The app should indicate when a number is doubled on a line or cell

### 1/5 — Doesn’t work

*2026-03-05, version 5.0*

Keeps giving unsolvable even on brand new puzzle

### 5/5 — Terrific

*2026-01-04, version 5.0*

I wish I could see the logical flow chart of computer.

### 1/5 — No hints, only whole puzzle solved

*2025-11-16, version 5.0*

In the pictures, it says you can input a grid and get hints as to possible next moves but I can’t do this. The only option is to choose a square and have it solve that (without it explaining how) or solving the whole thing with no explanation.

### 2/5 — No hunt option available

*2025-02-09, version 5.0*

My primary goal was finding an app to help me problem solve with hints and maybe explanations/clues how to narrow it down. I didn’t have a problem with uploading an image or filling in numbers like some others reported. I just couldn’t make use of hints, which makes this useless to me. I don’t want to just have a puzzle solved for me. This particular app just wasn’t for me.

### 1/5 — Dynamic Island  Problem

*2024-10-15, version 5.0*

I can’t believe the developers didn’t catch this. The instructions (at least I presume they are instructions. I can’t really see what they are) that this app gives are LITERALLY right underneath the iOS Dynamic Island on my iPhone 15 Pro Max, and I presume it would be the same for all other phones that have that feature. With that being the case, the text is useless which makes the app moderately useless as well. Good thing the ads do not get interfered with by the Dynamic Island. 🤨

Bad app design. If they update it, I will take another look.

### 1/5 — Poor as no option to delete a nbr thats wrong

*2024-10-09, version 5.0*

Poor as no option to delete a nbr thats wrong
