What is Reddit's opinion of Sudoku Dojo Free?

From 3.5 billion Reddit comments

Well, I'm certainly biased, as I was in the same place like you and developed my own solution.

Recently, I posted a description of the disadvantages I saw in most other apps and a list of features.

EDIT: corrected link

Warning - self promotion: I found the sudoku programs that give you "hints" by solving - more or less - random cells and don't give the reason for it quite annoying. So I implemented my own improved version:

If you have an Android device, you could try it: Sudoku Dojo - it gives you textual and graphical explanation for each hint that you request.

It also

• allows you to use conjugate pairs/coloring
• creating (or entering) sudokus, so that you could enter this sudoku and use the hint feature to get an explanation

There is currently no naked or hidden single in this game - meaning there is no cell that has only one remaining candidate (naked single) and no house (i.e. row, cell or box) that has a candidate in only one cell.

So /u/Pistolcrab's advice to fill in pencil marks is the way to go. Once you have done that, you could start to eliminate candidates until you find singles.

Examples:

• The first row contains the candidate 7 at the positions r1c4 and r1c6. Both positions are in box 2. As each row has to contain each candidate, we now know that the 7 in the second box has to be in the first row. Even though we do not know which of the 2 positions is correct, the candidate 7 can be eliminated from two other cells in box 2 (r3c4 and r3c6).
• More or less the same applies to candidate 6, column 2 and box 4: The only remaining positions of 6 in column 2 are r5c2 and r6c2, both of which are in box 4. Thus no other cell in box 4 may contain 6.

If you happen to own an Android device, I'd be very happy, if you gave my app (Sudoku Dojo) a try. As soon as you have entered pencil marks (or let the app do that for you), it'll give you logical hints, i.e. a full description and graphical display of the logic needed to make the next step towards the solution. I've posted recently about its features.

If you want explanations like this, I'd be very happy if you gave Sudoku Dojo a try.

I posted a description of the features here.
