I agree with peak Sudoku. I search for Sudoku on Google Play and get 1000 responses. That is a search limit, who knows how many Sudokus there are. Someone starting out with Android might want to go for something a little more niche that has potential demand at first.
Also, the app is only in English as far as I can see. So they are competing in the most crowded market. Not that foreign languages save you with competition always. I tried to do an Android app in another crowded market, flashlight apps. Doing it in several languages did not help.
There are so many lacunae on Android, I have ideas all the time, yet so many people do yet another Sudoku app. They said they spent a lot of time on it. An MVP would have quickly told them what the demand was.
In terms of lacunae - only one app handles Microsoft Access files on an Android device AFAIK - my app. I based it off a popular LGPL Java library, the MVP took about two days or so of work, and did very little. I got a response, and suggestions, and built it up a little. I only have one competitor that I know of, and their database works off-device, and charges a fee after a trial period. There are gaps all over like that yet everyone goes for another Sudoku app, another flashlight app etc.
