Buggy app. Not worth the money

I tested this app using my and my opponents scoresheet from a 60 move game (ie 120 moves in total). From my scoresheet the app got 31 moves wrong and from my opponents scoresheet 22 moves wrong. That is a very high error rate (52% and 37%). My opponent and I concluded we would be quicker to input the moves ourselves than use the app. Worse, you can’t even download the moves to PGN without paying for the app ($18 USD) so I don’t even know if that feature works or not. I do NOT recommend this app.

Response from developer

Hi, thank you for your message! The app always tries to generate a legal sequence of moves. This means that if it incorrectly recognizes one of the initial moves, it may not be able to generate the subsequent moves correctly, even if the notation itself is recognized correctly. Because of this, it isn't really possible to make statements such as "the app got 31 moves wrong." Whenever you correct a move, the app regenerates all subsequent moves. In your case, it would probably only take about five corrections to reconstruct the entire game correctly. I would really appreciate it if you could give the app another try. The following video may also help you: https://www.youtube.com/watch?v=UxWUcbopu08 You can also send me the scoresheet at support@chessscanner.com, and I'll send you a video showing you how to digitize the game.

Saves a lot of time

Very nice app that helps me with tournaments. Saves so much time to digitize chess games. Easy too use, good quality of recognition. Usually I have to correct one or two moves that I wrote unclear.

Not worth the money

The app costs about $48 per year if you want to download the PGN.

This might be worth the money if the app looked at subsequent moves to try to figure out what the note was, but it does not.

In the game I input, the app got move 10 wrong, and instead of using the rest of the game to figure out move 10, it just moved the named piece to a random square for the rest of the game.

In the time it took me to correct all the moves, I could have just about entered the whole game.

The feature that is useful is that once I start entering corrections, it made new guesses, and I didn’t have to re-correct the rest of the game.

I am just not sure this feature is worth $48 per year to me.

Response from developer

Hi, thank you for your message! Depending on your country, the app with all its features costs around $18 per year. During the initial move generation, the app considers subsequent moves and also updates when you manually trigger regeneration (though this is not recommended). It's generally faster and more battery-efficient to use automatic regeneration(without analyzing subsequent moves) and then adjust any potential mistakes. The regenerated moves depend on the detected texts, which you can view by tapping the score sheet icon at the top while in edit mode. The trick is not to look at the moves one by one but to check the background color of the moves displayed next to the score sheet, scanning from top to bottom to spot any incorrectly recognized moves. My best guess is that some fields on the score sheet were not recognized correctly in your game. There is also a helpful YouTube video explaining the app here: https://www.youtube.com/watch?v=UxWUcbopu08. It's definitely worth a try! :). If you'd like, you can send me your score sheet at steffen@chessscanner.com, and I can then share a video of my process for recording your game.

Only Useful If Paid

I only downloaded this to save time getting the PGN to study. After I learned I had to pay to do that or open in a chess app, I uninstalled

Response from developer

I understand your frustration regarding the cost of accessing PGN files. I aimed to make this solution as affordable as possible while still covering expenses. My main goal is to eliminate the need for physical score sheets and to make your games accessible at any time. Additionally, there is a web version where you pay per game, and the first three scans are free. I would love to hear your thoughts and any ideas you might have!

Spannend

Das Umwandeln von Schachpartienotationen in Partieformulare klappt. Manchmal wundert man sich aber, warum deutlich geschriebene Züge falsch interpretiert werden. Das Korrigieren dieser Züge ist sehr einfach gelöst und selbsterklärend. Ob der Preis aber gerechtfertigt ist, muss jeder selbst entscheiden. Lohnen tut sich die App, wenn man viele Partien eines Turniers erfassen will. Wer nur eigene Partien erfasst, kommt bestimmt ohne zurecht.
