Database program for statistics about mistakes I wonder if there is an application that will help with statistics for my own games. Of course - there are applications (eg. Scid, Chessbase) that allow to make some statistics out of database - but it mostly applies to openings. What I would like is to:
- import my games into the app
- run some kind of analysis (with more or less filters)
- get nicely presented statistical output by category

Sample scenario would be - I put all my standard games from 2016, and I want them to be scanned. After that I get report like:
- 40% lost because of tactical blunders
- 90% of draws were when playing black
- in 20% of won games I've reached endgame

It could be in some way done manually - so I could actually annotate the game with simple tags like: 'pawn endgame', 'slav opening' or 'tactical blunder' and put comments of my own or after I've analysed the game with the coach. 

My question is - does this kind of application even exist?
I've built a web tool (https://www.chessinsights.org/) that you can use to upload your games, filter them, and find mistakes you made. The tool is free and open-source.

I'm currently working hard on adding features. If there's something you really want added, just let me know, and I can work on it.
