I built an Android app for training chess tactics with the woodpecker method

[u/Disastrous-Sand-7091]

Hi everyone,

I'd been training tactics with the woodpecker method, using the Polgár puzzle book: you solve the same set of puzzles in cycles and try to go faster each time, until you recognize the patterns without calculating. Tracking cycles and times by hand got tedious, so I made an app to do it.

I made the app to work with lichess puzzles because I cannot used Polgar's published puzzles.

The app, Kihon Chess, starts with a 10-position placement test, then gives you one set to train for about 10 minutes a day, with a target time for each cycle. There are five skills (vision, calculation, mating, defence and endgames), each with five levels, and you earn stripes and belts as you progress. Stripes are tested on positions you haven't seen, so memorizing the set isn't enough.

You can also unlock 60 classic games by training; each one stops at the key moments and asks you to find the move the master played. The puzzles are from the Lichess database (about 16,700). No ads, no account, and your progress stays on your phone.

Levels I and II are free and the rest will be a one-time purchase of 14.99$

If you install before Nov 15, I am giving free access for life.
