Det finnes ikke noe sakssystem, ingen chatbot og ikke noe hjelpesenter med fire hundre artikler. Det finnes en e-postadresse og en liste over feil, og begge ender hos den som skrev appen.

GitHub-issues
Til alt du heller vil ha offentlig — og til alt andre må kunne finne senere, som gjelder de fleste feilmeldinger.
Når en oppgave er feil
Send fire ting, så tar kontrollen ett minutt.
- FEN-en som vises på oppgaveskjermen — hold nede for å kopiere den.
- Trekket du gjorde, og trekket appen kalte riktig.
- Hvilken modus du var i.
- Appversjonen, fra informasjonsskjermen.
Oppgaver motsier nå og da et dypere søk, og de motsigelsene samler seg i lange, stille, høyt vurderte stillinger hvis poeng ligger dypere enn kontrollen nådde. Det er en grense for kontrollen og ikke en feil i oppgaven — men det er verdt å vite hvilke det er, og den eneste måten å vite det på er at du sier fra.
Spørsmål
Stilt ofte nok til å bli skrevet ned.
- Does it need an internet connection?
- No. The engine, the puzzles and your progress are all on the device. The single exception is online play, which needs Game Center to reach the other person.
- Is there an account?
- There is none to create. Your ratings and history live in the app’s own container on your device, and deleting the app deletes them.
- What is free?
- Playing is free and stays free — against the engine, against a person over Game Center, and the nine hundred games in Watch — all unlimited. On top of that a free account gets five a day of each kind of training: five tactics puzzles, five Rush runs, five positional exercises, five endgame drills and five games to judge. The allowance resets at nine in the morning, local time.
- Why is there no advertising?
- Partly taste and partly licence. The app links two engines — Stockfish under the GPLv3 and Reckless under the AGPLv3 — and compiling a proprietary advertising SDK into the same binary would make the combined work undistributable under either. Selling the app is fine; copyleft has never forbidden charging. Bolting a closed SDK onto it is not.
- Are my puzzle ratings the same as a FIDE rating?
- No, and they run several hundred points higher. They measure progress against yourself, not strength against a field.
- Where do the puzzles come from?
- Most are from the Lichess puzzle database, released into the public domain under CC0, carrying ratings calibrated against millions of real solving attempts. The rest were mined locally by having Stockfish play itself and keeping only positions where one move is far better than every alternative.
- Can I see the source code?
- Yes. The app carries the GNU Affero General Public License version 3 — the terms Reckless brings with it, which the GPLv3 of Stockfish permits combining with — and the complete corresponding source is published on GitHub.
- Which engine am I playing?
- Whichever you chose in Settings. Stockfish and Reckless are both compiled into the app, and one of them plays, grades and labels everything. They are not equivalent: Stockfish can be asked to play anywhere from about 1400 to full strength, while Reckless has no strength limiter and plays at full strength or not at all.
