Stockfish · Plain language · One-time option
A Chessis alternative
with training built around the analysis.
Chessis is a well-regarded on-device chess analyser on Android, with Stockfish, plain-language game reports, PGN import, and one-time Pro pricing. As of 29 October 2026, Chessis is no longer on the US App Store, and its website links only to Google Play. Chessful takes the same approach on iPhone, iPad, and Mac, and then turns your mistakes into the puzzles in your daily training. Around that sit 156 free lessons, 15,000 puzzles, 96 endgames, and 40 opponents to play.
How does Chessful compare to Chessis?

About Chessful
Questions
FAQ
What is the best Chessis alternative for iPhone?
Chessful is the closest match to Chessis on Apple devices. Both run Stockfish on the device, explain your mistakes in plain language, and import PGN files. Chessful runs on iPhone, iPad, and Mac with one Universal Purchase, while Chessis puts Android first. Chessful also builds daily training from your mistakes and includes 156 lessons, 15,000 puzzles, 96 endgames, and 40 opponents to play.
How is Chessful's analysis different from Chessis?
The analysis is similar: both run Stockfish locally and report your mistakes in sentences. Chessful's mistake card shows what you played, what was best, why, and the line that punishes your move, worded for your coaching level and tagged with one of 10 mistake types. The bigger difference is what comes next. Chessful turns those mistakes into the puzzles in your daily training, and spaced repetition brings back the ones you miss.
Does Chessful support PGN import like Chessis?
Yes. Open a PGN file from Files, iCloud Drive, or AirDrop, or paste PGN text. One import takes up to 500 games, flags duplicates, and lets you pick which side you played. That covers games exported from Chess.com or Lichess. Chessful doesn't fetch games by username.
Why use Chessful instead of Chessis on iPhone?
Chessful is made for iPhone, iPad, and Mac, with one Universal Purchase for all three, while Chessis prioritises Android. It adds daily training built from your own mistakes, 156 free lessons for learning the game, 15,000 puzzles in 53 themes, 96 endgames against Stockfish, and 40 opponents from 400 to 2400 Elo to play in the app.
Are both apps a one-time purchase?
Both offer one. Chessful has a $29.99 lifetime option alongside $2.99/month and $17.99/year subscriptions, each with a 7-day free trial, and a free version with daily limits. Chessis sells a one-time Pro purchase (the price varies by region).
