How it works
From a finished game to a useful review.
- 01
Import
Paste or share PGN, open a .pgn file, or request a completed public game by Chess.com or Lichess username.
- 02
Analyze
Choose Fast, Balanced, or Deep. Arasan 22.3 runs inside Quiet Move on your iPhone—never on a cloud engine.
- 03
Understand
Review the key decisions, compare your move with a stronger line, and turn positions from your games into practice.
The shape of the game
See the whole game. Then the decision.
Move through Evaluation Flow, stop at a Key Moment, and keep the board, explanation, and stronger line in the same line of sight.
- Move classifications and accuracy
- Key Moments and stronger continuations
- Practice built from your reviewed games
A real decision, in context
One move can be enough to understand the game.
This example comes from a completed public game already used in Quiet Move. The point is not only that 18.e5 was a mistake, but that the board, evaluation, explanation, and stronger continuation stay connected while you review it.
A complete review, kept focused
From overview to practice.
Quiet Move organizes engine analysis around decisions you can revisit, without turning the review into a wall of raw output.
- 01
See the shape of the game
Evaluation Flow connects the board, every move, and the moments where the position meaningfully changed.
- 02
Focus on key decisions
Key Moments brings the consequential choices together, so even a long game becomes a review you can finish.
- 03
Compare and explore
Keep the move you played beside a stronger continuation, with classification, evaluation, and explanation in context.
- 04
Practice your positions
Turn important moments from reviewed games into focused puzzles drawn from positions you actually encountered.
Training from reviewYour position, not a random puzzle
Engine-grade analysis. On your phone.
Local by design. Clear about how.
Arasan runs inside Quiet Move
Quiet Move bundles classical Arasan 22.3, the open-source chess engine by Jon Dart, and runs it locally on your iPhone.
Quiet Move builds the review
Engine results become Quiet Move’s classifications, accuracy, Key Moments, comparisons, explanations, and training tools.
Your library stays on your device
No Quiet Move account or analysis server. Provider requests happen only when you choose to import; review works offline afterward.
Good questions
Analysis, plainly.
What games can I import?
Paste or share completed PGN, open a .pgn file, import by Chess.com or Lichess username, or share an exact public Lichess game link. Quiet Move does not scrape Chess.com game pages.
Does analysis leave my iPhone?
No. Chess analysis runs inside Quiet Move. A provider import needs a connection and goes directly from your device to that provider only when you ask for it.
Why might the accuracy be different?
Quiet Move calculates its own accuracy and move classifications from its analysis settings and methodology. Its percentages and labels may differ from Chess.com or another analysis service.
Can I use it during a live game?
No. Quiet Move is designed for completed-game review and does not suggest moves during live play or import games in the background.
What is Quiet Move Plus?
The complete analysis and training loop remains free. The optional one-time Plus purchase adds weakness trends, smart ordering among puzzles already due, extra board themes, and annotated PGN export. No subscription.
