Changelog

New features and meaningful improvements to OnlyMove, from the first opening trainer to today.

2026

  1. Back and forward move navigation in Explorer

    Inspired by player feedback

    The Explorer now lets you move backward and forward one move at a time, while browsing or editing. At a fork, choose the continuation or the path that brought you here. Your choices are remembered as you explore the line.

  2. PGN comments in courses, Explorer, and training

    PGN imports now preserve written comments alongside your course moves. Read and edit them in the Explorer, include them when exporting, and choose to show them during training. Different explanations from imported chapters stay together, so you can keep the reasoning behind a move as well as the move itself.

    Import a repertoire
  3. Training adds navigation within the current line

    Use the back and forward buttons to revisit moves in your current training line, including moves played automatically. Saved arrows and highlights appear on the board. Return to the current position to carry on from where you paused.

  4. Continuous extra practice without changing review dates

    Inspired by player feedback

    Finished your scheduled work? Keep practicing now flows from one exercise to the next without stopping. Practice ahead on lines you have already started learning, while your saved learning progress and review dates stay unchanged. Your practice time and accuracy still count toward your activity.

  5. Dashboard adds training statistics and streaks

    The dashboard brings together daily and lifetime training totals, accuracy, time spent, and streaks. The activity calendar distinguishes days you trained from days you cleared all new and due moves, so both showing up and finishing your work are visible.

  6. Opening Explorer for Lichess and Chess.com players

    Look up a Lichess or Chess.com player directly from Games, even if you have never played them. Browse their openings, move frequencies, and results on the board. Reopen recent players, load older games, or check for new ones as you prepare.

  7. Explorer suggests continuations from master games

    Reached the end of a line in the Explorer? Suggest continuation uses master games to help you extend it. You can also extend or shorten suggestions from your game reviews, then review the line before adding it to your repertoire. A Lichess connection is required.

  8. Support for repertoires of 10,000 user moves

    OnlyMove now supports and is tested with repertoires of up to 10,000 user moves. Faster saves and training performance improvements reduce pauses between rounds, especially with large repertoires or slower connections.

  9. Undo review changes caused by game misclicks

    Mark a repertoire deviation as “Not a real mistake” when it was a slip rather than a forgotten move. When the affected positions have not been reviewed again, OnlyMove can undo that game’s effect on their review schedule and remove it from your mistake queue.

  10. Courses support multi-chapter PGN imports

    Import a PGN with multiple chapters, choose which ones belong in your course, and preview how many moves are new or already present. Color hints help separate White and Black repertoires. For lines you already know, skip teaching and go straight to review.

  11. Courses with focused training and shared progress

    Keep openings in separate named courses and choose one to browse, edit, learn, or review. Shared positions keep the same learning progress across courses, and you can still train your whole repertoire together.

  12. Browser installation on mobile and desktop

    Install OnlyMove from your browser on a phone, tablet, or computer and open it in its own app window.

    Installation guide
  13. Support for seven interface languages

    The app is now available in English, German, Spanish, French, Brazilian Portuguese, Russian, and Ukrainian. Choose your language from the account menu.

  14. Generate a starter repertoire from your games

    Build a starter repertoire from your own games. OnlyMove suggests lines drawn from your play, and you review them before saving and starting training.

  15. Opening mistake review with suggested repertoire fixes

    Find opening mistakes in your synced games, get a suggested improvement, and add the line to your repertoire. Mark games as reviewed to keep track of what still needs attention.

    From a game to your repertoire
  16. Repertoire Explorer with editing and PGN import/export

    The Explorer brings your lines together on one board, including positions reached through different move orders. Browse, edit, and review changes before saving. Import and export PGN to move lines between OnlyMove and other tools.

  17. Lichess and Chess.com games update review schedules

    Connect Lichess and Chess.com accounts to compare your games with your preparation. Moves you remember reinforce your learning; forgotten repertoire moves come back for review.

    How games feed training
  18. Training moves to FSRS

    Training now uses FSRS, an adaptive spaced-repetition algorithm, to schedule each move’s next review based on your answers. Forgotten moves return sooner, while familiar opening moves can play automatically so you can focus on positions that need practice.

  19. Engine evaluations and statistics from master games

    Explore alternatives with engine evaluations and master-game statistics while working on your repertoire.

2025

  1. Daily training totals and review indicators

    Daily training totals and review indicators help you see what needs another look.

  2. Repertoire editing, annotations, and opening filters

    Create and edit opening lines, add arrows and highlights, and focus training on a chosen opening.

  3. Initial opening trainer with saved progress

    Practice opening lines on an interactive board, with your repertoire and training progress saved to your account.
