TAKE A BREAK Going on holiday, or have a tournament coming up? In Settings → Training, "Take a break" pauses all your training for one to seven days: no lines fall due and no reminders arrive. When it ends, your schedule picks up where it left off - a line that had three days to go still has three - and a reminder welcomes you back. You can end the break early at any time. PAUSE A REPERTOIRE Choose "Pause" from a file's menu in My Repertoire to set it aside for as long as you like. Its lines stop coming up in your reviews and in Critical Positions, and all their progress is kept. "Resume" brings them back, on the same schedule. HEAL WHEN SOLVED A new switch in the Critical Positions puzzles, also in Settings: when it's on, getting a position right on the first try removes it from your critical positions. WHEN THE LINE COMES BACK The Completed! page now tells you when the line will come back to you: "Next review in 6 days". CHECK A HIDDEN LINE In Reorder lines, tap a hidden line to open it and check it without bringing it back. The last one you opened is marked in orange, so you know where you left off. AND ALSO - With your phone's volume at zero, ChessFlow's sounds stay silent. - The Critical Positions count updates as soon as you finish a round.

FIND A POSITION IN YOUR REPERTOIRE Tap the magnifying glass beside My Repertoire and paste a FEN: ChessFlow lists every line that reaches that position, file by file, transpositions included, and takes you straight to it. While reviewing a line, "Find in My Repertoire" in the share menu does the same for the position on the board. CRITICAL POSITIONS ACROSS YOUR WHOLE REPERTOIRE In To Review, "Critical positions" now takes you through the positions you get wrong in every file, the most-missed first. It remembers where you stopped, on all your devices, and shows above the board which file and line each position comes from. YOUR PGN'S COMMENTS AND SYMBOLS Reviewing a line, you now read the comments written in your PGN - tap a long one to see it all - and symbols such as !, ?, !! and !? appear on the board, on the square the move lands on. Comments never show while you train; symbols appear once you've played the move ("Move symbols in training" in Settings). LICHESS STUDIES Studies imported from Lichess keep their study and chapter names, and each file can be grouped by opening or by study chapter. A MOMENT ON THE FINAL POSITION On the board on screen, a finished line now stays on its final position, arrows included, until you tap "Show result". You can turn this off in Settings. AND ALSO - Each file can open its lines at the start or at the final position: "Open lines at" in the file's ⋯ menu. - A line's options now open with a long press on it, and scrolling the PGN is never blocked. - Lines with the same name are now told apart. - With large text sizes, the move list and the Training button no longer overlap. - Turning on the engine no longer makes the board jump. - Your training reaches your other devices sooner, the app starts faster, and To Review opens without a pause.

LET CHESSFLOW PRESS YOUR CLOCK Playing the computer, ChessFlow can now press a real chess clock for you: ChessTools, our free clock app, on your iPhone. ChessFlow presses for the computer - or for both sides, if you prefer. Turn it on in Settings > Clock, with both devices on the same Wi-Fi or the iPad on your iPhone's Personal Hotspot. SORT YOUR REPERTOIRES Give each file a category - Main, Secondary, Rapid, or any name you like - and filter your library to one category at a time. It is only a label: a secondary repertoire comes up for review just as often as your main one.

GET AHEAD ON TOMORROW When today's reviews are done, a new button shows how many lines are due tomorrow and lets you review them now. They count as tomorrow's reviews, so tomorrow's list is shorter. CLEARER LINE NAMES A line keeps the name its author gave it: the move where a branch splits off is added after it, instead of replacing it. And when several lines in a group carry the same name, as course exports often do, each one now shows the move where it differs from the others. SMOOTHER SCROLLING The swipe actions on a line now start only from its right edge, so scrolling through a long list is no longer mistaken for a swipe.

Fixes and refinements. - Reviews now always open with the right colour already selected, and start on their own as they should. - Hidden lines are easier to spot: a block's heading now shows how many of its lines are hidden. - Groundwork for a sync issue where two devices could disagree on how many lines are due today.

The biggest update yet. A NEW ENGINE Stockfish 19 now runs inside ChessFlow, built for Apple silicon and several times faster than before on both iPhone and iPad. When you analyze a position, a slim evaluation bar sits beside the board, with markers at one, two and three pawns, so you can see who stands better at a glance. SHARPER PIECES All 18 piece sets are now vector art: crisp at every size, on every device, the default included. A new Licenses & credits panel names every author. KNOW WHAT IS COMING A bell on the finished-training screen takes you straight to your next review. Tap it and you see the next seven days - how many lines come due each day, counted right now - so you know when a backlog clears instead of guessing. The forecast stays on screen even when you are done for the day. And when you finish the last review of the day, the app says so. MORE CONTROL OVER SINGLE LINES Swipe a line to reset just that line's progress, leaving the rest untouched. Mark the lines you have already studied elsewhere: it is a note to yourself, and it never affects your scores or your review schedule. EASIER TO TELL LINES APART Previews of sibling lines now start where the lines actually diverge, instead of repeating the moves they share. FIXES The first review of the day no longer opens without a color selected, and starts on its own as it should. Manual line order now syncs between your devices, and two files can no longer overwrite each other's order. Scrolling a long PGN is no longer interrupted by the swipe gesture.

A round of fixes and refinements. Getting started is smoother: the first run now takes you somewhere, and the setup screens read properly at every text size. Large PGN files open much faster, and very large game archives are flagged clearly instead of slowing the app down. Plus smaller layout fixes on compact screens and at large text sizes.

Your daily review list now holds still. It is decided once, at your reminder time, and no longer grows while you work through it: lines you finish come off the list, and nothing new appears until the next day. On small screens, the page of a line now scrolls when it needs to. The training buttons stay reachable at any text size, including the large accessibility sizes.

More room on small screens. On iPhone SE, opening a line left the training buttons below the edge of a page that does not scroll, so there was no way to start. The move list is shorter there now, the board keeps its full size, and White, Black and Play vs Computer are all within reach. The guide is clearer about hints: on a Chessnut board the destination square lights up, and on the board on screen it is highlighted.

Small screens are welcome again. On iPhone SE and other short screens the home screen now fits, so loading a PGN or importing a folder is right there instead of below the edge. Import from folder: you can search for a repertoire and still see the button that adds it. Search, tick, add. Your library also marks a file with its source and its attachments the moment you set them, without waiting.

Your repertoire stays put. Edit a PGN outside ChessFlow - add a line in another app, or take one out - and the file keeps the colour you play it as, and stays in the section where you filed it. When a critical position will not come to you, you can now ask to be shown the move. Play it yourself and carry on, instead of leaving the session to get past it. The library also shows at a glance which files carry a source, so you can see what you have filled in without opening them one by one.

ChessFlow now explains itself. A new guide, "How ChessFlow works", covers how a PGN becomes lines, why a line comes back for review, and what the drill actually practises. You will find it behind the (i) on the home screen, or as the first row of Settings. A repertoire file can also record where it came from - the course, book or coach, with a link when there is one - and hold two attachments instead of one.

Resetting the progress of an opening now really clears it, on every device you use. Scores, training dates and critical positions for those lines start from zero again, and stay that way.

You can now hide a line you do not want to train. Hidden lines disappear from your repertoire and are never brought up for review, and you can bring them back at any time with their progress intact. Your PGN file is never modified. Your training progress now stays in step across your iPhone and iPad.

Nothing to review? You can now practice a random line from your repertoire, right from the review screen. The daily reminder is clearer, and no longer shows a count that could be out of date on a device you had not opened in a while.
