Memorize your ranges until they're second nature. Forge reheats each one at the right moment so every decision sticks — no more hesitation, no more spots leaked to a range slip.
Make the decision in a full spot, hand by hand, like at the table. With your account, you train on your own ranges.
Always the same cycle: the app tells you what to review, you train, your ranges sink in a little more. A range "heats up" when you master it, "cools down" when forgetting looms.
No need to choose: spaced repetition spots the ranges you're about to forget and serves them first. You open the app, your session is already ready.
You rebuild each range from memory. Every right answer heats it up — and pushes its next review further out. The better you know it, the less you see it.
The next day, the loop starts again with the day's ranges. It's this consistency that turns effort into lasting memory.
More than a quiz: the app picks what to review, locks in each new range in three steps, then has you replay it until you hit 100% mastery.
Spot where each action goes, zone by zone.
The grid fades — you trace over it.
It vanishes: you redraw it solo, until flawless.
Forge runs on spaced repetition, a memory technique proven ever since Ebbinghaus mapped the forgetting curve: maximum retention for minimum time.
Without review, you forget most of what you learn within days. That's true of everything — including the ranges you studied so carefully.
Revisiting a range just before you'd forget it resets your memory and pushes forgetting further out each time. Forge schedules every review for exactly that moment.
Rebuilding a range from memory anchors it far better than rereading it. Every quiz is active recall — the effort that turns knowledge into instinct.
Everything you need to turn a range you read into a decision you make without thinking.
A smooth 13×13 editor — or import what you already have in seconds: Range Manager (.rm), text notation, JSON, even a screenshot of a grid, rebuilt for you by pixel analysis.
Rebuild your range from memory (13×13 quiz) or call the shot in a full spot, just like at the table. Every mistake flagged on the spot so you fix it right away.
The algorithm reschedules each range right before you'd forget it: lasting recall in a few minutes a day, without revisiting what you already own.
Mastery rate per range, streaks, trends and weak hands to revisit: you always know what to work on first — and you see your progress in black and white.
Calculators and a hand replayer to decide right and improve faster, alongside your training.
Knowing a range is one thing. Having it as a reflex at the table is another. Forge exists to close that gap. We turn what you review into instinct, one range at a time.
One training loop for every format. Create folders by format and by situation — the loop adapts to each one.
Step-by-step guides, a glossary, strategy articles and tools — all freely available.
