**FSRS Ultimate ** shows your FSRS memory data right on the card while you review, and adds an optional space-war game that rewards what really builds long-term memory: spaced, effortful recall.

Most of the add-on is free. A few extras are paid, and they help me keep shipping quality updates. You can preview everything before you decide.

1. See your memory on every card

What you get

• Live Card Info under the card: retrievability (how likely you are to remember it right now), stability, difficulty, lapses, average answer time and deck.
• A real forgetting curve for the card you are looking at, with your retention target (90% by default) drawn on it and time ranges: 7 days, 30 days, 90 days, 1 year or all.
• Switch each widget on or off: dashboard, recall stars, review timer and the Void Fleet HUD. Keep only what helps you.
• Everything updates as you answer, with no extra clicks and no change to Anki's scheduling.

2. Turn reviews into a space-war game (optional)

What you get

• Daily missions that adapt to your recent workload, so they stay doable on busy days and on light days.
• Nemesis board: the cards you keep forgetting become bosses. Beat them on different days to clear them.
• Seven arcade modes that use your own cards. Pick your targets: due cards, leeches, mature cards, a deck, a flag and more.
• Grand Prix racing: choose a track and a car (four of each), then race rivals. Fast answers boost you, a miss makes you crash.
• 18 medals and a pilot rank to unlock as you study.
• The arcade is practice outside your schedule. It never changes Anki's scheduling, and only real reviews count toward your stats.

3. Make it look the way you like

What you get

• 56 themes with a live preview, so you see the result before you apply it (the demo shows Solarized Light).
• Accent colours, fonts and star icons to match your taste (the demo shows the Royal Purple accent).
• Export, import and reset for your settings and scores, handy when you change computer.
• Your settings and scores stay on your computer in user_files/ and survive add-on updates.

Command Center

Open it from the Tools menu, with Alt+W, or with the 🚀 button on the review screen. You will find your pilot rank, daily missions, Nemesis board, medals and the theme hangar in one place.

Free and paid

• Free: Card Info, the forgetting curve, the Command Center, daily missions and the Nemesis board, plus a preview of every paid extra.
• Optional paid extras: Themes, Games and Training can be unlocked one by one (2 € each), or all together in the full pack (3.99 €). A Patron option (10 €) is there for people who want to support the project.
• Paying is never required to use the core of the add-on, and it helps me keep the quality of the updates high.

Privacy

Everything stays on your computer. The add-on only contacts the licence service if you choose to activate a paid key.

Languages

English and French, picked automatically from Anki's language.
