See whether you're getting better, and drill the cards you keep missing

A streak tells you that you studied. It doesn't tell you whether it's working. Your progress page now does.

Accuracy over time. Braineos keeps every answer you give, from the web, the app or your assistant. The progress page turns them into your percent correct, with the number of answers behind it, and a bar for each of the last 12 weeks. If the bars climb, the reviews are sticking.

Cards you miss most. Below the chart is a short list of the cards you get wrong most often, each with how many times you missed it ("missed 3 of 5"). These are usually the cards worth your next ten minutes.

Drill these. One tap starts a study session of just those cards, so you can work on your weak spots without wading through cards you already know. Each deck you've studied shows the same panel for that deck alone.

It needs a little history first. Until then you'll see "Not enough answers yet to show a trend", and the chart fills in after a few more study sessions. Answers count from late October 2026, when we started keeping them.
