Two exercises. Same time every day.
Speed Arithmetic
Twenty three-term problems. Left to right, no scratch paper. Your time and misses are the whole score.
Symbol Mode
The operators are replaced by shapes — dealt fresh every run. Thirty problems that force you to decode before you calculate.
One trend line
Both exercises roll into a single daily record, compared only to your own past sessions.
Three checks you can't fool
Run them once a week under the same conditions. Cortiq reports the delta against your own last result — nothing else.
Your only competitor is last month
Every session feeds one chart, one streak, one medal tally. Improvement shows up as a line going down — or it doesn't.
Free. All of it.
Both daily exercises, all three weekly tests, your full history. No subscription, no ads, no locked charts.
