Cortiq

Cortiq is daily brain training built on one idea: the only score that matters is your own from yesterday.

Five minutes a day. Two quick exercises for speed and logic, three weekly tests for memory, focus, and processing speed. No leaderboards, no vague "brain score" — just your own trend line, going the right way or not.

THE DAILY SESSION

• Speed Arithmetic — twenty three-term problems, solved left to right. Your time and misses are the whole result. Beat 60 seconds for gold.
• Symbol Mode — thirty problems where +, −, and × are hidden behind shapes, and the mapping is dealt fresh every run. You decode before you calculate, so it never turns into rote arithmetic.

Both roll into one daily record with streaks and a gold/silver/bronze medal tally.

THREE WEEKLY TESTS
Run them once a week under the same conditions. Cortiq reports the change against your own last result — nothing else.

• Count 1→120 — count aloud as fast as you can, timed to a tenth of a second.
• Word Memory — 30 words, two minutes to learn and two to recall, in your own language.
• Stroop — tap the ink color, ignore the word. The classic focus test.

PROGRESS YOU CAN TRUST
A 30-day arithmetic trend, a four-week session heatmap, your medal count, and a full test history with deltas. Improvement shows up as a line going down.

PRIVATE BY DESIGN
Cortiq has no accounts and no analytics, and makes no network connections of its own. Your progress lives on your device and syncs through your personal iCloud, so it follows you to a new iPhone and survives a reinstall. Nothing is collected, nothing is sold.
