Our apps
Sharp Studio: Focus
Train attention in 5 minutes
Five short exercises — memory, attention, rhythm, breath. Five minutes a day, no streaks to guilt you, no account to make.
Chimp Test
Numbers flash on a grid and vanish. Tap them back in order. Each round adds one more.
Schulte Grid
Find 1 to 25 in order, as fast as you can. A grid, a stopwatch and nothing else.
Ink Trap
The arrow points one way and sits on the other. Go with the arrow, not the place.
Silent Beat
A dot circles to a beat, then the beat stops. Keep tapping it.
Breathing Bloom
Follow the bloom through box breathing or 4-7-8. Just a shape to breathe with.

Symmetry Studio: Mandalas
Create beautiful mandala art
A symmetry-based drawing app. Every stroke is mirrored as you draw — 12-way symmetry and a set of patterns to build from, so one line becomes a finished mandala. For artists, meditation and sacred geometry.
