How much do you notice?
Get to know your senses with Percore. Four short daily exercises explore color, pitch, timing, and shape, all in about two minutes.
FOUR WAYS TO EXPLORE YOUR SENSES
• Color — Keep a color in mind, then recreate it.
• Pitch — Listen to a tone, then find the same pitch.
• Duration — Get a feel for a short interval, then press and hold to match it.
• Shape — Keep a shape in mind, then match its position, angle, and size.
FOLLOW WHAT CHANGES
See how closely each answer matches its target. Track your results over time and discover which senses stand out and how they vary from day to day.
EXPLORE AT YOUR OWN PACE
Try focused exercises in vision, hearing, timing, and spatial perception. Choose a skill to practice and return to it whenever you feel like it.
MAKE THE RITUAL YOUR OWN
Training something specific? Choose any four of seventeen modules to be your daily, in the order you like — Pitch, Rhythm, Timbre and Duration for your ear, or whatever your practice needs. Your ritual is measured every day, just like the original four.
A SMALL PART OF YOUR DAY
Four daily exercises, with a clear finish. No long sessions or complicated routines. Make a little room to notice more.
Some features and practice modules require Percore Pro.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A gentler first run: before each of the first four readings, a short rehearsal shows the control and lets you try it. No explanations to read, no timer.
We ask later, not sooner: the reminder question comes after your first completed ritual, the account question a day or two in.
Fixed: with Reduce Motion on, the second half of the Color reading could appear blank.
Fixed: opened without a connection, some screens stayed empty until a restart. They now fill in once you're back online.
