March 2026: Het Financieele Dagblad, the Dutch financial daily, on Philip, Louis and the math app they built before colino · Read the article →Without this app, we probably would have hired her a tutor. I’d highly recommend it to other parents and kids.
I love your app. It really helped my grades and makes math so much easier. Thank you!
Take photos of your textbook, and lino, your personal tutor, walks you through the lessons and practice problems.
Kids learn best with one-on-one help. But a teacher with 30 students can’t give each one that kind of attention.
We’re Philip and Louis. We studied math at TU Delft, the top engineering university in the Netherlands, and we’ve tutored students for years. With one-on-one lessons, we could only help a few students at a time. So we built our first app, and now colino, to give every student a personal tutor.
We’re starting with math because it’s where students get stuck most: miss one step, and everything built on it falls apart.
colino is in beta, and until Saturday you can get your child a free spot for a month. Sign-up closes in 37h 26m 02s.
