Hello, I'm Carlos.

Hello, I'm Carlos.

Leafscan started with a phone call from my brother. He was spending countless hours measuring leaves with an expensive, bulky machine during his plant physiology degree. Shouldn't there be an app for that?


As a software developer with a keen eye for usability, I knew I could build something better: precise, practical, and designed around how researchers actually work.


I hope Leafscan makes your work a little easier. I read every review and email, so please don't hesitate to reach out.
