You can't improvewhat you can't see.
Your life is already generating data. We build the apps that turn it into something you can actually use.
Treky
Personal Intelligence App
Your days, made visible
Goals, habits, walks — Treky turns daily life into data you can see, and data you can see into decisions you can trust.
Hylle
Library Management App
Know your shelf
Every book you own, visible at last. Track your reading, spot your patterns, and never buy a duplicate again.
Instruments for a measured life.
Treky Labs is an Amsterdam app studio built on one belief: better decisions start with awareness, and awareness starts with visibility. Businesses have run on data for decades — we bring that same clarity to everyday life.
If you can see it, you can change it.
Visibility First
Awareness begins with seeing. We make data collection so effortless it disappears — so the visibility is simply there when you need it.
Design Is the Product
Data only changes behavior when you want to look at it. We obsess over every pixel because beautiful is what makes data-driven livable.
For People and Businesses
The same idea scales. Hylle helps readers know their shelves — and is now piloting with bookstores to bring that clarity to their inventory.
Your Data Stays Yours
Insights come from your own patterns, never anyone else's — and your data is never shared or sold. Visibility for you, not about you.
Your goals, measured.
Treky turns goals, habits, and daily activity into data you can actually see — so momentum stops being a feeling and becomes a fact.

Insights from your own data

Everything logged
Every action recorded, every gain measured, nothing lost.
iOS & Android
Your data travels with you, on both platforms.
Your library, visible at last.
