The story

Tambour is an experiment from Montréal. I build the private apps I always wanted, with a lot of help from AI.

I have kept track of myself for most of my life. What I ate, what I weighed, how I was feeling that week. It started in notebooks, moved to spreadsheets, and then spent years scattered across apps that came and went.

When one of those apps shut down, got sold or raised its price, my history was either stuck inside it or gone. Almost none of them worked properly with Apple Health either, which is where all of this should come together. So I started building my own.

An experiment

I build these apps largely by vibe coding: I work with AI to get from an idea to a finished, polished app much faster than I could on my own. I find it exciting, and I want to see how far it can go.

It works because the apps are built on open standards: Apple Health for your data, plain files you can open anywhere, and open nutrient data such as the USDA and Open Food Facts tables. Your data stays readable outside my apps, so if one of them stops working for you, you can take everything with you.

What every Tambour app promises

There are no accounts, no ads, no tracking and no analytics, and nothing goes through servers of mine. Your data stays on your device and syncs through your own iCloud, and you can export all of it as a plain file at any time.

The apps also share an idea: the long view. Patterns over weeks, months and years tell you more than any single day.

Say hello

Tambour is a work in progress and I am figuring it out as I go. If you have a question, a bug or an idea for what to log next, I’d love to hear it: hello@tambour.dev.
