Hi, I'm Lena.

At first I simply wrote the days I injected into my notes app. Only the weekday and the date, without the dose. That sounded like enough at first. It wasn't.

I actually tracked quite a lot: food, drinks, training, sleep, steps, injections, supplements, weight. There just wasn't one place where everything came together. Every number lived somewhere else, and I never had the full picture.

It was most obvious before doctor's appointments, for example for blood tests or a body composition scan. Every time I brought a pile of papers. Seeing connections or really following my progress was hardly possible like that. When was that again? Which dose was I on six weeks ago? And how was I actually feeling back then?

I wanted an app where I log what happened in a few seconds and later see at a glance how the last weeks really went. Injections and injection sites, weight and body composition, well-being, supplements and drinks, plus training, steps, sleep and protein from Apple Health and, if I want, my cycle. All in one calendar, side by side instead of spread across many places.

And before an appointment, a report I can show on my phone instead of bringing a stack of papers or telling it from memory. This is what it looks like. Tracelle doesn't interpret anything. The app puts your entries side by side; what they mean is something you discuss with your doctor.

Trace means following a track. That's exactly what the app does: it keeps the trace your therapy leaves in everyday life. Elle is French for she. I built Tracelle as a woman, and topics like the cycle simply belong in it for me. Of course Tracelle is for everyone who wants to document a therapy.

Tracelle is still young, and I keep building it with every piece of feedback. If something is missing or you have an idea, write to me at hallo@tracelle.app. I read every message myself.
