For practitioners
A self-monitoring notebook that fits in a pocket.
My name is Florian Guillot. I build Mallard alone, an Android app that started from a simple idea: self-monitoring works better when the tool doesn't judge.
Mallard is for noting, in ten seconds in the evening, what you did and how you felt. You choose what to observe (glasses of alcohol, exercise, sleep, screen time, whatever you want) and the app records it, nothing else. No streak to protect, no score. An empty day stays an empty day. Even the average only appears if you ask for it: for someone who tracks precisely to gain some distance from self-criticism, a red number can do more harm than good.
The day's mood is noted in the same place, on a five-face scale, and the history shows both together: what you do, how you're doing.
Privacy
There is no account and no server. The data stays on the phone; I couldn't read it even if I were asked to. The person can export their history as CSV and bring it to a session if they wish, or make an encrypted backup to change phones. Details are in the privacy policy.
What Mallard is not
A medical device. Mallard treats nothing: it draws on the self-monitoring records used in cognitive behavioral therapy, and replaces neither the framework nor the work. The clinical setting is yours. It's a notebook.
In practice
Mallard is on Android: see it on the Play Store. For people who prefer paper, there is also a printable self-monitoring sheet, same format, customizable online.
If you try it and something is missing for it to be genuinely useful between two sessions, write to me: contact@mallardapp.app. That kind of feedback decides what I build.
