Rarely, but properly. What is written here is either measured or lived through — there are enough how-to articles already.

Does magnesium work for me? Find out, don’t guess

No study can tell you whether magnesium changes your sleep. Three weeks of notes, then a look back, without the app handing you a verdict.

Supplement tracker app: what actually matters

Nine criteria you can check against any supplement tracker app yourself, and an honest account of where RecTake fits and where it does not.

Switching phones: what happens to my entries?

RecTake and Cal AI: two diaries, two questions

Cal AI counts calories against a daily target. RecTake records what happened — so you can see for yourself which days went well. What each one does, and when which is the right one.

ADHD, supplements and why I built RecTake

Creatine, omega-3, fewer carbohydrates, more water — and the suspicion that it makes a difference. Why I built myself an app you only ever speak to, and that asks how you are doing by itself.
