About
90 Day Transformation is a documented attempt, not a promise. One person, one 90 day challenge, published day by day — including the days that go badly.
Why this exists
Most fitness apps sell a result. This one records a process. The challenge started because tracking scattered across notes, a scale app and a workout log made it impossible to see whether anything was actually working. So the whole thing was rebuilt as one 60 second check-in: habits, weight, mood, a sentence of reflection.
What this platform believes
- Consistency beats intensity. A 70% week repeated twelve times outperforms a perfect week followed by a collapse.
- Data you never look at is not tracking. Every screen answers one question: did you keep your word today?
- Honest logging includes the misses. Skipped days stay in the record; the Momentum Score is designed to survive them.
- Your body data is yours. Weight is hidden by default, photos are private, and everything is exportable or deletable at any time.
How the 90 days are run
Two or three habits are chosen up front and never changed mid-challenge. Each day is one check-in. Every seventh day is a written review: what worked, what was hard, what changes next week. Progress photos and measurements are taken on the same weekday to keep the comparison fair.
Who is running it
Arthur is running the first challenge in public from Israel, starting 18 August 2026, and building the platform alongside it. The daily updates in The Journey are the raw log — workouts, food notes, lessons and mistakes — posted whether or not the week went well.
This platform is a consistency and accountability tool. It is not medical advice and makes no health or weight-loss claims.
