My role

Everything

The problem

A workout journal for planning and logging sessions. The bar for this kind of app is not features, it is speed: if writing down a set takes longer than the rest between sets, people stop doing it and the data stops being worth anything.

How it works

• The screen you need mid-workout is one tap away, never two.
• Planning and logging use the same model, so a planned session becomes a logged one without re-entering anything.
• Built in Flutter during the exchange semester, which is where I learned how much of an app's feel comes from the transitions between screens rather than the screens themselves.

Stack

Flutter, Dart.

What I take from it

A small app with one job, which made it a good place to be strict about that job. Everything that did not serve logging a set faster got cut, and the app is better for what is missing from it.

Outcome

University project, 2024.
