I designed and built Gyma, a personal workout tracker that turns complex training data into a calm, session-first experience. From live logging and rest timers to progression, history, and cloud sync, the product reduces friction in the gym while keeping every set measurable and meaningful.
The Challenge
Most workout apps either drown users in features or break the flow mid-set. Between sweaty hands, short rest windows, and the need to compare previous loads, logging becomes a second workout. The objective was to design a tool that stays out of the way during the session, then becomes precise and insightful the moment the workout ends.
The Approach
I structured the experience around the live session: previous set as default, one-tap completion, rest timer as a horizontal countdown, and a persistent bar that keeps the workout reachable from anywhere in the app. Everything else — programs, catalog, progress — supports that core loop instead of competing with it.
The interface uses a restrained palette — chalk, ink, and a single accent red — with condensed display type for hierarchy and mono details for measurable data. The result feels athletic without looking like a generic fitness template: calm enough for long sessions, sharp enough to read under gym lighting.
Role
End-to-end ownership: I defined the product, designed the experience, and built the working app as a solo side project.
Outcome
Gyma is a working product, not a concept deck. The main achievements include:
