Repstack allows you to build and save your own workout routines using customizable time slots. For each individual time slot, you can set a workout title, a repetition (or distance) goal, and a time in which to complete the exercise. All exercises together form your workout, which you can then play back to you. In the playback mode, Repstack will guide you through your workout using visual and auditory cues, enabling you to focus on your workout!

We created Repstack for Android and iOS smartphone users, using Flutter to cut down development time. This also meant that we had to create a single UI/UX that felt comfortable for both platform users. Applying Material Design principles and adding FontAwesome icons we created a light yet active user interface with an experience that feels natural on both iPhone and Android phones.
