Ember

Three iOS screens for a training app: a recovery score, a training block planner and editable power zones.

A design project: we designed these screens, and they were not built by us.

Overview

Ember is a design concept for an endurance training app, drawn as three iOS screens at 390x844. The first screen leads with a recovery score of 84 in an arc gauge, backed by the four readings behind it: sleep, sleep quality, HRV and resting heart rate, plus weekly load against target. The second screen plans a training block on July and August calendars, with base and peak phases marked as range pills rather than as form fields. The third gives the athlete control of their power zones, offering an automatic FTP method or a manual threshold, with five zones showing watt ranges and percentage steppers.

A score you can argue with

The recovery score gets the arc and the largest type, but the four drivers sit directly beneath it. Showing 7h 20m of sleep, 92% sleep quality, 48ms HRV and a 52bpm resting heart rate turns a single number into something the athlete can check rather than trust.

Phases as ranges, not form fields

Training blocks are marked straight onto the July and August calendars as labelled range pills, so the shape of the block is visible while it is being set.

Zones that stay editable

Each power zone carries its watt range and a percentage stepper, with the first and last steppers disabled so the ladder cannot be broken. Automatic and manual methods sit side by side, and the manual option is the one selected.
