PaceLog
Running & Fitness App
PaceLog is a running log that treats honesty as the first feature: the numbers a run actually produced, typeset to be read at arm's length, on a phone designed for afterwards and a watch designed for mid-stride.

The Challenge
Honest before motivating
Fitness apps have drifted from recording runs to managing runners — streaks that scold a rest day, badges for behaviour the product wants, and a home screen that reads like a report card. The result motivates briefly and then gets deleted, usually in winter.
PaceLog began from the opposite premise: a log a runner still trusts in February. That meant recording what happened without editorial, and spending the design effort on making those numbers legible in the two contexts that matter — mid-run at arm's length, and afterwards on the sofa.
The Approach
How we worked
During and after are different products
The watch face was designed for a moving reader — heart rate and progress, nothing more — and the phone for the sofa afterwards, where the route and splits reward a longer look.
Typeset for arm's length
Distance, pace and time are set at a size chosen by testing at a stride, not at a desk. If a number needed a squint, it was set larger.
Record, never editorialise
A rest day is a blank space, not a broken streak. The log states what happened and declines to have an opinion about it.
The week is the unit
The summary chip counts kilometres and runs across the week, because consistency is the thing a runner can actually control.
The Solution
The run, stated plainly
A finished run opens on its three numbers — distance, pace, time — set large enough to be read without ceremony, with the GPS trace and the kilometre splits beneath them as evidence rather than decoration. Nothing on the screen congratulates or scolds; the run simply is what it was.
On the wrist, the paired face carries only what mid-run eyes can use — heart rate and a progress ring, coral on near-black for contrast in early light. The week gathers into one quiet chip of kilometres and runs, and that chip is the product's whole opinion on motivation: keep showing up.
Inside the product
What it actually does
Every Screen
One product, whatever it is opened on
The phone layout is not the desktop one squeezed down. Density, hit areas and reading order are decided per screen, and the interface keeps its meaning at both ends.
Capability
What we brought to PaceLog
The same services are available on their own — each one links to what it involves, how it runs and what you get.

The Outcome
What it settled
- The log records the run without judging the runner
- Numbers legible at arm's length, sized by testing at a stride
- The watch carries the during; the phone carries the after
- Weeks framed around consistency rather than records
