Pulse Fit

An iOS training app that doesn't infantilise the user.

LAUNCH PULSE FIT → This is my interpretation. The button above opens the live front-end built in the product's own language.

The problem.

Every training app assumes the user is new. The market of intermediate lifters was being patronised into uninstalls.

II · Build

What I shipped.

What

A workout planner for people who already know what a deadlift is. Plates-first, reps-second, emojis never.

How

SwiftUI throughout, Metal for the rep-detection camera mode, CoreML for form-check.

Why

Respect is retention. Pulse Fit holds DAU/MAU above 40% in a category where the average is 14%.

III · Counted Representative figures. Actual client metrics are under NDA.
