Overview

JAWKU Speed is a wrist-worn sensor that times athletes’ sprints and agility drills. The app is where athletes pair their sensor, run drills, and track how they’re getting faster, down to the hundredth of a second.

I designed the entire app experience, from the architecture and wireframes through the final iOS and Android UI. The sensor hardware and the JAWKU brand were provided by the client.

01The app

Your phone is the finish line

The app offers three ways to test: Speed, Agility, and Build-a-Drill. Athletes pick a distance and a start type, and their phone becomes the finish line.

02Architecture

Mapping the whole app first

Before any visual design, I mapped the full app in annotated wireframes: onboarding, sensor pairing, the four main tabs, running a drill, and the Build-a-Drill flow.

03Onboarding

Getting athletes in quickly

Athletes sign up with email or Facebook, then can add details like date of birth, height, weight, and sport, or skip ahead.

04Sensor pairing

Pairing the JAWKU Speed

Pairing walks through searching for, finding, and naming the sensor, with a clear path to search again when no sensor is found.

05Connection status

Always know if the sensor is connected

The sensor’s connection lives at the top of the app. Pulling it down shows which sensor is connected, the app returns to searching if the sensor drops, and firmware updates are announced in-app.

06Running a drill

Setting up the photo finish

Before a run, a short walkthrough shows how to line the phone up with the finish so the front camera can stop the clock. Results show run time to the hundredth of a second and reaction time to the thousandth.

07Splits

Every split, not just the total

Longer drills break into splits. Athletes can view the full run or select any single split and compare it against their best.

08Track

Progress over time

Track lists each drill with its best time, and trends can be viewed by day, week, or month. Beating a record triggers a New Record animation.

09Build-a-Drill

Athletes design their own drills

Athletes build a drill by choosing a distance, the number of splits, and a start type (movement or an audible three-beep start), then naming it. Saved drills can be duplicated or deleted.
