Challenge

Swimmers who want to improve keep hitting the same wall: generic training plans ignore their level, goals, and technique — and quality coaching is expensive and hard to access.

Swimmie set out to close that gap and give every swimmer a coach in their pocket: a tailored plan, feedback on technique, and the motivation to keep going.

Solution

We took the engagement from idea all the way to a finished product:

Branding & positioningWe created the Swimmie brand and a visual language that feels sporty, clean, and trustworthy.
Product DiscoveryWe mapped the needs of swimmers and coaches and defined what the first version had to do to be worth shipping.
App designWe designed the user flows and screens: personalized onboarding, the weekly plan, technique courses, video coaching, and a blog.
App developmentWe built the app end to end and took it to launch.

The result is an app that carries a swimmer from the first questionnaire to a tailored training plan, offers technique analysis, and connects them with a coach.
