SwimPass

SwimPass answers the question open-water swimmers ask every morning: is it safe, is it worth it, where exactly do I get in. It is a Next.js application on Supabase that I designed, built and run, with a database of more than 59,000 spots worldwide, a conditions pipeline from public weather, tide and water-quality feeds, a personalised score, Strava sync and paid subscriptions.

The native iOS app puts the same conditions and score on the wrist, records the swim on Apple Watch without a network session, and lands it in the log once, however many times the watch delivers it. The building is done; the work now is distribution and data quality.
