Tap Inn, A Golf Coaching App That Ships Every Week

3platforms built and maintained iOS, React Native & web admin

Nick came to us with a coaching idea and no engineering team. We became that team, building and running three codebases in parallel: a native iOS app, a cross-platform React Native app, and a web admin for coaches, on a Firebase + Stripe backend. We ship on a steady weekly cadence and report every change back to the client.

Timeline: Ongoing retainer
Team: 1 iOS Engineer, 1 React Native Engineer, 1 Full-stack Engineer

The challenge

Golfers improve fastest when a coach can see the swing and respond to it. But the feedback loop is broken: lessons are expensive, in-person, and impossible to review later. Nick wanted to close that gap in an app, letting a player capture a swing on the range, hand it to a coach, and rewatch annotated feedback as many times as they need. Doing that well meant smooth video capture, reliable delivery, in-app payments, and a coach-side surface to manage it all, across iOS and cross-platform, with a solo founder footing the bill. He needed a product team that could move fast and keep him in the loop, not a black box.

What changed

3 codebases: iOS, React Native, and coach admin
Weekly: Ship cadence, reported monthly
1: New admin app built from zeroin a single month

They run my whole product like it is their own. Every month I get a clear report of exactly what shipped, and the app keeps getting better without me having to manage engineers. It feels like having a full team on call.

Strategy

We scoped the smallest version that delivered the core loop, record, send, coach responds, rewatch, and sequenced everything else behind it. A monthly written report to the client keeps priorities honest.

Design

A calm, sport-native interface. a guided first-run tutorial, a focused capture flow, and a rewatch view built for studying a swing rather than just playing a clip.

Build

Three codebases in step. native iOS (Swift), a React Native app (Expo), and a Vite/React coach admin, on Firebase (auth, Firestore, cloud functions, messaging) with Stripe for payments and push for the feedback loop.

Grow

We ship weekly and measure the work. changes shipped, screens delivered, hours invested, sent to the client every month so the roadmap reflects what actually moves the product.
