Build an app people keep using.

Overview

How we approach it.

An app is judged in the first thirty seconds and kept or deleted in the first week. Getting past both takes product thinking, platform-native design and a backend that never makes the app wait. We do all three, and we have shipped through App Store and Google Play review enough times to know what gets rejected.

We build native in Swift and SwiftUI when the platform is the product, and cross-platform in React Native with Expo when one team must ship both stores and a web app from the same TypeScript. We will tell you which fits, and why, before you commit.

  • Push, maps & location

    APNs and FCM through one service, geofencing, background location done within platform rules.

SportzOS: a league platform with live scoring across seven sports

Registration, payments direct to organisers, fixtures, live scoring and standings for tennis, pickleball, cricket, soccer, basketball, volleyball and baseball, in one app and one website.

Problem
Organisers ran registration on forms, fixtures on spreadsheets and scores on group chats. Players had no single place to find a league, pay, and follow results.
Solution
A cross-platform app and web platform with sport-specific scorers, a standings engine, organiser tooling, and entry fees that go straight to the organiser.

iOS, Android, web
