Thrive
App
Summary
I built Thrive after repeated frustration with interval timers that made a simple job too complicated, were hard to read during a workout, or put basic features behind subscriptions. It is my first independently shipped product. Thrive is a native interval timer for iPhone and Apple Watch that keeps setup familiar and the active workout clear.
Challenge
Interval training happens in motion. During boxing, jump rope, Tabata, or sprint sessions, people need to see the current phase, remaining time, and round at a glance, often from a distance or with sweaty hands.
The product also had to support simple repeated intervals and fully custom routines without turning setup into specialist configuration. I chose Apple’s ecosystem to expand from product design into native development and to make Apple Watch a useful workout surface with HealthKit support.
Solution
I designed and built a native iPhone and Apple Watch app for creating, editing, and running symmetrical and asymmetrical interval routines. Familiar lists, forms, pickers, and navigation make setup immediately recognisable to Apple users.
During a workout, Thrive switches to a high-contrast timer with large type, stable controls, distinct phase colours, progress feedback, haptics, and audio cues. The app stays easy to understand when attention belongs on the workout, not the screen.
Design for a glance
The active timer makes the current phase, remaining time, and round easy to read without sustained attention. Large typography, clear colour states, and stable controls help users stay focused while training.
Keep setup familiar
Creating a routine should not require learning a new system. Users can start with presets or build custom workouts through familiar iOS patterns, from simple repeated intervals to fully individual sequences.
Make Apple Watch useful
Apple Watch is a workout surface, not just a remote for the phone. Users can start, run, and complete workouts from their wrist while recording health data when permissions allow.
