Tune-Up

The product

Tune-Up is a personal training log that turns raw workout entries into actionable weekly summaries. Instead of manually comparing spreadsheets, users open the app and see how this week compares to the last — volume, consistency, and progress across sessions.

• Workout logging with per-session detail
• Automatic weekly summaries and progress view
• Mobile-first experience built for quick entry between sets

The tech

Built with React Native and Expo in strict TypeScript.

My role

Solo mobile engineer

I own the project end to end: product definition, data model, UI, and release tooling.

• Product and UX decisions
• React Native / Expo implementation
• Data model and weekly-summary logic
