## What is One Second Run?

One Second Run helps you build a running or walking habit with a simple timer that grows by one second each day.

Start with a comfortable first goal, complete today's timer, and tomorrow's target becomes just one second longer. The app keeps the experience light: no GPS, no pace charts, no account, and no pressure.

Features:
- Daily run or walk timer
- One-second daily increase
- Onboarding to choose your first start time
- Streak and history view
- Optional notes for each session
- Local reminders
- Live Activity and Dynamic Island timer display
- Settings to reset progress or choose a new start time

One Second Run is designed for consistency. Open the app, start today's timer, finish, and keep the line moving.
