## What is JRun?

JRun is a lightweight iPhone running app for personal use and everyday runners.

It focuses on recording a run clearly. There are no social feeds, ads, shopping, rankings, account requirements, cloud sync, or subscription walls. Start a run quickly, then review your route and training data in a focused interface.

Features
- GPS run recording with route, distance, duration, current pace, and average pace
- Lock-screen and background location recording during an active run
- Interrupted-run recovery from the last valid local checkpoint after an app crash, system termination, or phone power loss
- Current weather before a run, with Open-Meteo as the primary source and MET Norway as fallback
- History filters for time, distance, and shoes
- Redesigned run details with an immersive map and pull-up panel for routes, metrics, notes, and weather
- Kilometer splits with exact pace and fastest/slowest labels when at least two complete kilometers are available
- Elevation chart by distance with cumulative elevation gain
- Steps, average cadence, and average stride when motion data is available and authorized
- Shoe management with automatic linked-run mileage, suggested replacement distance, and approaching/reached reminders
- Local GPX / CSV export and full run-history CSV export
- Full local JRun backup export and manual merge import for moving data
- Interface languages: Simplified Chinese, English, Traditional Chinese, Japanese, Korean, Spanish, French, and German
- Metric units only

Data boundary
JRun does not provide account registration, cloud sync, or automatic multi-device sync. Run history, shoes, profile data, and settings are stored locally on the device. Export a JRun backup before deleting the app, clearing local data, or changing phones.

Weather requires network access. Run recording can continue when weather is unavailable.
