JRun

JRun is a simple, locally-focused running tracking tool suitable for daily running training and personal workout review. You can use it to record running routes, distances, durations, pace, kilometer splits, steps, average cadence, and average stride length, and view historical runs, weekly, monthly, and yearly statistics, as well as cumulative distances from your running shoes.

JRun does not require account registration and does not offer cloud sync, social features, leaderboards, ads, a store, or a membership wall. Running data is saved locally on your device by default, but you can also actively export it as a GPX, CSV, or JRun backup file for easy saving and migration.

JRun only starts a location foreground service with continuous notifications after you actively begin running, allowing you to continue recording your run even when the screen is locked or you switch to other applications. Location and foreground services will stop after you finish or discard your run.

JRun uses MapLibre and Tianditu to display online maps. If your device does not support step counting, has unauthorized motion recognition, or has no valid step count data, step count and cadence-related metrics will be displayed as unavailable, but this will not affect GPS route, distance, pace, or run saving.

JRun is a running tracking tool and does not provide medical diagnosis, treatment, or health advice.
