ZZZ GPS Simulator

ZZZ GPS Simulator turns a route you draw on a map into a timestamped GPX file and
plays it back at the speed you choose. Built for developers and testers who work
with location.

WHO IT'S FOR
- Developers and QA who need to test location-aware apps
- iOS developers who want a GPX file for Xcode's "Simulate Location"
- Anyone who needs speed-based movement logs for walking, cycling or driving

KEY FEATURES
- Tap to build routes: add points on OpenStreetMap and draw the path
- Two drawing modes: "Straight" connects your taps directly; "Road matching" snaps
the path to real roads via the OSRM routing service
- Flexible speed: walk / bike / car presets plus a continuous 1-120 km/h slider
- Round trip: automatically appends the return leg after the outbound route
- GPX generation: passing times (ISO 8601) are computed from distance and speed;
long segments are interpolated to ~1-second steps for smooth playback
- Share or save: export the GPX as text or store it on the device
- Save routes: name, save, reload and delete your routes (stored on-device)
- Movement simulation: play / pause / stop a moving marker along the route
- Mock location: while simulating, the position is exposed as the device's mock
location so other location apps can use it
(requires selecting this app under Settings > Developer options > Select mock
location app)
- My-location button: recenter the map on your current position

NOTES
- The mock-location feature requires Android's "Select mock location app" setting.
- Road matching uses an online routing service (OSRM) and needs a connection.
- Maps are rendered with OpenStreetMap tiles.
- Intended for development, testing and educational use. Please comply with each
service's terms and with the laws of your country.
