## Screenshots
## Features
* __Tracking:__ track your sport and outdoor activities
* __Voice announcements__
* __Photos and Markers:__ mark interesting locations while tracking
* __Export:__
* export tracks either as [KMZ 2.3](https://docs.opengeospatial.org/is/12-007r2/12-007r2.html) (incl. photos), [KML 2.3](https://docs.opengeospatial.org/is/12-007r2/12-007r2.html), or [GPX 1.1](https://www.topografix.com/GPX/1/1/)
* export automatically after each recording (e.g., to sync via [Nextcloud](https://nextcloud.com/))
* avoid duplication: each exported file contain a random unique identifier (i.e., `opentracks:trackid`)
* __Altitude:__
* gain/loss via barometric sensor (internal if present or via Bluetooth's Environmental Sensing Service)
* shown in EGM2008 (above mean sea level); exported as WGS84
* __Bluetooth LE sensors:__
* heart rate
* cycling: speed and distance
* cycling: cadence
* cycling: power meter
* running: speed and cadence
* support for BLE sensor training only (i.e., without GPS) for indoor training
An overview of tested sensors: [README_TESTED_SENSORS.md](README_TESTED_SENSORS.md)
### Gadgetbridge integration
OpenTracks can be used with [Gadgetbridge](https://www.gadgetbridge.org/):
* shows statistics via notification on smart watches (requires Gadgetbridge 0.56.1 or later), and
* Gadgetbridge's GPX exporter generates `opentracks:trackid` to avoid duplication (Gadgetbridge 0.53.0 or later).
### Privacy
* __No Internet access:__ Internet is not used
* __No advertising__
* __No in-app analytics__
* __No use of Google Play Services__
__Only required permissions:__
* _ACCESS_FINE_LOCATION_: required to use the GPS.
* _ACCESS_BACKGROUND_LOCATION_: required to start recording with GPS while phone is in standby. (e.g. when triggered by Public API from an external device)
### Public API
OpenTracks includes an API for starting/stopping recording by another installed application (e.g., [Automate](https://llamalab.com/automate/), [Tasker](https://tasker.joaoapps.com), or [Easer](https://github.com/renyuneyun/Easer)).
The API can be invoked by sending an explicit Intent to start an activity.
`Package` (depends on the variant installed):
* F-Droid: `de.dennisguse.opentracks`
* GooglePlay: `de.dennisguse.opentracks.playStore`
* Debug: `de.dennisguse.opentracks.debug`
* Nightly: `de.dennisguse.opentracks.nightly`
`Class`:
* **Start a recording:** `de.dennisguse.opentracks.publicapi.StartRecording`
* **Stop a recording:** `de.dennisguse.opentracks.publicapi.StopRecording`
For testing via adb: `adb shell am start -e someParameter someValue -n "package/class"`
`StartRecording` supports the following parameters:
* Set track data: `TRACK_NAME`, `TRACK_DESCRIPTION`, `TRACK_CATEGORY`, and `TRACK_ICON` (non-localized identifier see [/src/main/java/de/dennisguse/opentracks/util/TrackIconUtils.java#L38](/src/main/java/de/dennisguse/opentracks/util/TrackIconUtils.java#L38)).
NOTE: if `TRACK_ICON` is not present, `TRACK_CATEGORY` will be used to determine the icon (localized).
* Send recorded data to another application via _Dashboard API_: `STATS_TARGET_PACKAGE` and `STATS_TARGET_CLASS`
The Public API is disabled by default to protect the user's privacy, but it can easily be enabled in the settings.

## Dashboard API (incl. map)
As of v3.3.1, OpenTracks supports custom dashboards for displaying previously recorded and live
tracks.
The reference implementation is [OSMDashboard](https://github.com/OpenTracksApp/OSMDashboard), which
presents an OpenStreetMap map (showing the current track, incl. updates). The Dashboard API is also
used by [Gadgetbridge](https://codeberg.org/Freeyourgadget/Gadgetbridge/) for displaying live track
statistics on supported wearables.
Alternatively, recorded tracks can be shared as KMZ/GPX with installed applications (
e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand)). However, this is rather
slow and does not provide updates while recording.
The developer documentation is in [README_API.md](README_API.md).
## Project history
_OpenTracks_ is based upon Google _My Tracks app_ ([code](https://code.google.com/archive/p/mytracks/)).
_My Tracks_ was initially released by Google in 2010 as [open-source software](http://google-latlong.blogspot.fr/2010/05/code-for-my-tracks-is-now-yours.html).
In 2016, [Google decided to discontinue](https://support.google.com/maps/answer/6333516) _My Tracks_ and stopped distributing it via the Google Play store in April 2016.
Then [Plonk42](https://github.com/plonk42) conducted some maintenance work until 2016, so _My Tracks_ could still be used (based upon version _Google's MyTracks_ version 2.0.6).
Plonk42's version is available [here](https://github.com/Plonk42/mytracks).
In 2019, _OpenTracks_ was forked from Plonk42's _My Tracks_ and major rework was conducted.
Rework of _OpenTracks_ included:
* removing Google's analytics code,
* removing integration into Google Drive,
* removing Google Maps integration,
* removing Google Earth integration,
* removing use of Google Play service,
* removing calorie estimation and activity estimation,
* removing support for ANT+ and Classic Bluetooth,
* adding support for Bluetooth LE heart rate sensors,
* removing Protobuf (store sensor data in SQLite columns directly), and
* removing Android Service API for other apps.
Artwork, logos and user interface remained more or less unchanged.
