Maps, steps and a choice of map apps

Google Play QR + Dotori GPS Tracker

Release note (5 November 2026): Step recording is not in the current Play Store release. The step-count scenes in this article and the new video preview an unreleased update. This feature will be available after that update is published.

Dotori GPS Tracker shows Korean hiking trails and contour lines on Android. Save places and record journeys, or use a large speedometer or mirrored HUD. The upcoming update adds trip step recording. When you share a location link, the recipient chooses the map app they use.

See trails and contour lines on the map

Download optional Korean hiking and contour data to show their lines on the map. Tap a trail for its name and source notes. Zoom in for 20 m contour intervals, with a thick line and altitude label every 100 m.

Download Korean place names and regional business data for offline search. Search by name prefix or Korean initial letters. A separate button runs online address search.

Save a place and check the direction back

Save your position with a note. Long-press Save location to choose food, parking, sights, shopping or your own category. Places saved while recording become waypoints in that journey.

A return compass shows direction and straight-line distance. Parking places have a My car action. Open an external map app for directions along roads.

Send the location and let the recipient choose the map

Send the location link through a messaging app. It opens a shared page where the recipient chooses KakaoMap, NAVER Map, TMAP or Google Maps. The recipient can use an installed Android map app. Its availability and terms apply.

You choose whether to include the note. Use Copy if you only need coordinates and a link.

Record your route and trip steps together

Record by time, distance or both conditions together. A trip you start can continue with the screen off. Pause, resume or finish from the app or notification.

Power saving and reception can leave gaps. The app checks for relevant restrictions before recording. The upcoming update adds Record steps to save phone-sensor step counts with the journey. A supported sensor is required; physical activity permission is requested where needed.

Pausing a trip pauses step accumulation. This counts during the trip rather than automatically throughout the day. Afterwards, review the route, distance, trip duration and moving time. Speed, ascent and steps are also shown.

Use the speedometer or mirrored HUD

The speedometer shows GPS-estimated speed in large digits. It supports a mirrored HUD, portrait and landscape rotation and digit sizes. Ads are hidden in the full-screen HUD.

The phone vibrates above a threshold you set. This is your own threshold, not an automatic reading of the road speed limit.

Put your position in a 119 message

The 119 action prepares a message with your coordinates. It adds a calculated Korean national grid reference, accuracy and fix time. Add incident details and send it yourself in your messaging app. It does not automatically send a message or confirm assistance.

Keep your records and export when needed

Coordinates, routes, notes and steps stay on your device without an account.

  • Move records and steps with a JSON backup. Restoring replaces existing records.
  • Share selected coordinates, notes and links when needed.
  • Maps and advertising providers apply their own data practices.

GPS tools show satellite reception and coordinate formats. Load a shared route, record while following it and receive vibration alerts for sustained deviation. Export your own route as GPX; steps are included in JSON backups rather than GPX.

The base map needs internet. Korean trail sources mainly date from 2016-2019 and do not show every trail or current closures. The return compass shows a straight-line direction. GPS, speed and steps depend on the device and environment.

Watch the demo for map exploration, recipient map selection, route and step records and GPS tools. Routes, notes and steps on screen are synthetic examples at public places.
