When reporting a problem, please include your device model, OS version, app version, and whether Demo mode is on or off. Do not include passwords or access tokens.

How it works

Your microcontroller with GPS + SIM reads its position roughly every 15 seconds and, when the position changes, sends it over GPRS to your own Node.js server, which records it. Esp Track reads that data from your server (or from the log file written by the MCU) and draws it on the map. The app itself never uses your phone's GPS.

Getting started

  1. Open the app — it runs in Demo mode by default, with simulated location data and no server required.
  2. Go to Settings and enter your own server base URL.
  3. Turn Demo mode off. Your device starts appearing on the map.

Frequently asked questions

Do I need a GPS tracker device to use the app?

To see real data, yes — Esp Track is a viewer for your own hardware and server. You can explore every screen without any hardware using Demo mode.

Do I need a Google Maps API key?

No. The map uses OpenStreetMap-based tiles and requires no API key or account.

The map is empty or the device never appears.

  • Confirm Demo mode is off and the base URL in Settings is correct, including http:// or https://.
  • Open the same URL in your phone's browser — if it does not return data there, the problem is on the server side.
  • Check that your server is reachable from the internet, not only from your local network.
  • Confirm the MCU is powered, has a SIM with data, and has a GPS fix (a fix outdoors can take a few minutes on first start).

The position is stale or updates slowly.

The MCU only transmits when the position changes, so a stationary device produces no new records. Poor GPRS coverage or a weak satellite signal also delays updates. Check the satellite count and signal level shown in the device status.

How much route history is shown?

The last 100 location records are drawn as a trail on the map. Longer-term history depends on what your own server retains.

Who can see my location data?

Only you. The data lives on your own server; we operate no backend and receive nothing. See the Privacy Policy for details.

How do I delete my data?

There is no account to delete. Uninstalling the app, or clearing its data in your device settings, removes everything it stored locally. Records on your own server are deleted by you.

Requirements

  • iOS 15.5 or later.
  • An internet connection.
  • For real data: an ESP/MCU GPS tracker and a reachable Node.js server or log file endpoint.
