GPSTest is a small Android app that shows what your phone’s GPS and other GNSS systems are doing. It can show satellites, signal strength, location details, speed, direction, altitude, and other GPS information.
The app is useful when your phone seems to have a weak location signal. It can help drivers, hikers, developers, and curious users check satellite signals.
Redmi Test
I tested GPSTest on a Redmi Android phone to see how it feels in normal use. The app opened quickly, and the main screens loaded without a long wait. Moving between the Status, Sky, and other screens felt smooth.
I did not notice major menu lag during the test. The phone stayed at a normal temperature during short use.
Battery use was reasonable for a short test. Long outdoor sessions can use more power. I did not see major visual bugs during testing.
Main Features
- Satellite Status: The Status screen shows satellites that the phone can see and the ones being used for the location fix. This makes it easier to understand why a GPS signal may be weak.
- Sky View: The Sky screen gives a simple view of satellites around your phone. It is useful for seeing which satellite signals are strong or weak.
- GNSS Support: GPSTest can show systems such as GPS, Galileo, GLONASS, BeiDou, QZSS, NavIC, and SBAS when the phone supports them. This helps you check your phone’s location hardware.
- Location Details: The app can show latitude, longitude, altitude, speed, direction, and accuracy. These details are useful when testing GPS performance outdoors.
- Map and Settings: The app includes a map view and settings for units, screen behavior, GPS updates, and display choices. The map needs Google Play Services on supported versions.
Storage and Privacy
GPSTest is a light app. Recent Android package information lists the APK at about 4.1 MB, so installed space can vary by version and device.
Basic satellite viewing can work without mobile data. Network access is listed as a permission, and some map features may need internet access.
Location permission is important because the app needs precise location access to read GNSS information. Newer Android versions also list network and foreground-service permissions. GPSTest is open source and lists no ads or trackers.
Alternative Apps
GPS Test by Chartcross is a direct alternative with satellite and signal information, but its design and feature set are different. GPS Essentials also combines GPS tools with maps and measuring features. GPSTest is a better pick if your main goal is checking satellite and GNSS information without many extra tools.
