GPS Speedometer Premium

If you notice that the app shows a slightly lower speed than your dashboard, this is completely normal. If the signal is strong and stable, your GPS speed is often closer to reality. • In many regions around the world, vehicle manufacturers are prohibited from building speedometers that underreport your speed. To ensure you don't accidentally get a speeding ticket, speedometers are calibrated at the factory to read slightly higher than you are actually traveling. • Variations can also result from factors like tire size, pressure, or wear affecting the vehicle's calibration. • The app calculates your speed based on satellite positioning over time and provides an independent of vehicle calibration measurement.

GPS Speedometer Premium relies solely on the GPS sensor to provide accurate speed readings. Other apps may show your location using Wi-Fi or mobile networks, which are helpful for a faster location fix and indoor positioning - especially when GPS signals are blocked by ceilings or buildings. However, this network-based data lacks the precision needed to calculate speed accurately. To ensure reliable results, speed is only displayed when a strong GPS signal is available. Having Dual-Frequency GPS and Assisted GPS greatly helps. More information is available at https://www.gps.gov/gps-accuracy-0

Mobile devices are not professional-grade GPS devices. The app can only be as accurate as the data your phone's hardware provides. Having Dual-Frequency GPS and Assisted GPS greatly helps. More information is available at https://www.gps.gov/gps-accuracy-0

Because GPS measures your location, not your instantaneous speed. A single location point isn't enough to determine how fast you are going - the app needs to measure how your position changes over time. To calculate your speed, the app uses a simple formula* (Speed = Distance / Time): • Distance: It compares your current location with your previous location. • Time: It measures the time elapsed between those two points (typically about one second). Because of this process, the number you see on the screen is actually your average speed over the last second, rather than an exact, real-time snapshot. Additionally, you might notice a slightly longer delay if the GPS signal is weak, lost, or obstructed. * This is a simplified, general explanation. In reality more happens behind the scenes, such as taking into account Doppler measurements from GPS satellites.

This warning appears when the app detects that your device's speed accuracy (the estimated margin of error provided by your phone's Android system) is low. The warning may appear from two, different reasons: 1. The accuracy value is constantly fluctuating This is normal behavior for a weak GPS signal. Your device is struggling to get a highly precise GPS lock, indicating that a clear path to GPS satellites is unavailable. Consider moving to a more open area if possible. You can also increase the tolerance threshold in the app's Settings, or disable the warning completely. 2. The accuracy value is stuck on the exact same number If the accuracy number is completely frozen but your speed is still updating normally, this points to a software bug in your specific phone's firmware. The device is sending the app a placeholder value instead of properly calculating your speed accuracy. Because the app cannot read the true accuracy data from your phone, your only option is to disable this warning entirely in the app's Settings.

Because GPS calculates your position based on satellite signals, your determined location is rarely perfectly still - it actually drifts slightly within a small radius. When you first start the app, your phone is still calibrating its connection to the satellites. Until you move a short distance (roughly several dozen feet/meters), the device may struggle to distinguish between actual movement and signal noise. All GPS devices have a specific horizontal accuracy. If your "location" jumps to the left and then to the right, the app's formula (distance/time) interprets that jump as movement, resulting in a low speed reading. If you are near tall buildings, under a bridge, or even under heavy tree cover, satellite signals can "bounce" off these obstacles, causing your reported position to skip around even more erratically. Usually, simply driving for a minute allows the hardware to calibrate itself and filter out this noise. Having Dual-Frequency GPS greatly helps.

Speedometer and navigation apps usually drain your battery faster than regular apps. The app must keep your phone's physical GPS hardware actively communicating with satellites every single second of your trip. Also, during the day, the car interior is generally well lit, requiring higher brightness of your screen than usual. To minimize battery drain, consider manually lowering your phone's screen brightness. As a last resort, you may enable Battery / power saving mode in your device's system settings, but please note that this will generally greatly reduce GPS accuracy.

GPS Speedometer Premium is not compatible with Android Auto. Currently, Google only allows specific categories of apps - such as navigation, media, and messaging - to be integrated with Android Auto. Speedometer apps do not fall within the supported categories and are therefore not eligible for Android Auto compatibility. While it's technically possible to adapt the app for Android Auto, the strict rules and limitations would demand significant changes to its design and functionality. Ultimately, it would need to operate much like a full navigation app - displaying a fullscreen map with only a small speed indicator - which goes against the main purpose of the app.

All purchases are handled via Google Play. As such, refund requests are recommended to be made directly through Google Play and are subject to its policies. For more information on refunds and how to request one, please refer to Google Play Support page and Google Play's refund policy.

Sometimes there is a slight delay in processing the transaction. Try the following steps: 1. Verify that you received the order receipt in your email inbox. 2. Check your internet connection. 3. Completely close and restart the app. 4. Try restarting your device. 5. Ensure you are logged into the correct Google Play account. If the issue persists, please contact the developer directly via email.

Your purchases and active subscriptions are tied to your Google account, not your physical device. Purchases are restored automatically when you open the app, as long as you are logged into the same Google Play account you used to make the original purchase. If there are any issues, please make sure you have internet connection and verify that you installed the app via the same Google account. If the issue persists, please contact the developer directly via email. If you are using Premium+ Navigator, please note that you may lose all saved trips, in a case where Android's default backup feature fails. Before wiping data on your old device, please manually backup your trips by heading to Trips Panel, clicking settings icon, and clicking Backup. Select Google Drive as destination. You can now restore trips on your new device by following same steps, clicking Restore and choosing the backup file.

If you wish to cancel your subscription, you may do so in the app settings, or by heading directly to the subscriptions page in the Google Play Store application.
