1. Step-by-step audio notifications once you have reached your required speeds. 2. Speed data filtering. Readings with the filter on are more inert than those with the filter off though. THE FILTER MUST BE ON WHEN CYCLING, JOGGING OR WALKING. 3. The G-meter. Get APPROXIMATE acceleration calculated based on your speed variation. Why use the GPS G-meter: no need to keep your iPhone in a fixed position or connect it to your vehicle’s computer system, which means speed readings can be taken discreetly, for example, during a test drive. Taking a number of readings compensates lesser accuracy. Acceleration is calculated only when the filter is off. Acceleration cannot be measured near tall buildings, in the mountains or woods. 4. Large, well-lit digits 5. HUD (the speed is displayed in the windscreen reflection at night time or in cloudy weather) 6. Background mode. Continued use of GPS running in the background can dramatically decrease battery life. 7. Speed and acceleration graphs 8. Odometer 9. Altimeter 10. Time, journey duration, and current stop duration. The current stop duration will be reset after 20 seconds of motion. 11. See tracks on the map 12. Save tracks 13. Compass 14. Angle of incline (inclinometer) 15. Aircraft descent/climb angle 16. Get detailed stats for any part of your journey 17. Export your journey to a KMZ or GPX file 18. Export track statistics table to a CSV file 19. Load and show your route (journey plan) on the map together with a track. To do this, create a route, using a special online service (such as GPX Editor - https://www.gpxeditor.co.uk/map, The online GPX file editor - https://gpx.studio/, Track drawing websites - https://wiki.openstreetmap.org/wiki/Track_drawing_websites) on your desktop, and export it as a GPX (KML, CSV) file. The file name must begin with "Route". Using iTunes, transfer the file into the app (OR use the "Files" app). Following this, you will be able to select your route at the bottom of your track list. Now you can easily travel following your route line, even without loading a map. 20. Export and import files via iTunes and email 21. Waypoints (description, color selection, keywords, photos, audio records) 22. A single waypoint database with a filter option 23. Music controls 24. No annoying ads 25. Vintage design Audio alert settings: • "60! 70!! 80!!!": One audio signal once you go over 60, a continuous signal for over 70, and another continuous (and more unpleasant) signal for over 80. • "60! 70": Detailed cues, such as "60! 70!!". • "50!! 55. 60!!": Continuous signal within the speed range between 50 and 55, and continuous signal for over 60. • "60!!! 60.": One signal above 60. • You can enter a comment at the beginning of the line, for example, "Highway 70!!!". • Type in any word without numbers (for example, "OFF") and use if to turn off the speed control. • You can upload your own WAV file with the name of the signal (for example, "!.wav" or "!!!.wav") to play your own sound. Connect your iPhone to a computer, then go to iTunes > iPhone > "File Sharing" > Apps. Or use the "Files" app. IMPORTANT! 1. When driving past tall buildings (or in the mountains or woods) with the filter off, the device may display false speed spikes (due to an unstable satellite signal). In this case, switching the filter on may be a better option. 2. Car speedometers often display a higher than actual speed, the difference sometimes reaching 10%. This is due to your wheels’ diameter. This is why at high speeds GPS speedometers can deliver better accuracy than your regular car speedometer. And the higher the speed, the more accurate your GPS speedometer is. 3. Please note that temporary false readings are possible with ANY GPS speedometer when you start using it. 4. Battery life (iPhone 5S, poor light outside, 100% => 20%): Background mode (iPhone asleep): ~ 9 h Speedometer (speed, distance): ~ 4 h Track-enabled map: ~ 2 h 30 min https://youtu.be/92TefSsz7gY
