[Samsung Galaxy Watch 3] parshakov:
Always-On Speed [Current Version: 5.2.0; Size: 266 KB; Price: $1; free demo version is available]

The application shows the following metrics while keeping the device awake:

• Speed in km/h, m/s, miles/h, or knots.

• Average and maximum speed for the last 60 seconds.

• Direction of movement (heading) in cardinal points and degrees (shown only when moving).

• Current time in hours and minutes.

Please read the following information before using the app:

• Swipe left to open Settings. Here you can change the unit of speed, speed limit, time format, font color and thickness, and screen orientation.

• Speed limit shortcut: tap the speed indicator once and use the bezel to set the speed limit.

• You will receive visual, audio, and tactile warnings when you exceed the speed limit. You can adjust the alert volume and vibration in Settings.

• Swipe up to change the font color to white and increase the font thickness for maximum readability under direct sunlight. Expect a higher power consumption.

• Press the Back button once to check the power consumption.

• The accuracy depends on cloud cover and your speed. The accuracy is very high when the sky is clear and your speed exceeds 20 km/h or 12 mph.

• The values are updated more frequently (every second instead of two seconds) if you use an activity tracking application on your phone (e.g., Strava or Google Maps).

• Numbers move up and down the screen once a minute to prevent screen burn-in.

• The display stays on until you quit the app.

• The app does not log your activity and does not connect to the Internet.

• This app has a Pro version and a free demo version.

Troubleshooting:

• If you cannot close the app using the Back button, press the Home button two times to get to the list of apps → Recent apps → Close all. Email the developer if this happens every time.

• Disable Samsung Health workout detection for the best, uninterrupted experience. Samsung Health → Settings → Workout detection.

• Make sure that GPS is enabled before starting the app. The app cannot enable GPS on your phone automatically. Note: do not use any power saving modes/apps on your phone because they interfere with GPS.

• If your watch has a built-in GPS, the app can use it but only if you disconnect the watch from your smartphone (for example, by disabling Bluetooth on your phone). Expect a much higher power consumption.

• Please contact the developer if you encounter a bug or if the app does not function as advertised. Feature requests are more than welcome!

There are several features that reduce power consumption:

• The rotating bezel on the Gear S2 and newer smartwatches can be used to adjust the screen brightness. Note: in bright sunlight the brightness level locks at 100% and cannot be adjusted.

• Green font uses half as many sub-pixels as white font, resulting in lower power consumption.

• If you stop moving, the device will start vibrating once a minute so that you don't forget to close the app after finishing your ride.

• Power consumption: < 10%/h. Depends on the watch model and ambient temperature.

• Disabling Bixby wake-up command may further improve battery life.
