About SilentLog for Apple Watch

Since Apple Watch has no GPS attached for now, SilentLog for Apple Watch doesn’t work correctly without connecting to your iPhone.
In case a future Apple Watch will be able to locate the current location on its own, we will make the best of the feature.


Notification (says “Keep running in the background”) comes when the app terminated

As of v2.1.0, SilentLog show you a message when you terminate the app from the multitasking view.
Terminating the app loses the logging quality.


“Walk” is counted as “Transport” or in reverse

Whether “Walk” or “Transport” is determined by the motion sensor chip instrumented on the device (iPhone 5S, 6, 6Plus).
We will improve this determination based on your context of activity.


Strange place or time is logged

In case your device hard to get GPS data, your location and activity cannot be logged correctly.
To enhance logging quality, try keeping the Wi-Fi switch on, even if you have no access to the Internet. iPhone is able to know where you are by Wi-Fi spots around you.
We continue improving logging quality in any situation as possible.


Worry about device’s battery life

You can turn on “Battery Saving Mode” from “General” on the menu.
Battery Saving Mode reduces battery consumption instead of logging location accuracy compared to the normal mode.



Thank you for using SilentLog and please let me know if you have any other questions.
