Creates zigzag lines while not moving

Post by Optimistic » Fri Jan 27, 2017 5:41 pm

This is the best tracking app for android I have ever found. But so far I have found a few glitches. Most important of these is, it creates numerous zigzag lines when you are sitting idle. One morning when I woke up from night's sleep, I found that I traveled hundreds of miles east-west-south-north directions from my bedroom, though my phone was kept under my pillow for the whole night.

Second shortcoming is, it stops tracking in the second day if you do not clear the cache of the app.

The third one is, if the app is open when you are moving, then it creates straight line of your moving path. If back pressed and the app is left for background run, then it cannot create the straight line of the moving path. Instead, it creates some zigzag lines left to right (and deviates a few miles sometimes), though the moving direction remains right.

May the admin please let me know the causes of these issues?
Thank you in advance.

Hi,
Thank you for your feedback. When determining your location the tracker completely relies on the GPS chip in your phone. The tracker just forwards the coordinates received from your phone to the server.
So to reduce the zig zag please ensure that your phone has good GPS conditions. Usually conditions are good if the phone has clear view of the sky. When you are inside I recommend to switch off the tracker. As you have noticed the location would just jump around your home location and you are wasting battery. Alternatively you could configure a minimum distance in the app settings so the location at least is not sent to the server if the distance to the previously sent location is not big enough.

By the way, if you keep your phone under your pillow, please consider to switch off your phone or at least activate flight mode. As far as I know it is not good for your health to have mobile phone radiation permanently so close to the body.

If the app is in background it switches GPS off while it is not required to save battery. When GPS is activated again, it might need a few seconds until location is really exact. Maybe you could improve the quality if you open "Settings", "Expert settings", and set "Location fix send threshold" to "3" or "5". This will force the GPS to update the location 3 times (5 times) before the location is sent to the server.

Please note that the mentioned app settings influence how your track is presented to other users (or in the web portal map). But your track on your local app screen might still look the same.
