This app is great for keeping track of your route. It works both ofgline and online and doesnt seem to crash like some other apps when the cellphone enters a standby modr.
The program allows you to save tracks.
The program give you the possibility to control the accuracy of the travking (vs resources\battery conumption) in several way including the frequency of the location registration. (note that for walking and refined drivong tracking you'll need, from my short experience, the GPS). The sampling time seems to be the most influencial factor (and feature) here.

I highly recommend this.  I would just say that I didnt try an app related directly to google (the company who releases the app). Obviously some apps use google services.

I tried 4-5 other apps that seem relevant for track monitoring. One was Ok but with much less feature and this one is the only one that does its job rigbt and gives you high degree of control on the route registration.

Tips for future improvement:
for future improvement:
1. Synchronize maps with offline mapping services (preferably free ones, e.g MAPS.ME etc) Currently, AFAIK, you cant download or use maps map (Im not 100% sure on that. maybe there you can synch with goggle ofcline map services) unless you are online
2. think I encounterred once a GUI related issue after several usages related to recording a new trail but I can't recall exactly.
