This is a GREAT app. I have been using it for YEARS already on all my vehicles. Very user friendly and easy to use. With the stats  plots and logs  it shows you everything. The only thing keeping me from giving it a 5 star rating  is the fact that it does not auto backup to either Google drive or any cloud storage for that matter. This means that after putting fuel in my vehicles  I have to back it up every time. I did once all my vehicles data  due to not backing it up  and then my phone broke  and had no way to retrieve the data. If there is any way at all that it can be auto back-upped  that would make this app PERFECT in all respects. Even if I have to pay for the app then  it will be worth it.
