I've been tracking every one of my flights, and battery charges for my two batteries using a flight log website.  They also have an app.  Google "Drone logbook".  Website is drone.cloud2  something or other.  I was surprised to see I've logged over 2 hours of flight time this year already, despite the harsh winter.  Really good for tracking how many times you've charged your batteries, etc.

Using the website is free.  The app is a paid download which I have not tried yet.
