I would definitely use it and pay if it could replace the "Your timeline" functionality of Google Maps. I have been using it frequently and since many years: it helps tremendously when I need to refresh my memory and there just isn't anything reasonably that can replace it at this point.
Bonus points for an ability to import from Google or some CSV, at least.
I have the desire for the same functionality. I really enjoyed the timeline history that Google Maps provided for me, but I ultimately disabled it out of privacy concerns. If there is a way to get revenue with this project, this will certainly be one of the app's future features. :-)
