I think I got the app with the one time purchase option rather than a subscription. How do I find out for sure?
Also, I am going to be on a 6 week ride this summer and I would like to put the app on my tablet so I can have a larger screen to view while in camp in the evenings. Do I have to purchase another app for the tablet?
There is no subscription yet.

The app is working fine on tablets as well.
Kurviger Pro is offered via an one-time purchase.
Google Play shows in all app descriptions if they are free or paid, contain ads, in-app purchases / subscriptions, etc.
No, see more details in documentation and Google Play Help:
“You can use apps you bought on Google Play on any Android device without paying again. However, each device must have the same Google Account on it.”
