That's actually a fair point, regarding the implications of a one time fee.

Personally, I don't like subscription-based apps so didn't want to create yet another one.

And I built this around my personal needs so I plan to support it indefinitely.

Regarding long term improvements, there is a number of paying users that once I achieve, any new users are basically profit.

The service was built to be cheap to run and maintain so I could charge a one time fee.
