Hi OkGoDoIt,
free tier contains 5 tokens.
I'm sorry you feel this way. Subscription model is a way to continue funding the developments and maintenance of the app.
I've seen so many one-time payments app turn into subscriptions (e.g. 1Password etc) or be abandoned by the developers.
$12/year or $1/month seemed a reasonable price for the service offered and what will come next, but I understand your point of view.
I just want to keep the service level as high as possible.
Sad to see this as a subscription, seems easy to justify paying $5 one time but not $12 every year.
