From the developer:
Dues makes it easy to manage all your subscriptions and get reminders before you are billed or before the trial expires. It works for any subscription type, the online ones (Netflix, Spotify, you name it), but also for offline subscriptions (magazines, insurances, taxes, phone services, and many more).
