Subscriptions
Allows you to track your subscriptions and categorise them. Lifetime license.
Analytics
What I like about it
Different ways to display your subscriptions (list, grid, table), clear month-to-month analytics, categorisation and tags, all offered under a lifetime license for all devices.
What I don't like about it
Only compatible with Apple devices. The UI is sometimes buggy and could be snappier, though the developer is responsive on Reddit and as far as I understand, will release version 3 around February 2025.
