Clean UI and strong concept for tracking subscriptions across projects. API support is a big plus. as tell claude to add new subs for me. One useful workaround for API users: create a full block of temporary entries with single tags to map tag IDs and build a reference table. Some UX improvements like autocomplete and search in tags/categories lists would make it even stronger. Developer is responsive via email and actively improving. Promising tool with solid potential. API needs extending to support for adding Reminders, Notes and Payment method (these are UX only) but overcame this with adding a custom tag for each payment method x9999 for which cc it belongs to and tag for autorenew, vs annual-review for ones want to check on before expiry.
