Hi Product Hunt! I am Pierantonio, an independent software architect and the maker of Subby. I built Subby because annual, quarterly, and weekly subscriptions make it surprisingly difficult to understand what recurring services really cost each month. Subby converts every billing cycle into a comparable monthly share while keeping the actual renewal dates visible. The app is intentionally focused: no bank connection, no account, no advertising, and no tracking. Your archive stays on your iPhone, with reminders, Home and Lock Screen widgets, a 12-month renewal forecast, local profiles, and an XML backup you can move between devices. Subby is free and available in English and Italian. I would especially value feedback on the onboarding, the clarity of the monthly overview, and which recurring costs you find hardest to track. Thank you for trying it.
