Subby remembers every subscription and bill you have, and reminds you before they charge you. No bank login. No account. Nothing to connect. You add each subscription yourself, in about twenty seconds, and it stays on your iPhone. A subscription manager, a bill organizer and a renewal reminder in one app. WHAT SUBBY DOES • Track every subscription and recurring bill: streaming, music, gym, insurance, cloud storage, software, anything that renews. • Get a reminder before every renewal, on your schedule: same day, a few days ahead, a week ahead, or a custom lead time. • Mark a payment as paid straight from the notification. • See one clear total for the month and for the year. • Keep a full payment log with monthly totals, filtered down to any single subscription. • Sort into categories and payment methods, pause what you are not using, archive what you cancel. REMINDERS THAT LAND One heads-up per charge and nothing else. If a payment goes unpaid, Subby keeps reminding you for up to a week, so a forgotten free trial does not quietly become a yearly charge. Cancel in time, or decide to keep it. Either way, you knew it was coming. INSIGHTS Due, paid and total, by month or by year, broken down by category or payment method, with a six-month trend. Your real monthly spending, on one screen, instead of a number you are guessing at. HOME SCREEN WIDGET (PRO) Your next payments and their countdowns, one glance from the Home Screen, with one-tap mark as paid. BUILT FOR REAL BILLING Weekly, every two weeks, every four weeks, monthly, every two months, quarterly, half-yearly, yearly, or a custom cycle up to every three years. 46 currencies with up-to-date exchange rates, so a subscription billed in another currency still lands in your main total. 600+ BRANDS READY TO GO Logos and brand colors are built in, so adding a service takes a couple of taps. Missing one? PRO members can request it and we add it for everyone. ADD FROM A SCREENSHOT (PRO) Snap a confirmation email, a bill or a store page, and Subby fills in the service, price and billing cycle for you. You review it before anything is saved. CLOUD BACKUP (PRO) Automatic backups to iCloud, or to your own Google Drive, so your list survives a lost or replaced iPhone. You can also back up to this device and restore from a file. IN YOUR LANGUAGE 31 languages, right to left layout included. Pick the app's language inside Subby, whatever your iPhone is set to. PRO IS ONE PAYMENT Subby is free, with ads. PRO is a single one-time purchase, not a subscription. It removes the ads and unlocks the widget, cloud backup, screenshot import and icon requests. The free app tracks everything, with no cap on how many subscriptions you add. The unlock stays with the Apple Account that bought it, and Restore Purchases brings it back on your other Apple devices. PRIVACY No account, no sign-in, no bank connection. Subby knows what you tell it, nothing more. Your subscription list lives on your device, and backups go only to storage you already own.

The clearest difference is in-app purchases: Subsum at none against Subby Subscription Tracker's 1. Subsum also leads on ads (none vs shown) and iOS requirement (16.4 vs 18.6). On price and device support there is nothing between them.
