Reminders · free for everyone
The bill reminder app that tells you before the charge lands.
Subby is a bill reminder app that never sees your bank. You add a subscription or a bill yourself, once. After that it warns you before every charge, from the same day to a week ahead, or any custom lead time you set.

Live demo. In the app, you mark it paid with one tap from the notification.
Renewal reminders on your schedule, not ours.
Every subscription gets its own lead time. Give the yearly renewal a week of notice and leave the monthly bill on the day it charges. The reminder itself arrives in your own language, one of 31.
Rebuilt for 2.0
Subscription reminders you can lean on.
Missed reminders are the oldest complaint about apps like this one, and old versions of Subby earned their share of it. We rewrote the reminder engine in 2026 around one rule. A reminder that doesn’t arrive is worse than no app at all.
Keeps nudging when unpaid
Leave a payment unmarked and Subby keeps reminding you for up to a week. It doesn’t fire once and vanish.
Survives reboots & updates
Subby re-checks your reminders every time you open the app, once a day in the background, and after any restart, update or time change.
Groups instead of spamming
Three or more due at once? You get one summary rather than one notification per subscription (on Android; iOS groups notifications by thread).
Planned ahead on iPhone
Subby pre-schedules iOS reminders 35 days out, so they arrive even if you don’t open the app for weeks.
“Great app. The feature to mark a subscription as paid from the notification is absolutely perfect.”
