The renewal date
On your last bill or your welcome email. Without it there is nothing to count down to.
How it works
Add what you pay for, get told before the deadline that matters, and have the right number to hand when you act. Everything else the app does is in service of those three.
Pick a category, pick your provider from the Irish directory, and enter the renewal or contract end date. If you know the notice period, enter that too — it is the number that decides your real deadline.
Amounts are optional. If you add them, bills on different cycles are normalised to a monthly figure so the totals are comparable. Account numbers and notes are optional too, and they never leave the phone.

Your phone schedules the reminders itself. They arrive whether or not you have signal, and they work without an account because nothing has to be looked up on a server.
Each bill gets up to four, and every one of them moves when you change the notice period. Reminders are never scheduled into the past, so a bill added the week it renews simply gets fewer of them.

Each bill links to its provider's customer service line, emergency number, email and switching page. The directory is downloaded to your phone, so it works offline.
Details are checked by hand, and the app tells you when an entry has not been confirmed recently rather than pretending otherwise. If you find a wrong number, there is a report button — that is how it gets fixed for everyone.

Worth having to hand
None of it is required — you can add a bill with a name alone and fill the rest in later. But these three turn a list into something that warns you.

Usually 30 days in Ireland, 31 at Sky. It is the difference between a reminder that helps and one that arrives too late.
Enough for the spending breakdown to be worth reading. Round numbers are fine.
Where we stop
A tool that also sells you something is not really telling you when to switch. So this one does not sell you anything.
