What you get
- Record the intro price, the price it becomes and the date it changes on any subscription — a new one, or one you already track.
- Enter it the way the offer was worded: a percent off, an exact price, or a one-time "Pay once" total.
- Set how long it runs as a number of payments, from 1 to 24, or as a date you pick yourself.
- A reminder goes out seven days before the change by default, with its own switch and a lead time you can set anywhere from 1 to 30 days.
- The regular price comes back by itself: the next time you open Suby on or after that date, the switch has already happened.
In detail
The date and both prices stay on the subscription
Open a subscription running an intro price and its details screen shows a ticket: what you pay now, the regular price struck through beside it, and the line "Until Mar 12, 2027 · then $17.99". The stub under the tear carries the savings still to come, or "Changes on Mar 12, 2027" once there are none, and inside the last seven days it reads "Promo ends in 5 days" instead. Back on your list, a Promo filter narrows it to the ones still running below their regular price, and each of those rows carries a perforated edge down its side.
The savings figure counts only the charges still to come
Streaming prices rose about 25% between March 2024 and March 2026. An intro price ending moves your own bill the same way, except that the size of the step and the date it lands were both settled the day you signed up: $4.99 becoming $17.99 is $13.00 a month, or $156.00 more across a year. The figure Suby shows is what is still ahead of you rather than what the deal was worth in total — with six discounted payments left, the ticket reads "You save" $78.00 beside "6 payments left on promo", and after two of them it reads $52.00.
Every charge is priced on its own date
Suby prices each charge on its own date instead of multiplying today's price out. Take $4.99 a month for six months, then $17.99. The next twelve months are six charges at $4.99 and six at $17.99, so the subscription's yearly figure reads $137.88 — not the $59.88 you get by assuming the intro price holds, and not the $215.88 you get by ignoring it. The same arithmetic runs the calendar, cycle cash flow, the renewal runway and the upcoming charges on the home-screen widget.
The reminder is already on, seven days ahead
"Promo ending" is switched on out of the box and set to seven days. The notification is headed "Price change coming", and the line under it names the subscription, then "goes to $17.99 on Mar 12, 2027". It has its own switch in Settings, Notifications, and its own stepper for the lead time, anywhere from 1 to 30 days, so seven is only where it starts. Suby holds each subscription to one banner a day, so a promo warning that shares a day with a billing reminder arrives as one message rather than two.
The regular price comes back without an edit from you
The switch runs whenever Suby runs — on Android a background job can do it before you open anything, and otherwise the next time you open the app on or after the date, that evening or two weeks later, the subscription is already on its regular price with the promo fields cleared. The change is written into the subscription's price history as "Promo ended", stamped with the date it took effect rather than the day the app caught up, so a six-month spending trend steps in the right month even when the rollover ran late.
How it works
-
Turn on the promo price
Add a subscription, or open one you already track and tap edit. Put the regular price in the Price field at the top — that is what you pay once the intro ends. Then scroll to Promo and turn on the row reading "The price you pay now changes on a date".
-
Enter it the way the offer was worded
A sheet opens with three modes side by side: % off, Exact and One-time. Only % off derives anything — it works the intro price out from the regular price you already entered. Exact takes the figure you were quoted, and One-time takes a "Pay once" total for a deal paid up front, which the ticket then compares as totals rather than per charge: $59.99 covering twelve months of a $9.99 plan shows "covers 12 months" and "vs. $119.88 regular". If what you enter matches the regular price, the sheet says so — "Matches the regular price — nothing changes".
-
Say how long it runs
"Lasts for" counts payments, from 1 to 24, and Suby works the date out from your billing cycle. "End on a date" lets you pick the date instead. If the date has already passed, or falls before the next payment so the discount is never charged, Suby says so before you save.
-
Read the line back, then save
Close the sheet and the Promo row reads back what you entered: "You pay $4.99 now. On Mar 12, 2027 it becomes $17.99." Save, and nothing further is needed — the reminder is scheduled and the date sits on the subscription from then on.
Questions
When does my intro price end?
On the date recorded on the subscription. Open it and the ticket reads "Until Mar 12, 2027 · then $17.99", with "Changes on Mar 12, 2027" or the payments still to run underneath. Suby does not find that date for you. You enter it when you set the price, either as a number of payments or as the date itself. Once it is in, that is the date every screen works from. It is the first day you are charged the regular price, so the discount covers every charge up to it.
How do I find out when my discount ends?
It is usually in the confirmation email from when you signed up, on the plan or billing page inside your account with the service, or on that subscription's entry in your App Store or Google Play settings, which shows the next charge date and its amount. Suby is not connected to the company charging you and cannot look it up. You only have to find it once.
Is a free trial the same as an intro price?
No, and Suby records them separately. If your price goes up after a free trial, that is the trial: turn on Free trial on the form and set its end date there, and it keeps its own reminder switch in notification settings. An intro price is a stretch at a lower paid price, which is the promo section described on this page. A subscription can carry both, and each keeps its own end date and its own reminder.
Does Suby detect when a company raises its price?
No. Suby does not watch any company's pricing and cannot detect a change made on their end. The intro price, the price it becomes and the date all come from you, typed in from the offer you accepted. What Suby does with them is store them, do the arithmetic, warn you before the date, and put the regular price back afterwards. It only ever updates your own record: it never contacts the company on your behalf, and it never cancels anything.
Can I set an intro price while importing from a screenshot?
No. Snap Import reads what your store screenshot actually shows — the service name, price, currency and billing period — and a screenshot has no way of saying what that price turns into later, so there is no intro-price field on the review screen. Import first, then open the subscription, tap edit, and add the promo price, the date and the price it becomes.
Is any of this Premium?
No. All three input modes, both ways of setting the duration, the savings figure, the reminder, the Promo filter and the switch back on the day are in the free app, with no cap on how many subscriptions carry an intro price. Premium covers separate things — encrypted cloud backup, widget settings, the currency map and live rate refresh, longer chart ranges in the converter, and lifting the cap on custom services — at $1.99 a month or $14.99 a year, with a 7-day free trial.
