A paid app's trial runs on its own clock, separate from your plan trial, and the two dates usually differ. What happens at the end depends on one thing: whether a card was added.
Two different endings
No card added. This is what the ordinary Install does. No subscription exists at all, so when the fourteen days are up there is nothing to charge and nothing is charged. The app locks instead. Your records stay exactly where they are, and one button turns it back on. See what happens when an app trial ends.
A card added. Choosing Add card and subscribe sets up the subscription immediately, with the rest of your trial carried across to it. Nothing is charged during the trial. When it ends the subscription starts charging on the cadence you picked, and the app keeps running with no interruption.
Both paths are explained in start an app trial without a card.
Where to see the dates
Settings, then Billing & Plan. The monthly breakdown lists your plan and every installed paid app as its own line. During a trial each line shows how long is left and what it will cost afterwards, so the first charge is never a surprise. See what your apps are costing you.
The trial only ever runs once
Removing an app and adding it back does not restart the trial. The original end date is kept and reused.
We say this plainly because the alternative is a business that thinks it has another fortnight and gets billed the same week. If you have already trialled an app, the install is refused and you are pointed at subscribing instead.
If you decide against it
With no card added, you can simply let it lapse. Nothing is charged either way.
If a card is on file, remove the app before the trial ends and the subscription is cancelled outright, so it can never convert. See remove an app, and your data.
Cancelling your plan now ends your app subscriptions too
This changed in 2026. Your plan and your apps used to be separate subscriptions that had to be cancelled one at a time. They are not any more.
When you cancel your OneBookPlus plan you are shown a list first, headed "Cancelling your plan also ends these app subscriptions", naming every app subscription with its amount and when it ends:
- an app still on a free trial is cancelled immediately and is never charged. It also comes out of your sidebar there and then, because there is nothing paid for to run out
- an app already being paid for stops renewing, and you keep access to the end of the period you have paid for
You then choose Keep my subscriptions or Cancel plan and apps. Nothing happens until you choose. The same cascade applies if you cancel from the Stripe billing portal instead of from OneBookPlus.
Resuming
Resume your plan before the cancellations take effect and the app subscriptions that were only scheduled to cancel come back with it. The ones cancelled outright do not, which in practice means any app that was still on a free trial when you cancelled. Those have to be subscribed to again from the App Marketplace.
The Resume button does not list what came back, so check the monthly breakdown on Settings, then Billing & Plan afterwards. An app that is missing from it is one of the outright cancellations. See what your apps are costing you.
Who can do what
Adding, removing and subscribing to an app: an owner or an admin. Cancelling or resuming the OneBookPlus plan itself: the owner only.
