A free trial is a promise. "Try it, and if it's not for you, you can leave." How a product keeps that promise has a big effect on whether people trust it enough to stay.
For a subscription streaming service, the trial is also the most important stretch of the customer relationship. At Travelxp, a lot of our thinking about subscription health came back to what happened in the first days after someone signed up. If the trial didn't show people something worth paying for, no amount of reminder emails would fix it.
Trial length
There's no universal right length. The question is how long a typical person needs to experience the value.
For a streaming service, that might be enough time to watch something they care about and come back at least once. For a productivity tool, it might be enough time to use it on a real task. Shorter trials create urgency. Longer ones give more chance to form a habit but also more time to forget.
I'd look at when people who eventually convert usually have their key experience. If most of them have it in the first few days, a long trial may not add much.
Card upfront or not
| Approach | Pros | Cons |
|---|---|---|
| Card required | Higher trial to paid conversion, filters casual sign-ups | Fewer people start the trial |
| No card required | More people start, lower barrier | Lower conversion, needs a strong upgrade moment |
Neither is right in every case. Card-required trials tend to convert a higher share of trial users, but you start with fewer of them. It's worth testing in your own market rather than assuming.
If you require a card, be very clear about when the first charge happens. Surprise charges create refunds, chargebacks and a lot of angry reviews.
Design the first session
The trial is wasted if people sign up and don't find anything. For streaming, that means:
- Getting them to something relevant quickly, ideally based on what they chose at sign-up.
- Making sure the first play actually works on their device. A failed first play during a trial is very hard to recover from.
- Showing what else is available so they have a reason to come back.
I'd track how many trial users start a play in their first session and in their first few days, broken down by platform. That's one of the strongest early signals of conversion. The basics of measuring this are in the streaming metrics post.
Reminders should be honest
Send a reminder before the trial ends, telling people when they'll be charged and how much. Some platforms require this. Even when they don't, it's the right thing to do.
It might feel like you'll lose some conversions. You might. But people who forgot to cancel and get charged are more likely to ask for refunds, complain or never come back.
Apple and Google both have specific rules about how free trials and introductory offers work for subscriptions in their stores. 1 2 Check them before designing the flow for mobile or TV.
Make cancelling easy
If cancelling is hard to find or takes several steps, people get frustrated and you get bad reviews. In some markets, there are also legal requirements around how easy cancellation must be.
You can ask why they're leaving and offer an alternative, like a cheaper plan or a pause. Keep it short and respect the answer.
Look at what happens after conversion
A trial that converts well but leads to high cancellation in the first paid month isn't working. Track retention for trial cohorts after their first charge. That tells you whether people converted because they valued the service or because they forgot.
The trial is part of the product. It deserves the same care as any feature, because it's the first real impression most subscribers get. If you're still choosing a business model, I covered the options in OTT monetization models.
