Designing a 30-day trial that earns the conversion

The convention in gym software is a 14-day free trial that asks for a credit card upfront. It works because most people forget to cancel. We don't run that trial. We don't ask for a card, and we give thirty days, not fourteen. Here's the reasoning, and the exact sequence we use to turn the longer window into a higher conversion rate.

Why thirty days, not fourteen

Fourteen days is the wrong window for software a gym owner will use to run their business. Two weeks isn't enough time to:

• Onboard your members (the QR poster cycle alone takes ten days).
• See the first cohort of members log a full week of workouts.
• Run payroll once and confirm the numbers reconcile.
• Hit a renewal date and watch the auto-billing flow work.

A 14-day trial forces the owner to make the buying decision before they have evidence. They either say no out of caution or say yes out of sunk-cost -- neither of which is a healthy customer relationship.

Thirty days lets the owner do all four things above. By day 30, they either have evidence the software works or they have evidence it doesn't. We win more decisions when the decision is grounded in evidence instead of vibes.

Why no card

Asking for a card upfront does two things: it filters out tire-kickers and it makes the trial feel like a commitment. Both of those sound like benefits to the company running the trial. They are not benefits to us.

The tire-kickers we'd filter out are the same gym owners who are cautious because they've been burned by software contracts before. Those are exactly the customers we want, because the moment they trust us they become evangelists. Asking for a card on day one tells them we expect this to go badly. We don't.

We also don't want a 31st-day surprise charge. If you forgot the trial was running, you should not be billed. We will email you on day 30 and ask. If you want to keep going, you click a button and add a card. If you don't, the workspace freezes politely and your data sits there for ninety days in case you change your mind.

The four touchpoints that earn the conversion

Most trials silently expire. Ours actively converts, by giving the owner a reason to look at the product on the days that matter.

Day 21 -- "your members are using it"

This is the first scheduled email we send during the trial. It's a short, plain summary: how many of your members installed the app, how many workouts they logged this week, the most-popular movement (always a specific exercise -- "back squat, 3,420 logged reps"). The point is to make the owner go look at the dashboard and see real activity, not a polished demo.

If the numbers are bad, the email tells them why and links to the QR poster section. If the numbers are good, the email gets out of the way.

Day 25 -- the founder check-in

I send this one personally. It's two sentences. "How is week three going? Anything I can fix this week?" I get replies on about half of them, and most of the replies are small ergonomic complaints -- buttons in the wrong place, a missing field, a copy mistake. I fix as many of those as I can in the next 48 hours and reply to say what changed.

This is the highest-leverage touchpoint we have. Owners who get a real human reply, with a real product fix, convert at roughly 2.4x the rate of owners who don't.

Day 28 -- "what happens on day 30"

Two days before the end, a clear note: trial ends Saturday, here are your options. The options are stated plainly. Option A: do nothing, the workspace freezes, your data is preserved for 90 days. Option B: add a card, billing starts Saturday. Option C: extend two weeks if you need more time -- reply with one word and we'll extend it.

The mention of Option C is unusual. It exists because the only people who use it are owners who genuinely need more time, and the owners who take the extension convert at almost the same rate as owners who convert at day 30. The cost of extending is two weeks of compute. The upside is a customer who feels respected.

Day 30 -- the gentle gate

If they haven't acted by 9am on day 30, the app shows a small banner: "Your trial ends tonight. Add a card to keep going, or reply to extend." The banner doesn't block anything. The owner finishes their morning classes, sees the banner ten times, and decides.

We win the trial here, not on day 1.
