Credits, not trials: let the value land first

Our 14-day, card-upfront trial ran out right when users were getting ready for premium. I replaced it with monthly credits people spend at their own pace. Free-to-paid conversion went from ~4% to ~7%.

At a glance

01 Problem

A 14-day premium trial at signup, card required. People balked at the card, and the trial ran out before they were ready for premium.

02 Insight

Most users need one to two weeks to get comfortable with the device, the app and a routine. We were optimising for trial activation, not for discovering value.

03 Solution

Monthly credits every user can spend on AI Coach, Sportstech Move and other premium features whenever they're ready. Upgrade prompts come after use. No hard paywall.

04 Result

Free-to-paid conversion went from ~4% to ~7% (+75%), measured within 60 days of signup.

You're in the 30-second version. The full story covers the research, why the window is 60 days, and the risks I designed around.
01 Context

Premium was sold against a deadline.

Sportstech sells smart treadmills, walking pads and strength equipment. The app has a free tier. Premium unlocks the features we'd spent the year building: AI Coach, Sportstech Move and other advanced experiences.

The way into premium was the standard playbook. At signup, every user got a 14-day premium trial, and they had to add a credit card first.

Free-to-paid conversion and subscription revenue were my KRAs. Conversion was sitting at around 4%.

02 Problem

The trial ran out before the user was ready for it.

A card wall on day one

People who had only just started with the product didn't want to hand over card details for features they hadn't tried yet. Many never started the trial.

The clock started too early

Most users took one to two weeks to get comfortable with the device, learn the app and build a basic routine. By the time they wanted advanced features, most of the trial was gone.

03 Insight

We were selling the trial. We should have been selling the value.

Talking to users changed the question. The objection wasn't to premium itself. It was to being asked to commit before they knew what it did for them, on a timeline that ignored how long it takes to settle in with a new machine.

A trial starts the clock when the company is ready. I wanted the ask to arrive when the user was.

“We were optimising for trial activation rather than helping users discover the value of premium features.”
— My read after the user conversations
04 Solution

Give every user a wallet, not a deadline.

Instead of a trial, every user gets a fixed number of credits each month to spend on premium features: AI Coach, Sportstech Move and other advanced experiences. They try whatever they want, whenever they're ready.

I worked with design and growth on the upgrade prompts, so the ask comes after someone has used premium, not before. There's no hard paywall.

60 days covers the settling-in weeks plus a full month of credits. That's long enough to see whether using premium turns into paying for it.

Design decisions
  1. One currency, every premium feature. Credits work across AI Coach, Sportstech Move and advanced workouts, so people find the feature they would pay for.
  2. The prompt follows usage. The upgrade ask shows up once credits are spent, when the value is fresh. It never shows up at signup.
  3. "Not now" always works. There's no hard paywall. When credits run out, the free app keeps working and the wallet refills next month.

A 14-day window would have measured the problem itself.

Why 60 days, not 14The whole insight was that users need one to two weeks just to get comfortable with the device before they're ready to explore premium. Measuring at 14 days, the old trial's window, would have measured the exact problem we were trying to fix.

07 Guardrails

Free credits could have replaced premium. The metric was built to catch that.

Built into the metric

Giving premium away

The risk: credits satisfy people, so they never pay. That's why success meant paid conversion, not credit usage. If credits had cannibalised premium, the headline number would have stayed flat. It rose.

Built into the window

Grading on a moving clock

The 60 days run from each user's own signup date, inside signup-month cohorts. Every cohort, before and after launch, gets the same amount of time to convert.

Built into the design

Asking too early, again

Moving the ask to day 30 would just repeat the trial's mistake. So the upgrade prompts, built with design and growth, follow usage, not the calendar.

08 What I learned

Pricing is a timing problem before it's a price problem. Ask for money when people can feel what they're paying for.
