Free trials people actually start
Make trials feel clear, easy to redeem, and low-risk — lessons from Blinkist, Slopes, Going, and more.
Explained like for kids
A free trial is like a sample at the ice cream shop. If the sample is confusing, feels like a trap, or needs a long form first, kids walk away. Show the steps, make starting one tap, and say “trial” out loud.
Examples
Each example has a kid-friendly “why,” then a clear Don't and Do with a real UI mock so you can see the difference.
Show how the trial works
Like for kids: Before you borrow a library book, the librarian says when it’s due. Trials need the same calendar story.
Don’t
“Start free trial” with no timeline
Fear of surprise charges. More complaints, fewer starts. Blinkist’s unclear trial drove support pain.
Blinkist Premium
Start free trialWhen do I get charged?
Do
Day-by-day: start → reminder → charge
Blinkist’s clear 7-day breakdown: +23% trial signups and far fewer complaints.
How your free trial works
- Today — Full access starts
- Day 5 — Reminder notification
- Day 7 — Trial ends, plan begins
Payramp, not paywall
Like for kids: A ramp helps you ride up. A wall stops you. Starting a trial should feel like a ramp.
Don’t
Secondary screen of plans before the trial
Extra steps kill momentum. People abandon before tasting value.
Decide before you can try
Do
One-tap “Redeem your free 2 weeks”
Slopes’ payramp: +25% trial starts. Feels like gaining, not paying.

Say “trial” in the CTA
Like for kids: “Sign up” sounds like homework. “Trial for free” sounds like a sample — temporary and safe.
Don’t
Vague “Sign up for free”
Doesn’t highlight the premium trial value. Going saw weak conversion.

“Trial for free” (or similar)
Going’s three-word change: +104% trial starts month-over-month.

Trial for freeRemind before charging
Like for kids: A friend who takes your toy without asking loses trust. Remind people before Day 7.
Don’t
Silent conversion to paid
Chargebacks, anger, churn. Feels like a trap.
Your trial ended. You’ve been charged $69.99.
Surprise = complaints
Do
In-app / email reminder before billing
Shaw Academy’s free trial reminder: +14% sales — and keeps trust.
Trial ends in 2 days
Cancel anytime, or keep Premium.
Remember these
- Explain the trial timeline (start → reminder → charge).
- Use a payramp: one-tap “redeem free trial,” not a wall of plans.
- CTA copy matters: “Trial for free” beats vague “Sign up.”
- Remind people before the trial ends — don’t surprise-charge.
