Build Better Paywalls with AI

Steve P. Young hosts Trent Hommeyer of Helium, an AI paywall builder and experimentation platform. Trent shows a Flappy Bird paywall (higher score = deeper discount, up to 50%) that won an experiment for a student AI app, argues for attention-grabbing animation, age-based segmentation, and 'who referred you?' authority cues for older users, and says app-to-web checkout via Apple Pay/Stripe now beats in-app purchase on trial-to-paid and retention. Ends with a live AI paywall build and two short app audits.

13 tactics

An AI study app · B2C · Helium customer

Beat the existing paywall in an A/B test on 10% of users; no numbers given

Built a Flappy Bird clone inside the paywall with Helium's AI chat (no hand coding). The higher the score, the deeper the discount, capped at 50%; at e.g. 30% the offer pops up and the user can keep playing for more. Shown to ~10% of users as an experiment. Best for whimsical, already-gamified apps with a young audience, not focused business apps.

Wins 'really aggressively' in Helium tests, per the guest; no numbers

The paywall opens with some content visibly missing (something eye-catching), then the trial information animates in from the side. Rationale: many users hit X without reading even a trial-explainer paywall like Blinkist's, so the first job is to get them to read one word.

With animations beat without in a Helium test; no numbers

Floating bubbles in the onboarding background, splash effects on taps, and haptic feedback so each step feels satisfying and people don't put the phone down.

A screen in onboarding saying the app is 'creating your experience' (an animated build-up step).

Converts better, confirmed by two competing apps; no numbers

For an audio app (e.g. sleep sounds or relaxing soundscapes), play the actual audio while the user goes through onboarding.

Works well with older audiences, per the guest; no numbers

In onboarding, add a 'Who referred you?' question whose options signal legitimacy, e.g. 'My personal trainer' or a television ad, even if the app has no trainer partnerships or TV ads. Older audiences respond to authority; whimsical/gamified paywalls work for younger users instead.

Identify the variables that drive conversion for your app (age is the big one; people above ~35 think differently) and run separate experiences and experiments per segment, so learnings from one group don't pollute the other. E.g. show a tailored paywall only to users over 45.

Usually 8 are a wash and 1 makes a difference

Use a remote paywall tool (no app update needed) to test many variants at once: three plans on one paywall, different default-selected plans, colour schemes, trial lengths (1, 3, 7 days). Customers run eight or nine experiments simultaneously.

Better trial-to-paid, retention and ARPU; first conversion slightly lower

When the user taps a plan, show the Apple Pay prompt directly (payment processed by Stripe) so it feels like a normal in-app purchase, rather than redirecting to Safari or opening a Stripe link. Enabled by the Epic rulings; avoids Apple's 15-30% cut. Helium has tested app-to-web variants for years.

App Masters · B2B · app marketing agency

Big drop-off every time; did worse than Apple in-app purchase

On plan tap, open a web checkout outside the app (Safari page, like Flo Period Tracker does) or pop up a Stripe payment link.

A subscription app · B2C · App Masters client

$1.4M of a client's $2M ARR came from iPad

Client app sold on iPad as well as iPhone; host recommends iPad to a kids' drawing app because few developers target it.

App Masters clients

Converts better as a fallback, clients say; anecdotal

Main onboarding paywall offers a 7-day free trial. If the user dismisses it or cancels the trial, follow up with a 14- or 30-day trial offer. Do not make the long trial the default.

Helium's 'Get Started' asks a few questions including average revenue. Small apps get in directly; big apps see what looks like a waitlist so the team can talk to them first. Guest says it may soon open to everyone instantly.
