1. Project Overview

iSharing is a subscription-based location sharing app for friends and family's safety. The paywall is where all revenue is won — or lost.

After analyzing Mixpanel's existing data, we found that less than 1% of users subscribed during the onboarding paywall. Every A/B test required a full developer cycle. Testing was a luxury we couldn't afford.

2. Problem Statement

How do we build a system that can learn, test, and improve without relying on a developer for every change?

3. Research

  1. Competitive Research
    1. compare to competitors, our design is lack of nudge to build social trust

    2. Too much congtive load in one page

  2. Analyze current data (Mixpanel)
    1. Currently, 99% of the users do not subscribe during the onboarding

      1. within those 99%, 16-23% of users subscribe within 24 hours

    2. 75% users even click the CTA button, and abandon the transaction

4. Ideation & Strategy

<Not a random tests, a deliberate system>
  1. I proposed Superwall, a no-code paywall experimentation platform- and designed a 5 phase roadmaps.

5. Design & Iteration_1.

Multi page paywalls

Design your own trial

Instead of prescribing one paywall, we let users choose between 2 trial options.
1. Free 7 day OR

  1. $5.99 30-day.

The result

Users self-selected their best fit, converted more, and cancelled less

Clear Headline

6. Result

I ran 11+ experiements across 5 phases- from AA baseline testing to the flagship "Design your own trial".
The numbers prove the system worked. And the system kept learning

7. Takeaways

Reducing cognitive load and giving users a stronger sense of control proved most effective.
Short, multi-step paywalls performed better than long, scroll-heavy ones.
Allowing users to “design their own trial” — comparing plans or adjusting price options — increased engagement and trust, showing that autonomy drives higher conversion.
