How FaithFull grows
25 tactics and 41 figures from 1 interview.
faithfull.aiFaithFull is a calorie tracker for Christians trying to lose weight, spun out of the most-used feature of the founder's older workout app. It grew through Meta ads tested on Android before moving to iPhone, sold through a long onboarding built from a phone sales script and a paywall with no free trial. Most of its gains came from split tests on onboarding screens, prices and paywall labels.
- FaithFull rebuilt its onboarding from a phone sales script, asking about pain, goals and life after reaching them, and reported install-to-paid rising from 3.28% to 5.11% in a month as onboarding grew from about 10 to 26 screens.FaithFull (1)FaithFull (2)
- With no free trial, FaithFull added a monthly live group coaching call and announced it on one onboarding screen; revenue per payer rose from $39 to $43 and purchase conversion from 7% to 9.78%, prices unchanged.FaithFull (1)FaithFull (2)
- Raising monthly to $19.99 and quarterly to $39.99 while keeping annual at $59.99 lifted revenue per payer from $32 to $38, and the pricier paywall converted better; dropping a label on the quarterly plan also pushed buyers to annual.FaithFull (1)FaithFull (2)FaithFull (3)
- FaithFull sent Meta sign-up, paywall view and buy-tap events alongside purchases and reported cost per result dropping about 50%.FaithFull
- Ads were tested on Android first and only lasting winners moved to iPhone; after about 8 months the iPhone campaign reached about 90% day-one return on ad spend, a figure the founder tied to several changes at once.FaithFull (1)FaithFull (2)FaithFull (3)
- A real creator reshooting the best AI-made ad with the same script beat the original on Android and iPhone, while App Store search ads did less well than Meta and were put aside.FaithFull (1)FaithFull (2)
