Challenge

The app could buy installs cheaply and profitably in two markets, but each attempt to scale pushed the payback window past the point finance would approve.

02

Strategy

We modelled the maximum CPI each market could carry at the required payback, then worked backwards: store conversion first, creative second, bidding last.

03

Execution

ASO rebuild — store listing, screenshots, localised keyword sets — followed by staged UAC and Apple Search Ads expansion. Creative was produced per market rather than translated, with a testing block running continuously in the background.

04

Result

Reported as installs at target CPI, store conversion rate by market and payback window by monthly cohort.

05

Learnings

Roughly half of the improvement came from the store listing, not the ad account. Buying traffic into a weak listing is the most common way to overpay for installs.

INDEXED TO BASELINE / MONTHS
Volume against cost: acquisition volume climbs while cost per outcome falls, both indexed to the pre-engagement baseline.
