Case Study: ABI Games Studio achieves up to 40% lower eCPI and higher ROAS post‑IDFA with AppsFlyer

AppsFlyer helps ABI boost ROAS post-IDFA, cutting eCPI for Apple Search Ads campaigns by up to 40%

ABI Games Studio, an Onesoft Studio team based in Vietnam and one of Southeast Asia’s top 10 game companies, needed more reliable, timely performance data after iOS 14.5 to optimize ad spend for its Hyper-Casual and Casual titles like Galaxy Attack. ABI selected AppsFlyer and implemented AppsFlyer’s latest SDK (with Apple Search Ads AdServices API and SKAN support) to close attribution gaps and get a unified view of Apple Search Ads and other Self-Reporting Networks.

AppsFlyer integrated deterministic attribution plus SKAN-aggregated views into a single dashboard, allowing ABI to accurately measure ROAS and retention and optimize campaigns in a post‑IDFA world. As a result, ABI cut effective cost per install by about 20–40%, reduced eCPI volatility, saved time on optimization, and planned a 50% budget increase for Q2–Q3 2021 — outcomes driven by AppsFlyer’s solutions.
