Stress-test true developer margins under commissions, Apple Search Ads defense, and regulatory CTF fees.
Defensive bidding on own brand & category keywords
Eligible for year 2+ 15% rate if standard program
Triggers €0.50 Core Technology Fee (CTF) over 1M threshold
Apple’s standard 30% commission is increasingly only the baseline platform take. When publishers defend their branded search placements on the iOS App Store, Apple Search Ads (ASA) cannibalizes an additional 12% to 25% of gross revenues. In the European Union, while alternative storefront terms lower nominal store commission to 10% or 17%, the Core Technology Fee (€0.50 per annual install over 1M) imposes severe marginal drag on freemium architectures. This simulator models the real bottom-line developer margin after platform capture.
