Mobile app user acquisition costs range from $1-15 depending on vertical, with gaming at the low end ($1-4) and fintech at the high end ($5-15). iOS users cost 20-40% more to acquire than Android, driven by attribution complexity and audience targeting limitations post-iOS 14.5.

What Drives CPI Variance Within Verticals (Gaming Example)
| Factor | Impact on CPI | Example Scenario | Cost Difference |
|---|---|---|---|
| User LTV Target | Highest | Casual vs. hardcore games | +/- 50% |
| Retention Day 1 | Very High | 30% vs. 60% D1 retention | +/- 35% |
| Install Source Quality | Very High | Organic vs. paid heavy | +/- 40% |
| Creative Performance | High | Top 10% vs. bottom 50% creatives | +/- 30% |
| Audience Saturation | High | Tier 1 vs. Tier 3 countries | +/- 45% |
| Seasonality Phase | Medium | Pre-launch vs. mature game | +/- 25% |
| Ad Network Competition | Medium | Solo campaign vs. crowded vertical | +/- 15% |
Analysis
CPI benchmarks tell a clear story: verticals with lower user monetization (gaming) compete on volume and efficiency, while high-ARPU verticals (fintech) can sustain 4-5x higher acquisition costs because their unit economics support it. The iOS premium is structural, not temporary. After iOS 14.5, brands lost deterministic conversion tracking on iOS, forcing reliance on aggregated data and longer attribution windows. This uncertainty pushes up cost because advertisers bid more conservatively and platforms have less targeting precision. Android offers the inverse: better attribution, larger international scale at lower costs, but with quality variation. Within any vertical, the real variance comes from creative performance and retention targeting. We've seen campaigns at RocketShip HQ achieve $1.20 CPIs in saturated gaming categories through superior creative iteration and audience sequencing, while adjacent campaigns in the same vertical hit $4+ through static creative and broad targeting. The outliers (subscription hitting $8 vs. gaming at $2) reflect fundamentally different business models. Subscription apps need users with demonstrated preference for recurring payments, which requires higher-intent audiences.
What This Means For You
First, know your vertical's baseline and use it as a sanity check, not a target. A fintech app benchmarking against gaming CPIs will over-optimize and miss growth. Second, iOS requires a 12-week learning window minimum due to aggregated conversion modeling. Don't pause iOS campaigns after week 2 thinking they're broken. Third, prioritize D1 retention measurement over CPI obsession. An app with 60% D1 retention can support 3x higher CPI than one at 30%, making retention optimization the highest-ROI lever. Fourth, if your CPI is 2x the benchmark, the problem is usually creative staleness or audience scope. At RocketShip HQ, we see brands cut CPIs 25-40% just by rotating creatives every 2 weeks and testing audience expansion. Finally, geo-arbitrage is real: shifting budget to Tier 2-3 countries can cut CPI 50-70%, but only if your product monetizes those users at similar ARPU. The math matters more than the headline cost.
