According to Sensor Tower Store Intelligence estimates, global mobile users spent $71.3 billion on apps and games in 2018, a 22.7% increase from $58.1 billion in 2017. Apple's App Store generated $46.6 billion, 88% more than Google Play's $24.8 billion, though Google Play saw faster growth at 27.3% versus 20.4%. First-time app installs reached 105.3 billion, up 11.1% year-over-year, with Google Play accounting for 75.7 billion downloads (13% growth) and the App Store 29.6 billion (6.6% growth).
Mobile gaming generated $54.7 billion, representing 77% of total app revenue, down from 82% in 2017. Game downloads totaled 38.3 billion, with Google Play contributing 29.4 billion and the App Store 8.9 billion.
European finance app installs hit 960M in 2025 but grew only 0.4%. BNPL apps grew 40% while crypto fell 35%, signaling a shift to utility. Neobanks win acquisition; traditional banks win retention (1.5-2x Day 30 rates). Web-to-app drives 41.8% of conversions but most brands can't measure the handoff. Nearly 1 in 2 investment app installs in Western Europe is fraudulent, distorting CPI and ROAS. Winning brands prioritize engagement, fraud detection, and cross-platform measurement.
Short drama apps are reshaping mobile entertainment, surpassing 850M downloads in Q1 2026 (up 140% YoY) with IAP revenue reaching $750M. Growth is concentrated in Southeast Asia, Latin America, and India, where these apps outpace traditional OTT in user acquisition. Engagement is surging: daily time spent grew 85% to 25 minutes globally, nearing OTT levels in Southeast Asia. For ad ops, the shift toward ad monetization in addition to IAP opens new inventory opportunities. Key players like FreeReels, NetShort, and Melolo are scaling via localized content and paid acquisition, creating competitive ad markets.
Gen AI apps have become the primary growth engine of the non-gaming market, with revenue surging 232% YoY to $6.1 billion between Q2 2025 and Q1 2026. The US leads with 38% of global revenue, while Japan and Korea emerge as key growth markets. AI Assistants are increasingly concentrated, with ChatGPT dominating, but vertical segments like AI Companions, AI Agents, and AI Image & Video offer fragmented, high-growth opportunities. Lessons from Plaud highlight success through vertical focus, deep localization, and precision advertising. For ad ops, targeting vertical AI segments and localized user acquisition strategies present significant opportunities.
Marketing attribution is critical for connecting spend to revenue, but platform self-reporting and last-click bias distort budget decisions. Single-touch models (first/last-click) are simple but miss the full journey; multi-touch models (position-based, data-driven) are more accurate but require robust data. Mobile attribution is particularly challenging due to ATT, SKAdNetwork, and cross-platform gaps, necessitating a mobile measurement partner (MMP) for independent, deduplicated measurement. Clean attribution data is essential for AI-driven optimization—bad signals lead to bad decisions. Starting with position-based attribution and incrementality testing provides a practical foundation.
Cross-platform measurement resolves the common problem of fragmented, device-level reporting that inflates ROAS and misallocates budgets. By unifying customer identity across web, mobile, CTV, and other surfaces, marketers gain a single view of LTV and attribution. AppsFlyer provides this via CUID stitching and Product Line grouping, enabling real-time, deduplicated insights without manual BI work. Key benefits include accurate cross-platform ROAS, elimination of duplicate attribution, and reliable data for AI-driven optimization.
Digital banking ad impressions surpassed 50B quarterly with spend above $350M by Q1 2026, driven by mobile-first adoption. Neobanks like Nubank lead downloads, while traditional banks modernize apps. SeaBank's integration with Shopee exemplifies ecosystem-driven acquisition. For ad ops, key takeaways: prioritize mobile channels, leverage partnerships for scale, and balance reach with trust-building to sustain engagement.
TikTok from ByteDance has surpassed 1 billion installs globally, with 663 million in 2018. It is the 4th most downloaded non-game app, with 71.3 million new users in January 2019, 161% more than last year.
One person built, shipped, and marketed a mobile game in 14 days using AI tools, achieving 5,563 installs at $0.39 eCPI on $2,200 spend. MCPs (Model Context Protocol) were critical for agentic workflows. The AI agent CLAW managed ad campaigns via AppsFlyer MCP and BigQuery. Data Locker streamed raw data for analysis. Key takeaway: vendors must offer MCPs for fast, agentic data access; measurement stack (Data Locker, ROI 360, Creative Optimization) is essential for solo teams; human+AI beats AI alone.
