Consumer spending on mobile apps across the App Store and Google Play reached approximately $133 billion in 2021, representing 19.7% year-over-year growth from $111.1 billion in 2020, mirroring the pre-pandemic growth rate. The App Store accounted for $85.1 billion, up 17.7%, while Google Play grew 23.5% to $47.9 billion. Non-game app TikTok maintained dominance with $2.3 billion in consumer spending, while Google One topped Google Play revenue.
First-time installs remained relatively flat at 143.6 billion, with TikTok being the most downloaded app on the App Store and Facebook leading on Google Play. Mobile game spending grew 12.6% to $89.6 billion, representing 67.4% of total app spending, down from 71.7% in 2020 as non-game categories like Entertainment gained share. Games accounted for 61.5% of iOS revenue and 78% of Google Play revenue, with Honor of Kings and Coin Master as the top grossers on each platform.
Game installs declined slightly by 1.6% to 55.3 billion, with Garena Free Fire leading on Google Play and PUBG Mobile on the App Store. Overall, the mobile market normalized after the 2020 surge, with sustained growth in non-game categories.
App engagement is vital for retention and monetization. Key metrics include sessions, retention, and DAU/MAU. Strategies: effective onboarding, personalization, push notifications, and deep linking improve engagement and reduce churn.
Japan led per capita mobile spending at $149 in 2020-2021, up 18% YoY. Top 10 markets grew 22% YoY to $65.4B. Thailand saw largest per capita growth increase.
Eight mobile games, including PUBG Mobile, Honor of Kings, and Genshin Impact, each earned over $1 billion globally in 2021. The top two, PUBG Mobile and Honor of Kings, each generated $2.8 billion. This record surpasses 2020's five billion-dollar games.
Adjust has expanded store detection and verification across multiple app storefronts, making Store Type the primary dimension for identifying where an install originated rather than relying on platform or OS alone. For ad ops teams, this means campaign performance can now be analyzed at the store level across Huawei AppGallery, Xiaomi GetApps, Samsung Galaxy Store, Vivo Appstore, and Google Play variants, with independent verification of install origin. Newly detected stores are flagged in AppView with a direct route to configuration, and store-level data flows automatically into reporting, raw data, callbacks, and CSV exports, plus Conversion Rules via Store Rule conditions.
Top 500 apps reached record 91.7M MAU in Q2 2021, growing 8.4% Y/Y. Business apps led with 42% CAGR since Q1 2018. Entertainment apps average 29 minutes daily, shooters lead DAU in mobile games.
Programmatic advertising automates media buying using AI, enabling real-time ad sales and personalized targeting. It spans channels like display, video, and social, offering efficiency and lower costs.
Japan's finance app category is outperforming, with H1 2026 installs up 8% YoY and sessions up 40%—nearly 5x the install growth and well ahead of global figures (5% and 29%). Stock trading is the standout subvertical: installs +90% YoY and average session length climbing to 11.7 minutes, driven by NISA reforms and a retail investor resurgence. Retention is improving across the full 30-day curve (D1 17% to 19%, D30 7% to 8%). For ad ops teams, the takeaway is clear: prioritize measurement depth, re-engagement, and channel-level quality over top-of-funnel volume alone.
Adjust's Halloween 2025 data across six weeks shows the holiday window opens well before October 31 and differs by category and market. Entertainment installs peaked the weekend before Halloween (up 42–44% vs. summer baseline), with OTT/streaming and video content installs up 120% on October 25 and 300% YoY. Photo and video sessions instead spiked on Halloween night itself (+6% global vs. the four prior Fridays; Canada +15%, Germany +13%, U.K. +11%, U.S. +9%, Mexico +7%). Single global send dates miss market-level peaks, so ad ops should time creative, push, and budget shifts per market—especially in Mexico, where activity runs through Día de los Muertos.
