Summary
The mobile app landscape continues to expand, with global installs up 13% year-over-year and sessions up 5% in H1 2026, defying industry concerns about saturation and rising costs. Monthly trends followed seasonal patterns, with May as the peak month. In gaming, overall sessions grew 6%, but casual games led with a 55% increase, followed by arcade (19%), match (18%), sports (15%), and hybrid casual (14%).
Hyper casual and strategy also posted double-digit growth, building on strong 2025 performances. For e-commerce, install day engagement improved in every region: North America rose to 1.34, MENA to 1.38, APAC to 1.42, Europe to 1.37, and LATAM to 1.4. Finance apps showed a stark divergence between installs (+5% YoY) and sessions (+29% YoY), indicating that users are returning more frequently, with March being the strongest month for both metrics.
These trends suggest that ad ops decision-makers should focus on high-engagement genres like casual gaming, optimize for install day to boost early retention, and leverage finance's strong session growth potential. With November and December historically showing elevated installs and e-commerce sessions, the second half of 2026 promises further opportunities, but success depends on reliable measurement and data-driven budget allocation.
Analyst Note
What's notable here is the continued decoupling of install and session growth across verticals. Global installs rose 13%, but finance sessions grew at nearly six times the rate of installs — a gap that underscores how engagement is becoming a more reliable success metric in the post-SKAN era. Similarly, e-commerce install-day engagement improved in every region, with LATAM posting gains for three consecutive years.
These aren't dramatic shifts, but they signal that early retention is still improvable even in mature categories. The broader industry signal: despite years of talk about saturation, privacy headwinds, and higher acquisition costs, overall app activity is still expanding. For UA and monetization teams, the key implication is that vertical-specific benchmarks matter far more than global averages.
Casual gaming's 55% session growth exists in a completely different context than strategy or hyper-casual. With H2 typically driven by e-commerce seasonality, the data suggests that engagement metrics — not just installs — will be the differentiator in year-end planning. Worth watching whether the June uplift in sessions carries into the holiday months, and whether finance's strong retention persists beyond the H1 window.

AdjustJapan’s finance app growth in 2026 | Adjust
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.
AdjustThe 4R framework for understanding deep linking | Adjust
Karthik Kannan distills deep linking into a practical 4R framework: Remember, Reach, Retrieve, Route. For ad ops teams, the key insight is that campaign context must survive the click-to-app journey. Adjust TrueLink captures link parameters on click; the user is then guided into the app via Universal Links, Android App Links, URI schemes, app stores, or web-to-app flows. On SDK init, the app session is matched and attributed to the click, then link data is passed to the app for routing. Decision-makers should ensure deep link paths, campaign parameters, attribution matching, and fallback journeys are tested to protect measurement and user experience.
AdjustHalloween app trends: Insights for your 2026 campaign | Adjust
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.

AdjustHow mobile app marketers should approach CTV | Adjust
CTV has become performance-ready for app marketers. Recent acquisitions (Fox/Roku, Walmart/Vibe) signal a shift to self-serve, measurable channels. Marketers can reuse existing UA creative instead of producing TV ads. QR codes drive direct response, but halo effects often matter more. Start with small, additive test budgets and measure assists/incrementality to understand true impact. CTV offers a way to find incremental users and diversify beyond paid social.
AdjustMeasure installs across more app stores | Adjust
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.
