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.
