SensorTowerThe Size of iPhone’s Top Apps Has Increased by 1,000% in Four Years
Summary
The top 10 most installed U.S. iPhone apps have grown from 164 MB in May 2013 to about 1.9 GB in May 2017, a 12x increase. Snapchat saw the highest growth at 50x, from 4 MB to 203 MB.
Facebook became the largest at 388 MB. Apple's 2015 raise of the app size cap to 4 GB and iOS 10's acceleration of growth are key factors. Competition drives feature additions, while games like Injustice 2 reach 1 GB.
iOS 11 introduces smarter storage with app offloading.

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.
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.
AppsFlyerMeasuring app campaigns on Facebook: Everything you need to know
Facebook offers two measurement options: using an MMP or Facebook's own tools. MMPs provide cross-campaign attribution, avoid double attribution, and grant user-level data access. Choosing an MMP is recommended for accuracy and independence.
AppsFlyerCreative optimization: Why your best video ad fails as a static image
AppsFlyer’s 2026 creative data shows video and static image ads reward opposite creative qualities, so ad ops teams should plan, budget, and test them separately. Video spend is concentrating: gaming’s top 2% of video creatives captured 60.7% of spend, up from 53.5%, while image spend spread out. Top spenders are testing far more variations, widening the testing gap. Action/Strategy and Puzzle/Lifestyle show format-specific tone and social-proof reversals; Finance is the exception. Teams should use AI-assisted variation, analyze video winners deeply, keep broad image testing, and measure performance at attribute level.
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.
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.
AppsFlyerCracking the 2026 Holiday Season: A Data-Backed Playbook for Marketing Leaders
Q4 2026 planning should treat peak shopping as a compressed event, not a week. Black Friday/Cyber Monday purchase lift runs 2–3x install lift, so ad ops must schedule by daypart and hour. Singles Day is not global: Brazil, UAE and Spain show real lift, while US/France barely react. CPI spikes hardest in supposedly cheap markets—Spain’s CPI rose nearly 50%. Remarketing already drives 65–92% of non-organic spend and rises during peak. Deep linking is critical: deep-linked users are ~2x more likely to purchase and spend nearly 3x more. Benchmark market CPI, shift budget to remarketing, and connect every entry point.
