Summary
Screenshot orientation is crucial for App Store Optimization because screenshots are among the first elements users notice after finding an app. On iPhone, portrait screenshots are optimal because they display correctly by default, making it easier for users to scan quickly. If landscape screenshots are used on iPhone, they are flipped to portrait orientation, which can hinder quick comprehension.
On iPad, landscape screenshots look more impressive in both search and detail views, allowing two full screenshots to be viewed simultaneously. For desktop and web iTunes, iPhone screenshots are shown first, and landscape screenshots appear in landscape orientation, which may break uniformity. Portrait screenshots allow two full images to be visible on iTunes, while landscape screenshots in the second position may get cut off.
However, these are guidelines, not rules. Experimenting with portrait screenshots on iPad can reveal part of a third screenshot, providing more space to convince users. To see what competitors are doing, check App Profile Pages and the Update Timeline tab.
For example, GSN Casino recently switched all iPhone screenshots to portrait. Ultimately, testing is key, but considering these factors can help increase downloads.

AppsFlyerMarketing attribution: what it is and how to measure it
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.
AppsFlyerWhere European Finance Apps Win or Lose Users
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.

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.
