App Annie: US Android users spent an average of 24.5 hours on TikTok in May vs. 22 hours on YouTube; in the UK, they spend 26 hours on TikTok and ~16 on YouTube

Context & Ripple Effects
This data point caps a two-year reversal. In a mid-2020 study of kids aged 4 to 15 across the US, UK, and Spain, YouTube still held the attention lead at 85 minutes a day versus TikTok's 80 — and TikTok's own internal deck claimed 17M Britons already spent over an hour daily on the app. Now App Annie's May figures show TikTok ahead of YouTube in average monthly hours per US Android user (24.5 vs. 22) and far ahead in the UK (~26 vs. ~16).
The reading matters because it lands on top of App Annie's earlier finding that daily app time crossed four hours per user in the US for the first time in Q1 ([[a:965072]]): attention isn't just growing, it's migrating toward short-form video within the same fixed budget of screen time.
First-order effects
- YouTube's mobile advertising pitch on Android now competes against an app where users log more monthly hours, weakening its default claim on video ad budgets in both markets.
- TikTok gains a third-party-measured engagement stat it can put in front of brand advertisers in the US and UK, its two largest Western ad markets by usage in this dataset.
Second-order effects
- Advertisers weighing reach versus engagement face a pricing question: if hours per user keep diverging, CPMs on short-form inventory get pressure-tested against YouTube's established video ad formats.
- Measurement becomes contested terrain — App Annie counts Android-only app time, so expect YouTube and rivals to counter with cross-platform or TV-screen numbers rather than concede the engagement framing.
Third-order effects
- If the pattern holds into demographics, linear TV loses the under-25 cohort first: UK regulator data later showed 15-24s spending more daily minutes on TikTok (57) than watching TV (53), while over-65s stayed with six hours of television.
- Attention measurement shifts from broadcast ratings and session counts toward per-user hours inside apps, making firms like App Annie arbiters of which platforms win ad budgets.
The trend: Video attention in Western markets is consolidating around short-form feeds, with per-user hours — not audience size — becoming the metric that decides ad spend.
