Analysis

Across four major German shopping apps, users who spend the most time per active day are far more likely to complete a purchase within an eight-week window than those with the shortest sessions. The ratio is most dramatic on Temu — 18.3% of heavy users bought from the platform versus just 2.8% of light users, a 6.5× gap — but the pattern holds across all apps tracked in Germany in autumn 2026.

Engagement depth as a purchase signal

Vinted shows a similar dynamic: the top third by session length converted at 33.3%, against 6.4% in the bottom third — a 5.2× ratio consistent with how the resale format drives repeated, intent-laden browsing. Amazon's spread is narrower (54.4% vs. 33.3%), reflecting its role as a high-frequency utility app where even light users transact regularly. eBay sits in between, with a 3.4× gap (28.2% vs. 8.4%). The association between session depth and purchasing is real, but the direction is not settled: users who intend to buy likely linger longer, rather than longer sessions mechanically producing purchases. This distinction matters for marketers deciding whether to invest in in-app engagement features or simply reach more users.

Methodology

German Android users who opened at least one of the four shopping apps — Amazon, eBay, Vinted, or Temu — between September 1 and October 26, 2026, are grouped into terciles by their median foreground minutes per active day for each app individually. Purchase events within the same window are identified via matched email receipts from confirmed order confirmations. Purchase rate is the share of users in each tercile who completed at least one purchase from that app's merchant during the period. Results are weighted to German adults aged 18 and over by age, gender, region, education, and income. Purchase rates based on email receipts reflect confirmed orders and may undercount platforms where order confirmations are less consistently sent to the inbox used for tracking.
