Verdict: which one has fewer problems?

Across the latest 600 App Store reviews we collected, the two apps have a similar share of reviews with a complaint (Skyscanner 45%, KAYAK 45%). The biggest single difference is in performance (slowness, battery, storage) complaints: 11% of Skyscanner reviews mention them, vs 3% for KAYAK. Each app's own biggest complaint theme: Skyscanner, bugs (81 reviews); KAYAK, bugs (72 reviews). Average star rating in the samples ranges from 3.18★ (KAYAK) to 3.27★ (Skyscanner). Time span of each sample: Skyscanner 386 days (2025-10-02 to 2026-10-22); KAYAK 3096 days (2018-04-24 to 2026-10-14). Because Skyscanner's sample covers a much shorter period, a single recent update or outage weighs more heavily in its numbers. Samples that reach back many months (fewer reviews per day) show long-running issues rather than the effect of one recent update.
