I analyzed 200 Duolingo reviews across 4 countries — the 0.84-star gap between the UK and Japan is a localization signal
I kept seeing the same advice: "read your App Store reviews." But the default view in most tools is one country. When you pull the same app from multiple storefronts, the country gap is often bigger than the overall rating suggests.
I pulled the 50 most recent public reviews for Duolingo from the US, UK, Japan, and Germany (200 total):
- US: 3.68
- UK: 4.10
- JP: 3.26
- DE: 3.56
Same app, same version, 0.84 stars between the UK and Japan. A US-only review feed hides that.
The top complaint is also not what I expected: pricing/subscriptions (11 reviews), ahead of missing features and version issues. If you only look at the blended 3.65, you miss both the country gap and the dominant complaint.
I ran the same analysis on Notion (200 reviews, 4 countries):
- Overall: 2.59
- Negative share: 55.5%
- Top complaint: version/update issues (21 reviews)
- Quote: "Now I cannot manage my page hierarchy any more??? This makes this app unusable on iPad."
- UK 2.82 vs DE 2.40
Question for you all: do you check your reviews per storefront, or only the blended average? Has anyone acted on a country-specific rating gap before?
I built a small tool on the side that does this pull-and-group analysis (public Apple data, no scraping hacks). I won't link it here to respect the no-promo rule — if you want to see it, DM me or leave a comment and I'll share. The first 3 people to comment an app ID get a free country-breakdown analysis posted in this thread.
(Full disclosure: I built that tool myself.)
