& FAQ.
AppRoster is built by one person. Email lands on a real inbox, and gets a real reply — usually within a day or two.
Some countries are missing from my comparison table. Why?
AppRoster only persists countries where the app actually has at least one rating. If Vanuatu shows nothing for your app, it's because Apple's iTunes API returns zero ratings there — there's no data to surface. Tap refresh; if the missing storefront gained ratings since you added the app, the background long-tail discovery will pick it up within ~30 seconds and the row will appear.
Why is the histogram different from the rating count?
Apple's RSS feed only includes reviews with written text — not star-only ratings. The headline "RATINGS" number includes everyone; the histogram is built from the most recent ~150 text reviews per country (Apple's RSS limit). For storefronts with a lot of silent star-tappers the histogram will be a sample, not a census.
Where is my data stored? Do you have an account system?
AppRoster has no account, no login, no server. Everything — the apps you track, the cached snapshots, the reviews you've seen — lives in a local SwiftData store on your iPhone alone. Delete the App and every byte goes with it. See the Privacy Policy for the full picture.
Is Pro a subscription?
Not anymore — since v1.1.2, Pro is a single one-time purchase. Nothing renews. If you subscribed before v1.1.2, your subscription keeps unlocking Pro; cancel it anytime in iPhone Settings → your name → Subscriptions → AppRoster Pro. Apple, not us, runs the billing — deleting AppRoster itself does not cancel an active subscription.
Why doesn't AppRoster show ratings for unreleased / unpublished apps?
AppRoster reads Apple's public iTunes endpoints. If your app is in TestFlight or unreleased to the public App Store, it won't appear in iTunes Search results and we can't fetch metadata for it. The app must be live in at least one storefront.
I think I hit Apple's rate limit. What should I do?
AppRoster has an automatic exponential-backoff throttle — when Apple returns a 429 rate-limit response, the app waits 1s, 2s, 4s, up to 30s before retrying, and lifts the throttle after 10 successful calls in a row. You'll see slower scans but no errors. If a refresh seems stuck, wait a minute and try again.
How do I get a refund?
Refunds for App Store purchases are handled entirely by Apple. Visit reportaproblem.apple.com, sign in with your Apple ID, find the AppRoster transaction, and request a refund. We don't have access to your billing history and can't issue refunds on Apple's behalf.
Can I request a feature?
Yes — email zhiii0x@gmail.com with the subject line starting "[Feature]". One developer reads every message; you'll get a real reply. No promises on shipping, but every suggestion is read.
