Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

Changed a DNS record? DNS Propagation shows in seconds whether public DNS resolvers already return the new value. Enter a domain, pick a record type and compare the answers of eight resolvers side by side, with response times, TTLs and how fresh each cached answer is. Built for webmasters, developers and IT admins moving a website, switching mail providers or changing nameservers.
Propagation check:
- Queries AdGuard, AliDNS, Cloudflare, DNS.SB, DNSPod, Google, NextDNS and RethinkDNS at the same time over DNS-over-HTTPS
- One clear status: all resolvers agree, mismatch, or error
- Record types: A, AAAA, CNAME, MX, TXT, NS, SOA and SRV
- Response time and TTL for every resolver, fastest first
TTL analysis:
- Queries the domain's own nameservers directly for the original TTL
- Shows how long each resolver has cached the answer and how fresh it still is, color-coded
- See at a glance when an old record will expire everywhere
History and gestures:
- Your last 50 lookups, grouped by day with their status
- Tap to expand a lookup, long press for all details
- Swipe right to check a domain again, swipe left to delete it
- Double-tap results to copy them, including the TTL analysis
Settings:
- Turn individual resolvers on or off
- Request timeout from 1 to 30 seconds
- TTL analysis on or off
- Light, Dark and System appearance
- Works on iPhone and iPad, with a sidebar on iPad
What’s new
Release notes for the latest version, as written by the developer.
Checking a domain again now always queries every DNS resolver. Before, a check repeated within a few minutes could show the answers stored on your device from the previous check, with a response time of 0.00s.
