- From Developer Tools grossing #93
Unverified model estimate. Neither Apple nor the developer has published this number, and the real figure can be several times higher or lower. Low confidence: the real figure can be a band higher or lower.
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.

PostX is a powerful yet simple API client for iPhone and iPad for working with REST APIs, HTTP APIs, and even occasional SOAP APIs. Use this REST API client and HTTP API client to quickly build requests, inspect responses, and iterate on your backend without needing a desktop tool.
Features of PostX
• HTTP/HTTPS methods
Send requests with GET, POST, PUT, DELETE, PATCH, and more so you can cover most modern REST and HTTP APIs in one API client.
• Custom parameters
Add query parameters with key, value, and descriptions to keep complex endpoints organized and reusable in your API-client testing workflow.
• Authorization
Use Basic, Bearer/JWT, and OAuth-style authentication to connect securely to protected APIs directly from this REST API client for iOS.
• Headers
Add custom headers, with common ones like Content-Type and User-Agent ready for quick setup when using this HTTP API client on iPhone and iPad.
• Body formats
Build request bodies in raw, binary, GraphQL, form-data, and x-www-form-urlencoded formats to handle most real-world REST and HTTP API scenarios.
• Scripts
Insert pre-request and post-response scripts to handle tokens, variables, and simple checks without leaving your API client.
• Response viewer
View status codes, headers, and prettified JSON to understand and debug API behavior faster during API-client testing.
• History
Automatically save requests and responses so you can rerun, tweak, and reuse them whenever you need inside your API client for iOS.
• Workspaces
Create workspaces to organize APIs by project, service, or environment so you can keep related requests grouped and easy to access.

How the score worksGap check · UK
Is this US chart app missing in UK?
It showed up on a UK chart in the last 30 days, so it is not a gap.
Store not checked yet
This is a candidate, not a verdict. Charts show at most 100 apps, so not charting does not mean no demand. Check the UK store before you decide.
