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.

About this app
Text from the App Store listing.
PeekLens Essential is a private, portable UN/EDIFACT workbench for anyone who reads, builds or troubleshoots EDI messages: EDI analysts, integration developers, customs and logistics teams, and learners.
Paste, import or share a message and PeekLens checks its syntax against the public UN/EDIFACT directory it declares, then explains every finding in plain language. Everything happens on your device. No account, no sign-in, no tracking.
INSPECT
- Check envelope and message syntax: UNB/UNZ, UNH/UNT, segment counts, mandatory segments and elements, composite structure, data types and lengths
- Clear findings that show where the issue is, what the directory expects and which rule produced it
- Explore any message segment by segment, with names and meanings for every element
REFERENCE
- Browse messages and segments for each supported release
- See how composites, elements and segment groups are defined, offline
COMPARE
- Compare a message type between two releases and see which segments were added, changed or removed, including nested segment groups
SHARE SAFELY
- Mask party IDs, references and other sensitive values before sharing, with a preview of exactly what will be shared
- Export a Syntax Inspection Report to share with colleagues or partners
- Import files or send messages to PeekLens from Mail, Files and other apps
LEARN
- Built-in guides and concepts for the essentials of UN/EDIFACT structure
14 PUBLIC UN/EDIFACT RELEASES INCLUDED
92.1, D.95B, D.96A, D.97A, D.98B, D.99B, D.00A, D.00B, D.01B, D.13B, D.18A, D.20A, D.20B and D.24A, built from the official EDIFACT directory archives. All releases are included with your purchase and work fully offline.
DESIGNED FOR IPHONE AND IPAD
One app for both, with a layout that makes use of the larger iPad screen.
PRIVATE BY DESIGN
Your messages are inspected entirely on your device. PeekLens has no account, no analytics and does not send your messages anywhere. Inspection history is optional and stays on your device.
IMPORTANT
PeekLens performs syntax-only inspection based on the public EDIFACT directories. It does not check business rules, implementation guides (MIGs), trading-partner requirements or regulatory and customs acceptance, and it is not an official validator. A clean result does not guarantee that a message will be accepted by any partner or authority.
