Paytools vs AppMoney

Paytools is an offline payment-engineering workbench for developers, QA engineers, integrators, students, and fintech teams. Decode and inspect common payment-message structures, explore field definitions, convert technical data, and keep essential payment references close at hand. Processing happens locally on your device, so pasted messages and imported files are not uploaded to a server. PAYMENT TOOLS • Inspect ISO 8583 MTIs, bitmaps, and present data elements • Decode and build primary and secondary bitmaps • Parse BER-TLV data and identify common EMV tags • Recognize SWIFT MT blocks and ISO 20022 XML messages • Convert between HEX, ASCII, decimal, binary, and packed BCD • Validate synthetic card numbers with the Luhn algorithm • Compose synthetic Track 2 and ISO-0 PIN-block test data • Use development utilities for XOR and DES odd parity KNOWLEDGE LIBRARY • Search all 128 ISO 8583 data elements • Learn ISO 8583:1987, 1993, and 2003 MTI concepts • Follow authorization from merchant to acquirer, scheme, and issuer • Understand STIP, advice, reversal, clearing, and settlement flows • Review ISO 20022 message families and validation concepts • Study EMV transaction and cryptogram terminology CODES AND FIELDS Search operational response-code references for common ISO profiles, Visa, Mastercard, UnionPay/UPI, 3-D Secure, and gateway HTTP outcomes. Open any ISO field for its purpose, format, and implementation notes, including an expanded guide to DE22 POS Entry Mode. PRIVATE BY DESIGN Paytools has no account requirement and no cloud processing. Use synthetic or appropriately masked test data. Production payment formats and code meanings can vary by network, region, product, and specification release. Paytools is an independent educational and development utility. It is not affiliated with or endorsed by any payment network. Formal certification and production processing require the current authorized specifications, test packs, approved cryptographic systems, and applicable security controls.

See what any app earns. AppMoney turns the store into a searchable market. Look up any of 1.8 million apps and see its estimated monthly revenue and downloads, how both moved against last month, its rating, its top markets, and when it last shipped. BROWSE THE MARKET - Top grossing and most downloaded - Fastest growing by revenue and by installs, with the figures behind the percentage - Newly released apps, and pre-orders before they land - Reorder the collections you care about and hide the ones you do not SEARCH AND FILTER Filter 1.8 million apps by category, revenue, downloads, growth, rating, review count and release date, and sort by any of them. TRACK WHAT MATTERS Bookmark apps to your watchlist and see revenue, installs and rating side by side. Add an app straight from Safari with the share sheet, without opening AppMoney first. ABOUT THE FIGURES Revenue and download figures are third-party estimates for the last 30 days, not developer-reported numbers. Where a figure falls below what the source can resolve, AppMoney shows the ceiling, such as under 5,000 dollars a month, rather than inventing a number.
