Read full description

WhatChanged is a file and folder comparison app built to answer one practical question: what changed between these two copies? Compare two files or two folders on iPhone, iPad, and Mac and get a clear summary of added, removed, modified, renamed, and identical items. Use optional SHA-256 verification when metadata alone is not enough. On iPhone and iPad, start inside the app or send exactly two files from Files straight to WhatChanged. It is useful for backups, exports, cloud-drive copies, builds, and any “did this transfer match?” check. ◼ File and folder comparison • Compare two files or two folders as Left and Right • Review added, removed, modified, renamed, and identical items • Use smart ignore rules for hidden items, extensions, names, and patterns • Ignore line-ending or whitespace-only changes when appropriate • Preview supported files, keep recent comparisons, and export or share reports • Verify content with optional SHA-256 and cached re-checks • Use the app in 25 languages, with an optional in-app language override ◼ From the share sheet In Files, or another app that can share files, select exactly two files. Tap Share → WhatChanged. The comparison opens automatically. Tip: The extension is intended for file-to-file comparison. To compare folders, open the main app. ◼ Safe Merge Run a folder comparison, open Safe Merge, and choose a main rule: Newest, Oldest, Smallest (New), Smallest (Old), Biggest (New), or Biggest (Old). The Safe Merge Assistant shows selected items, recommendations, conflicts, blocking issues, output details, and safety checks before anything is copied. For individual output paths, you can keep the main Merge Rule or choose Left or Right. Recommended continues to show what the main rule would choose, while Selected shows what will actually be copied. The “+ Custom” indicator appears whenever exceptions are active. WhatChanged recalculates the plan and verifies it again before copying. Custom merges use a clearly named output folder, such as “Safe Merge by WhatChanged (Newest + Custom).” Successful merges include a generated README describing the compared folders, main rule, custom selections, copied items, output paths, counts, and safety notes. ◼ Quick text checks Use Direct Text Compare, supported text files, or folder-pair text results for convenient text checks. Copy a unified-diff-style result, search with Find in Diff, move between matches, highlight rows, and review Diff Summary counts. These text tools are included for quick comparison inside a file-and-folder utility. WhatChanged is not designed as a full drafting workspace. ◼ Looking for a dedicated text workspace? DiffDraft is designed specifically for comparing text versions and composing a clean final draft in a row-aware workspace. Source rows, draft rows, manual rows, and intentional gaps stay visually aligned, helping long reviews remain stable and trustworthy while you cherry-pick, edit, and continue later. View DiffDraft on the App Store: https://apps.apple.com/us/app/diffdraft/id6779625050 ◼ Safe by design WhatChanged does not modify or delete your originals. Comparisons are read-only. Safe Merge writes only to a new output folder after you confirm the merge and every required safety check passes. ◼ Official website Product information, support, privacy details, and terms are available here: https://hazybyte.studio/whatchanged/ Requires iOS 16.6 or later.

Read full description

PCAP Analyzer opens and analyzes .pcap and .pcapng network captures right on your iPhone, iPad, and Mac, with no desktop required. Troubleshoot a flaky connection, investigate a security incident, or learn how networks really work, with a fast, deep, and clear packet analyzer in your pocket. Open captures created by tcpdump, tshark, and any standard pcap or pcapng tool, and read the wire like a page. DEEP PROTOCOL DECODING Every frame is dissected down to the field: Ethernet and VLAN, IPv4, IPv6, TCP, UDP, ICMP, ICMPv6, IGMP, ARP, DNS, mDNS, LLMNR, DHCP, HTTP, HTTP/2, TLS, DTLS, QUIC, SMB2, SNMP, NTP, RADIUS, TFTP, MQTT, SCTP, GRE, ESP, and NetFlow/IPFIX. A clean, tappable detail tree and a full hex view show every byte. TLS FINGERPRINTING, JA3 AND JA4 PCAP Analyzer computes JA3 and JA4 client fingerprints natively, and even decrypts QUIC Initial packets to recover the SNI and fingerprints, analysis that usually needs desktop plugins. FIND THE PROBLEM FAST • Color coded packets, so retransmissions, resets, errors, and stalls stand out • Expert diagnostics: TCP retransmissions, duplicate ACKs, zero window stalls, connection resets, HTTP errors, and DNS failures • Threat detection: port and host scans, suspicious C2 and backdoor ports, possible DNS tunneling, and cleartext credentials POWERFUL DISPLAY FILTER A real, field aware filter language with autocomplete and saved filters: tcp.port == 443, tls.sni contains "example", tcp.analysis.zero_window, dns or http. Tap any field in a packet to filter by it instantly. STATISTICS AND VISUALS Conversations, Endpoints, Protocol Hierarchy, a network topology map, an I/O graph, Follow Stream with a TCP sequence and time graph, and automatic name resolution, so you see hostnames instead of raw IP addresses. ON-DEVICE AI On supported iPhones with Apple Intelligence, an on device model summarizes a capture in plain language and turns plain English requests into filters, like "show failed connections". It runs entirely on your device, and your capture never leaves your phone. BUILT FOR BIG CAPTURES A native streaming engine opens very large captures without running out of memory, files that crash other mobile viewers. PRIVATE BY DESIGN Everything happens on your device. PCAP Analyzer reads saved files only, captures no live traffic, needs no special permissions, and never uploads your data.
