FlowSpy

Read full description

FlowSpy is an AI-powered network debugging tool for developers, QA engineers, and security researchers. Capture, inspect, filter, replay, analyze, and export HTTP/HTTPS traffic directly on iPhone and iPad. [LOCAL VPN CAPTURE] FlowSpy uses a local VPN and on-device proxy to capture HTTP/HTTPS traffic. The VPN is only used for local network debugging. It does not provide remote VPN service, anonymization, censorship circumvention, network acceleration, or remote traffic forwarding. [HTTPS INSPECTION AND CERTIFICATE GUIDE] To inspect HTTPS payloads, users must explicitly install and trust a self-signed CA certificate generated locally on the device. FlowSpy provides guided setup steps, and users can stop capture, remove the VPN configuration, or clear certificates at any time. [AI ANALYSIS] Local rule analysis is available by default and does not upload data. Pro cloud AI analysis only runs when the user explicitly starts analysis for selected traffic. It helps identify anomalous requests, performance issues, security risks, and suggested fixes. [DEVELOPER WORKFLOW] β€’ Browse requests grouped by domain β€’ Filter by method, status code, host, protocol, and content type β€’ Inspect headers, body, cookies, timing, and response payloads β€’ Replay requests and edit parameters before replaying β€’ Export HAR, JSON, CSV, and cURL β€’ Scan token, cookie, and privacy-field risks [PRIVACY FIRST] Captured traffic is stored locally on the device by default. FlowSpy does not include advertising SDKs and does not track users across apps or websites. Use packet capture and HTTPS inspection only on devices, apps, websites, and networks you are authorized to inspect.

About

Dos View

Features
Read full description

Dos View shows what is really inside a file. Open anything β€” a document, a photo, an app bundle, a log, a disk image β€” and read it byte by byte, in the look of a classic DOS text-mode viewer. THREE VIEWS β€’ HEX β€” offsets, bytes and their characters side by side β€’ BIN β€” every byte as eight bits β€’ TXT β€” the file as text, with line wrap and record formatting dosview guesses the right view and code page from the file's first bytes, and you can switch with one tap. 20 CODE PAGES CP437, CP850, CP852, CP866, CP1250, CP1251, CP1252, ISO-8859-1, -2, -5 and -15, KOI8-R, KOI8-U, MacRoman, MacCyrillic, UTF-8, UTF-16LE and UTF-16BE. Old DOS texts with box-drawing frames and Cyrillic finally look right. SEARCH AND NAVIGATION β€’ Find text, or bytes with an x: pattern β€” x:89 ?? 4E 47, where ?? matches any byte β€’ Go to any offset, in hex or decimal β€’ Format: split the data into records by a separator and see its bytes marked β€’ Highlight of matches, the byte under the cursor always shown below FILES OF ANY SIZE The viewer core is written in Rust and reads only what is on screen, so a file of many gigabytes opens at once and scrolls to its end without waiting. MADE FOR TOUCH Drag to scroll, pinch to zoom, drag the offset column to narrow it, drag the text column to set the bytes per line, tap a byte to put the cursor on it, hold for the code page list. Everything you set is remembered. With a hardware keyboard you get the classic keys: F7 Find, F8 next match, F5 Go to and more. OPEN FROM ANYWHERE Open from Files, or pick a photo or video from the gallery. Or send a file to dosview from any app with "Open in…" and the share sheet β€” even plain text or a link, to see its UTF-8 bytes. ACCESSIBLE High-contrast palette, support for VoiceOver, Bold Text, Reduce Motion and larger text. Available in 46 languages. PRIVATE No accounts, no ads, no tracking, no network. Your files never leave the device.
