XHelper vs Blue Van Clef for Mobile

XHelper is a fast, private toolkit for the small conversions developers do all day. Paste anything and XHelper recognizes it — a JWT, JSON, a Unix timestamp, a UUID, a URL, a color, a number, or Base64 — and opens the right tool with your input already filled in. ENCODING • Base64 — Encode and decode text and files, with a URL-safe option and image previews for decoded data. • URL — Percent-encode and decode, and see every part of a URL plus its query parameters. • JWT — Decode the header, payload and claims, see when a token expires, and verify HS256, HS384 and HS512 signatures. HASH • MD5, SHA-1, SHA-256, SHA-384 and SHA-512 for text or files, with optional HMAC. Large files are hashed in chunks. FORMAT • JSON — Pretty-print with 2 spaces, 4 spaces or tabs, minify, sort keys, and get errors with the exact line and column. GENERATE • UUID — Create v4 or time-ordered v7 UUIDs in batches, with uppercase, hyphen and brace options. Inspect any UUID, including the timestamp inside a v7. CONVERT • Epoch — Unix timestamps in seconds, milliseconds, microseconds or nanoseconds to UTC, local time, ISO 8601 and relative dates, and back again. • Number Base — Binary, octal, decimal and hex, including negative numbers. • Color — Hex, RGB and HSL, plus ready-to-paste SwiftUI, UIKit and AppKit code. TEXT • Regex Tester — Live match highlighting, capture groups and flags. • Text Diff — Compare two blocks of text line by line. • Text Tools — camelCase, snake_case, kebab-case and more; sort, reverse and de-duplicate lines; count characters, words, lines and bytes. WORKS EVERYWHERE • Shortcuts, Siri and Spotlight — Encode and decode Base64 and URLs, hash text, format JSON, decode JWTs, generate UUIDs, convert timestamps and change case without opening the app. • Mac Services — Select text in any Mac app and use Services → XHelper to encode, decode, format JSON or change case in place. • A native app for Mac, iPhone and iPad, with a searchable sidebar and keyboard shortcuts on Mac. PRIVATE BY DESIGN XHelper works completely offline. Nothing you paste ever leaves your device, and there's no tracking of any kind.

Once connected to a device, you can do a "drill-down" discovery of the device's services, characteristics, and descriptors. The app is designed to respect Accessibility (VoiceOver and Increased Contrast), as well as Dark Mode. This is a 100% open-source app, with the code licensed as MIT. It uses the BlueThoth Framework (A Bluetooth SDK), which is also 100% open-source.
