Crintech Toolkit
Offline developer tools
Free · Designed for iPad. Not verified for macOS.
18+ developer utilities in one app: JSON, regex, hashes, JWT, UUID, passwords, converters, an HTTP client, and a snippets library. No accounts. No tracking.
Crintech Toolkit bundles the utilities a developer (or any tinkerer) reaches for every day into a single app — no accounts, no ads, and nothing sent anywhere.
TEXT & DATA
• JSON formatter — format, minify, validate
• Regex tester — match highlighting and example patterns
• Text counter — words, characters, lines, paragraphs, reading time
• Text diff — compare two texts line by line
• Markdown preview — live rendering
ENCODERS
• Base64 — encode/decode, URL-safe variant
• URL encoder — percent-encoding, query mode
• Hashes — MD5, SHA-1, SHA-256, SHA-384, SHA-512
• HTML entities — encode/decode
• JWT decoder — inspect header and payload (local decode)
GENERATORS
• Lorem Ipsum — paragraphs, sentences, or words
• UUID generator — v4, in batches, uppercase or dashless
• Password generator — configurable, with entropy in bits
• QR generator — turn text, URLs, or vCards into a QR code
CONVERTERS
• Color converter — HEX ⇄ RGB ⇄ HSL with sliders
• Timestamp — Unix epoch ⇄ ISO 8601
• Number base — binary, octal, decimal, hexadecimal
• Case converter — camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, and more
NETWORK
• HTTP client — fire GET/POST/PUT/PATCH/DELETE requests at any REST API with custom headers and body, and inspect the response: status code, timing, and pretty-printed JSON. Ships with ready-to-run examples.
SNIPPETS
Save chunks of text, code, or tool output into a local library with tags and search. Everything stays on your iPhone — no cloud, no sync.
PRIVACY
• Works offline — the only network traffic is requests you fire yourself in the HTTP client
• No accounts, no sign-up
• No tracking, no telemetry, no ads
• No in-app purchases
Three languages (Spanish, English, Basque), light/dark mode, custom accent colors, and a "tip of the day" widget.
