InfoCard vs DataStamp

InfoCard is a simple app for iOS and macOS which provides information about anything you can paste, drop, open, or share. Drag files, folders, volumes, and content; Paste images, text, URLs, and anything else on the clipboard; Open files on local or cloud storage; and Share content on iOS! InfoCard will get all the information: - QuickLook previews - File attributes for any files - Spotlight metadata - Image metadata (EXIF, TIFF, PNG, & c.) - HTTP headers for URLs - Cryptographic hash codes (MD5, SHA1, SHA2) - PDF file attributes - x509 Certificate details - and more! InfoCard is Great for Photographers & Videographers: - Detailed Image Metadata - Audio and Video Metadata - Easily copy item info as text InfoCard is Helpful for iOS and macOS Developers: - Verify you apps pasteboard, and drag and drop functionality - Improve integration with other apps by better understanding the data they provide InfoCard is Enlightening for Power Users: - Get detailed information about your apps, files, amd volume - See what apps are putting on the clipboard or sharing - Peek around and see what's what

DataStamp is a local-first proof vault for creating verifiable timestamps for text, photos, screenshots, receipts, contracts, and files. The app computes a SHA-256 hash on your device, requests an OpenTimestamps proof, and lets you keep a portable record that can later be verified against Bitcoin anchoring. Your original content stays under your control; the proof is based on the hash, not on uploading the private document itself. What DataStamp does: • Create timestamp proofs for text, images, and files • Verify existing OpenTimestamps (.ots) proofs • Track pending and confirmed proofs • Organize evidence with folders and tags • Export/share proof material when needed • Use widgets and background checks for pending confirmations • Optionally sync your own records through your private iCloud account DataStamp is designed for people who want defensible records without depending on a central account, proprietary server, or mutable database. It is useful for preserving proof of existence for notes, creative drafts, legal or financial records, screenshots, business documents, research artifacts, and other digital evidence. OpenTimestamps is an open protocol for timestamping data with Bitcoin. DataStamp provides a polished iOS workflow around that protocol while keeping the app local-first and privacy-conscious.
