Generate and verify cryptographic hashes right on your device β fast, clean, and completely offline. Type or paste any text, or pick a file, and get every common digest at once: MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Tap any result to copy it. Checking a download or a signature? Paste the expected hash and see an instant match or mismatch. HOW IT WORKS Enter your text or choose a file and the hashes compute immediately. Copy the one you need with a tap, or drop an expected value into the verify bar to confirm two files or strings are identical. Recent hashes are saved so you can find them again. FEATURES - MD5, SHA-1, SHA-256, SHA-384, and SHA-512 in one view - Hash both text and files - Verify against an expected hash with a live match indicator - One-tap copy for any result - Recent history so nothing gets lost - Clean, calm interface built for quick checks PRO A one-time unlock adds an HMAC generator to sign messages with a secret key (MD5 through SHA-512), unlimited history instead of the most recent entries, and CSV export of your full hash log. Buy once and keep it forever β no subscription. PRIVACY Everything is computed on your device. No account, no sign-in, no tracking, and nothing ever leaves your phone.

Verdict
The clearest difference is in-app purchases: OffDays Alarm at none against HashForge's 1. HashForge's advantage is ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
