ToneScope vs HashForge

ToneScope helps you see and understand sound in real time. ToneScope transforms complex audio into visual representations that are easy to interpret. Whether you're exploring music, investigating environmental noise, or simply curious about the sounds around you, ToneScope makes sound easier to understand. It uses a multirate FFT approach to achieve high frequency resolution at low frequencies while remaining efficient for real-time use on iOS. Users can analyze audio in real time or record sound locally and analyze it later. All processing is performed entirely on-device. Optional audio recordings are saved locally under user control. No data is transmitted, uploaded, or collected. Designed and developed by Newton Niu.

Generate and verify cryptographic hashes right on your device — 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 — no subscription. PRIVACY Everything is computed on your device. No account, no sign-in, no tracking, and nothing ever leaves your phone.
