Phasm vs Mathify

Hidden in plain sight. Phasm hides encrypted messages and files inside ordinary photos. The photo looks the same, but only someone with the right passphrase can read what it carries. TWO MODES • Armor — for photos you send through messengers. Short messages use Fortress, which survives cropping, rotating, mirroring, resizing and the 4:5 crop of social apps, plus the recompression of popular messengers. Longer messages use Standard, which survives recompression and resizing. Phasm picks the right one and shows which it used. • Ghost — for stealth. Ghost places its changes where the photo already has texture, so detection tools struggle to tell it from an untouched photo. Send Ghost photos as files: any recompression erases them. Ghost can carry file attachments too, including up to three photos. HOW HIDDEN IS GHOST? The capacity bar tells you. While your message stays in the green zone, Ghost is near-undetectable: in our measurements, every detector we tried, including deep-learning detectors on full-size photos, did no better than guessing. Larger messages are easier to detect, and the bar shows it by turning yellow, then red. When it matters, keep it green. DEEP COVER Use a photo from Phasm's own camera, which captures uncompressed, or a PNG, and Deep Cover starts by itself: Phasm writes the JPEG from the original pixels, so Ghost hides better and holds about 25% more. MADE FOR YOUR MESSENGER In Armor, pick the app you will send with, and Phasm prepares the photo at the size that app uses. For a 4:5 social feed, the preview shows what the crop will keep. ONE PHOTO, SEVERAL MESSAGES Shadow messages hide several independent messages in one Ghost photo, each with its own passphrase. Without its passphrase, a shadow message has no header or marker to find. Phasm tells you which passphrase is the safe one to reveal. SERIOUS ENCRYPTION • AES-256-GCM-SIV encryption on every message, always on. • Argon2id key derivation, built to slow down brute-force and GPU attacks. • 256-bit keys, considered safe against quantum computers. • No backdoors, no key escrow. You hold the only key. PRIVATE BY DESIGN • Everything runs on your device. Nothing is uploaded unless you create a share link. • No account, no sign-up, no ads. Anonymous usage statistics, which you can turn off in Settings. • The magic wand removes location and camera details and gives the photo a neutral file name. • The engine is open source (Rust), so anyone can check it. SHARE YOUR WAY • Send Armor photos as normal photos in your messenger. • Send Ghost photos as files: AirDrop, Mail, or as a document in your messenger. • phasm.link: share a short link, and recipients decode in their browser or the App Clip, with no install. BUILT FOR iPHONE, iPAD AND iPHONE DUO • Native app, with a side-by-side layout on iPad and on the Duo's inner display. • Takes JPEG, PNG, HEIC, WebP and GIF; saves a JPEG. • 41 languages. HONEST ABOUT LIMITATIONS • Ghost does not survive recompression or resizing. Send it as a file. • Standard does not survive crops or rotation. For social apps that crop photos, keep the message short so Phasm uses Fortress. • Some apps shrink photos heavily and are not tested. Assume they destroy the message. • Capacity depends on the photo: larger, more detailed photos carry more. • Steganography hides that a message exists. Encryption protects what it says. Phasm does both.

Mathify is a fast, focused calculator for iPhone and iPad. Ask the AI calculator a question in plain language or open a dedicated native calculator for math, finance, conversions, dates, fitness, business, and more. Native calculations run on-device, update as you type, and keep long expressions easy to review without taking over the screen. AI answers show the formula, working, assumptions, and a clear result. Your history stays on your device. The app ships without ads, accounts, tracking SDKs, or blog content. Available in the same 28 languages as Mathify web; the AI calculator answers in your language, and some calculator field labels are still English while translation continues. General wellness estimates are clearly marked as educational planning tools and are not medical advice. Clinical dosing, medication, vaccination, blood-alcohol, drug half-life, and gambling tools are not included in this launch.
