Sun Focus vs Phasm

Locate the sun wherever you are on Earth, anytime, by any weather. Find out what the sun path is any date, any location on Earth with an intuitive interface. Supports augmented reality (AR) and widgets. Use this app to: • plan your next sunset photo or sunrise photo; • find the time the sun illuminates a specific side of a building (for a photo shoot); • estimate sun exposure when looking for a new property; • which side of the hotel your room should be for your next holidays; • learn more about the sun path in the sky and seasons; • study archaeoastronomical sites and sun-aligned artefacts; • customise your iPhone or iPad screen with widgets. App features: • Augmented reality (AR); • interactive plot and map; • sunrise and sunset times; • Save locations for bookmark and to configure widgets; • summer solstice and winter solstice; • time zones and daylight saving time; • easy sharing: save and send the sun path plot and the map, along with essential information (sunrise, sunset, and link to map); • location lookup by coordinates, reverse geocoding, or name; • curated list of sun-aligned artefacts, archaeoastronomical sites; • multiple windows in iPadOS: view different sites at the same time. Interactive plot and map: • swipe up and down on the plot to change the time of day, or the date; • swipe on the map to change the coordinates; • tap on the date to change mode (date or time); • long press on date to input specific date or choose time zone. Note: Never look at the sun without proper protection.

Hidden in plain sight. Phasm turns ordinary photos into secret messengers. Your photo looks exactly the same — but it carries encrypted messages and files that only someone with the right passphrase can reveal. TWO MODES FOR TWO NEEDS • Ghost Mode — Maximum stealth. Advanced adaptive algorithms make hidden data virtually undetectable, even by statistical analysis tools. Deep Cover auto-activates for non-JPEG photos with ~43% more capacity. Supports file attachments alongside your message. • Armor Mode — Maximum durability. Your hidden message survives recompression, re-encoding, and mild cropping. Fortress sub-mode auto-activates for short messages and handles aggressive compression from popular messaging apps. SERIOUS ENCRYPTION • AES-256-GCM-SIV authenticated encryption — always on, not optional. • Argon2id key derivation — resistant to brute-force and GPU attacks. • Post-quantum safe — 256-bit symmetric keys remain secure against quantum computers. • No backdoors. No key escrow. You hold the only key. PRIVACY BY DESIGN • All processing happens on your device. Nothing is uploaded. • No account. No sign-up. No tracking. No ads. • Open-source Rust cryptographic engine — auditable by anyone. • Built for journalists, researchers, activists, curious tinkerers — or just for fun. ONE PHOTO. MULTIPLE SECRETS. Shadow Messages let you hide several independent messages in a single photo — each locked with its own passphrase. Send the same picture to five friends; each one discovers a different message using their name as the key. Nobody knows the others exist. Under pressure to reveal your passphrase? Hand over the primary one. Your shadow messages stay invisible — no header, no marker, no proof they were ever there. MAGIC WAND — ONE TAP TO OPTIMIZE Tap the wand and your photo is silently tuned for better steganographic embedding. Imperceptible texture is added to smooth regions like skies, bokeh, and flat backgrounds — boosting capacity by 10–35% with no visible change. The photo looks identical. The math works better. SHARE YOUR WAY • Share via AirDrop, Messages, email, or any app that handles images. • phasm.link — generate a short link so recipients can decode instantly in the browser or via App Clip. No install needed. • For guaranteed delivery through messaging apps, use "send as file." BUILT FOR iPHONE AND iPAD • Native app optimized for iPhone and iPad. • Supports JPEG, PNG, GIF, WebP, and HEIC — auto-converted for embedding. • Real-time decode progress with integrity scoring. • 38 languages supported. HONEST ABOUT LIMITATIONS • Platforms that resize or re-encode photos may destroy hidden data. Use direct sharing or "send as file." • Capacity depends on image resolution — larger photos carry more data. • Steganography hides the existence of a message. Encryption protects its content. Phasm gives you both.
