Greetings, Tau'ri! This application simulates the Stargate Dial Home Device (DHD). Instead of establishing wormholes to distant planets, this DHD connects you to your contacts via the primitive Tau'ri communication network - also known as "phone calls." HOW IT WORKS Dial a 7-glyph address on the DHD interface. Each glyph you tap locks a chevron, accompanied by authentic sound effects and haptic feedback. Once all seven chevrons are locked, press the central activation dome to engage. If the address matches a saved contact, the call connects. If the address is unknown, you can map it to a contact from your address book for future dialing. FEATURES - Dial Home Device interface with concentric glyph rings and a central activation dome - 7-chevron locking sequence with sound effects and haptic feedback - Cartouche address book: save, view, and manage your glyph-to-contact mappings - Swipe to re-dial saved addresses with automated glyph entry - Swipe to delete entries you no longer need Whether you're a fan of the Stargate franchise or just want a unique way to call your friends, the Dial Home Device brings a bit of sci-fi fun to your day.
