Synaura
Biorhythm Radar
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Synaura is a human-compatibility radar. Put your phone down, let it sense the energies around you — Synaura finds people whose biorhythm aligns with yours and reveals them discreetly, with no location sharing and no social profile.
◆ A RADAR, NOT A SOCIAL NETWORK ◆
• Silent Bluetooth LE and UWB (U1 / U2 chip) detection
• Biorhythm compatibility computed from two birth dates
• Ephemeral encrypted chat with the person you cross, if they accept
• No account to create, no public profile, no stored geolocation
◆ BIORHYTHMS, NOT HOROSCOPES ◆
Synaura's engine is built on the mathematical biorhythm model: three sine-wave cycles (physical 23 days, emotional 28 days, intellectual 33 days), formalized in the 1920s. No daily horoscope, no prophetic claims — just the mathematical wave of your energy, compared to others'.
◆ 50+ INTROSPECTION TOOLS ◆
• Aura Card — generative portrait of your energy signature
• Moments — photo archive correlated with your peak days
• Dreamweaver — AI dream journal (on-device)
• Birthday Film — your year, cinematic
• Health correlation — Apple Health (HealthKit) ties sleep, steps, heart rate to mood
• Daily rituals, Echo Chamber, Breath Mirror, Chronosonic, Silent Compass, Time Capsule, Celestial Pulse, Palm reading, Daily Oracle, Astral Crystal, Cosmic Year, Living Theme...
◆ DATA PROTECTION ◆
Synaura processes everything on your device. No biometric data, no photos, no location leaves the device. The AI (Dreamweaver, Oracle) runs via on-device Apple Intelligence by default. A cloud model can be enabled — never imposed.
