How much radiation did your last flight expose you to? Find out... FlightDose is a scientific aviation tool for estimating exposure to cosmic radiation during flight, based on established aerospace radiation modeling principles. At its core, FlightDose leverages methodologies derived from CARI-7, a widely recognized aviation radiation dose model developed for analyzing radiation exposure at altitude. By combining route geometry with altitude, latitude, geomagnetic shielding, and solar conditions, FlightDose provides informed estimates of in-flight radiation dose in a clear, modern interface. Cosmic radiation increases rapidly at cruising altitudes and varies significantly by latitude and flight path. FlightDose makes this invisible environmental factor understandable using real aviation physics and data-driven calculations. What FlightDose does • Estimates in-flight radiation dose using CARI-7–based modeling concepts • Accounts for altitude, geographic position, and Earth’s magnetic field • Supports route-based and flight-based dose estimation • Presents results clearly without unnecessary complexity Who it’s for • Pilots and aircrew • Frequent flyers • Aviation professionals and students • Engineers, researchers, and science-focused travelers • Anyone curious about estimating radiation dose during flights Important information FlightDose is provided for informational and educational purposes only. It is not endorsed by the FAA and does not provide medical advice, diagnosis, or risk assessment. All dose values are estimates and should not be used for clinical, regulatory, or occupational decision-making.

Factoro Authenticator keeps your two-factor authentication (2FA) codes safe, simple, and always with you — from Factoro. - Add any account that uses standard authenticator apps (Google, GitHub, AWS, Microsoft, your bank, and more) by scanning its QR code or entering the key by hand. Factoro - Authenticator generates the time-based codes you need to sign in, with a clear countdown and one tap to copy. Never lose your codes again. Turn on end-to-end encrypted iCloud backup and your accounts come back automatically when you set up a new iPhone — no passwords to remember, nothing to export. Your codes are encrypted on your device before they ever leave it, so neither Apple nor Factoro can read them. Private by design - No account and no sign-up — it just works. - No analytics, no tracking, no third-party SDKs. - No Factoro servers: the only place your data goes is your own iCloud. Built for trust - Works with any service that supports standard 2FA (TOTP) — not just Factoro. - Optional Face ID / Touch ID lock, with a privacy screen when you switch apps. - Copied codes clear from the clipboard automatically. - Full support for English and Spanish, VoiceOver, and Dynamic Type. Factoro Authenticator replaces "install another authenticator" with a polished, first-party app you can trust with your most important logins.
