Albedo vs UberSDR

• An interactive map and real-time trajectories Track iconic satellites such as the ISS, Tiangong, Hubble as they move across the sky. The interactive map displays their real-time positions and ground track, helping you spot visible passes from your location with ease. Plus, new satellites are added to the app each time a new visible satellite is launched into orbit! • Anticipate passes with precision Plan your observations in advance by checking upcoming passes up to 7 days ahead. You’ll get all the essential information, including brightness magnitude, entry/exit from Earth’s shadow, weather conditions, cloud cover, and lunar phase. The app calculates your chances of observation, so you know when it’s the best time to look up. A built-in compass helps you visualize the satellite’s trajectory in the sky, making it even easier to know where to look. • Personalized notifications based on observation conditions Never miss a moment in the sky with customizable alerts. You can choose your favorite satellites, set a notification pre-alert period (from 5 to 30 minutes), and receive notifications only when the conditions are right for viewing. • Designed for space lovers, photographers, and casual observers This app is ideal for astronomy enthusiasts, photographers, and anyone who enjoys looking at the sky. Its clean, user-friendly interface makes it simple to use for both beginners and seasoned sky watchers, while providing all the detailed data needed for a perfect stargazing experience.

UberSDR makes your iPhone or iPad the front end of a real radio receiver, anywhere in the world. Pick one from the public directory — dozens of them, run by enthusiasts from Scotland to Brazil — or find a receiver on your own network. No account, no sign-up, no hardware: you are listening within seconds. Tune by spinning the frequency dial, dragging the waterfall, or tapping a marker. Signals arrive on a live spectrum and waterfall you can zoom and hold. Choose LSB, USB, AM, SAM, NFM, FM or CW, set the passband by hand, and pull a weak station out of the noise with noise reduction, a notch filter and squelch. Shortwave broadcasters, the amateur bands, aviation, marine, time signals and stranger things besides. A band plan and live DX cluster spots say what you are hearing; bookmarks take you back to it. Audio carries on when you lock the screen or move to another app, with the usual controls on the lock screen. Everything stays on your device. Nothing is collected, and there is nothing to sign in to.
