Eclipse Timer vs Albedo

Eclipse Timer computes precise contact times for solar eclipses at any location you choose — down to the second. Pick an eclipse from a catalog spanning 1900 to 2100, drop a pin on the map or use your GPS, and instantly see when each phase of the eclipse begins and ends at your exact location. FEATURES • Browse 200+ solar eclipses from 1900 to 2100 — total, annular, partial, and hybrid — with search and filtering by year, date, type, or catalog ID. • Tap the map, drag a pin, or use GPS to set your observer location. The engine computes results for your precise coordinates. • View all five contact times (C1, C2, Greatest Eclipse, C3, C4) in both UTC and your local time zone. See eclipse type, magnitude, and duration of totality or annularity at your chosen spot. • Live countdown timer shows days, hours, minutes, and seconds until the next eclipse event for the selected eclipse. • Set notification reminders for eclipse contacts — one hour before, ten minutes before, or at the moment of each event. Choose between system sounds, vibration, or spoken voice (TTS) alerts. • Interactive map overlays show the eclipse's visible path and central line so you can see where totality or annularity occurs. • NASA preview animations let you visualize each eclipse before it happens. • Save favorite locations for quick access across different eclipses. HOW IT WORKS Eclipse Timer uses the classical Besselian elements method — the same mathematical framework used by professional astronomers — to compute local eclipse circumstances. The engine evaluates polynomial shadow geometry at your observer coordinates to determine exactly when the moon's penumbral and umbral shadows reach your location. All computation happens on your device. Your location is never sent to any server. PRIVACY Eclipse Timer requests location access only when you choose to use GPS. Your coordinates stay on your device and are used solely to compute eclipse times. The app contains no ads, no analytics, no tracking, and no user accounts. See our full privacy policy for details. Whether you're planning a trip to see totality, checking if a partial eclipse will be visible from your backyard, or exploring historical eclipses — Eclipse Timer gives you the precise timing data you need.

Whether you're timing a golden hour shoot, tracking moonrise for a night hike, or simply wondering what the moon looks like tonight, Albedo puts precise astronomical data inside an interface designed to feel like cinema. REAL NASA MOON, FRAME BY FRAME 720 high-resolution lunar images map every hour of the 29.5-day synodic cycle. Scrub through time with a precision slider and watch the moon wax and wane in front of you. Each frame is a real photograph — not a rendering. GOLDEN HOUR & BLUE HOUR TRACKER Know exactly when the light is perfect. Albedo calculates morning and evening golden hour and blue hour windows for your location, displayed on a beautiful 24-hour light chart. Plan your next shoot down to the minute. MOON CALENDAR Browse lunar phases across any month from 2000 to 2100. Each day shows a thumbnail of the moon's appearance, making it easy to plan around full moons, new moons, and everything in between. MOON JOURNAL Attach notes and photos to any date on the calendar. Record observations, mark shooting conditions, or keep a lunar diary. Your entries are stored securely on-device with SwiftData. AR MOON FINDER Point your camera at the sky and find the moon. Albedo places an accurate 3D moon at the real lunar position using ARKit, with a guide arrow when the moon is off-screen. INTERACTIVE 3D MOON Explore a textured 3D lunar globe you can rotate freely. Examine the surface up close, from the Sea of Tranquility to the Tycho crater. MOONRISE, MOONSET & DISTANCE Precise moonrise and moonset times for your location, plus real-time lunar distance. All calculations adapt as you scrub through time. SMART NOTIFICATIONS Get notified before full moons, new moons, and evening golden hours so you never miss a moment. Customizable alerts delivered at the right time. LOCATION-AWARE Albedo uses your GPS for accurate local calculations, or let you search and set any location manually. All solar and lunar times adjust instantly. DESIGNED FOR DARK A pure black interface with glassmorphism accents and cinematic serif typography. Albedo is built for night use — easy on the eyes, beautiful in the dark. WORKS EVERYWHERE Available on iPhone, iPad, Mac, and Apple Vision Pro. Your moon, on every screen.
