Eclipse Timer app analytics for August 23

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.
