Satrelle vs Control Tiempos Eclipse

On August 12, 2026, the moon's shadow crosses Spain at more than two thousand kilometers per hour. Satrelle tells you exactly when it reaches the spot where you're standing, to the second, computed on your phone, no signal required. FREE, A COMPLETE OBSERVER'S TOOL • Contact times C1-C4 for your exact position, from NASA Besselian elements, computed entirely on-device • Totality duration, sun altitude, and a live countdown • Set your site by GPS, on the map, or by typing coordinates • The 2026 and 2027 eclipses, plus future events • Works fully offline, in a field, on a mountain, anywhere THE PHOTOGRAPHER'S KIT, ONE PURCHASE, YOURS FOREVER Everything you use with a camera in your hands: • Exposure toolkit, Espenak tables computed for your aperture, ISO, and filter, with live atmospheric extinction for your sun altitude • Corona-pass fit, how many full bracket ladders your totality holds • Eclipse-day mode, timed voice callouts, camera-filter warnings, and T-minus haptics through all four contacts • Live Activity, the countdown on your lock screen and Dynamic Island • Rehearsal mode, practice your totality before you spend it • Site comparison, save candidate sites and compare their durations • Clock verification against NTP, contact times ride on your clock • Manual contact times from any limb-corrected site prediction The Kit is a single one-time purchase. It includes the August 2027 eclipse and every eclipse after it, it's shareable with your family, and every feature works with no connection at all. SAFETY Never look at the sun without ISO 12312-2 eclipse glasses. The only exception is totality itself, between second and third contact, and Satrelle tells you exactly when that is.

Control Tiempos Eclipse is a spoken director for solar eclipse photographers. During an eclipse, every second counts and every glance at a screen is a photo you lose. The app announces each moment out loud — filter off, bracketing, diamond ring, totality, filter back on — so you never need to look at your phone. HOW IT WORKS Choose an eclipse, set your observing position (GPS or manual coordinates), and the app computes your exact local contact times — C1, C2, maximum, C3, C4 — using an embedded astronomical engine. Then build your photographic program: a sequence of timed voice cues anchored to those contacts. When the day comes, press start and listen. The app speaks; you shoot. ENTIRELY OFFLINE Everything runs on your device. The eclipse dataset (2025–2035) is built in, the timing engine needs no network, and the voice announcements use the system's own speech synthesizer. No signal on a remote hilltop? Perfect — neither the app nor you need it. REHEARSE BEFORE THE DAY A rehearsal mode lets you run your full program in accelerated or real time, so you can practice your camera movements and refine your script days before the eclipse. On eclipse day, nothing is improvised. DESIGNED FOR THE FIELD - Precise timing engine with sub-second announcement accuracy - Programs built around the real contact times of your exact position - Clear execution screen with the next cue always visible - Works with the screen locked in your pocket - No account, no ads, no data collection — see our privacy policy Built by a photographer, for photographers, with the August 12, 2026 total eclipse over Spain as its first mission.
