About

Control Tiempos Eclipse

Read full description

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. In English, Spanish and Catalan.

Other apps tell you when the sun rises. This one tells you whether you'll see it. Astrian Light knows the real terrain where you're going to shoot —the ridge, the building, the hill in front of you— and tells you when the sun actually clears it. Not when it rises on a flat horizon that doesn't exist. WHAT IT ANSWERS · When the good light starts at your spot, and when the terrain takes it away. · Where the sun rises and sets, right on the map. · How many hours of dark sky the Moon leaves you tonight, measured against your horizon. · When the Milky Way core rises, and which is the next moonless night. · What the eclipse will look like from where you'll be, when, and how long totality lasts. ECLIPSES, ALWAYS FREE On August 2, 2027, a total solar eclipse crosses Spain. The map of every eclipse, how much of the sun is covered from any point, the timeline to the second, and whether your horizon lets you see it. No subscription, now or ever. YOUR GEAR, BUILT IN Over 600 lenses and 230 cameras in the catalog; if yours isn't there, type it in. From then on, the ten calculators speak your gear: exposure without star trails, hyperfocal, depth of field, field of view, filters, timelapse. And "Your frame" shows how the shot will look in your camera before you go. THE SKY, RIGHT NOW Point your iPhone at the sky and augmented reality tells you what you're looking at: planets, constellations, the space station, deep sky. PLAN BEFORE YOU LEAVE Compare several destinations and several nights at once. Save plans with their place, their date and the gear you're taking. And bring the verdict with you: the calculations work without signal. YOUR WAY Buttons with symbol and name, or name only. Light and dark themes. Times in your iPhone's format. In English, Spanish and Portuguese, on iPhone and iPad. WHAT IT WON'T DO It doesn't make data up. When it doesn't know, it says so: if there's no measured terrain for your point, it tells you the figure is for a flat horizon. If the forecast doesn't reach, it won't invent one. SUBSCRIPTION Astrian Light is free for eclipses and for today's sky where you are. Everything else —any date, any place, the whole sky, all your gear— needs the yearly subscription. It renews until you cancel, and you cancel from your Apple account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
