About

Control Tiempos Eclipse

Features
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.
