Eclipseando: Eclipse 2026

Your town, not the headlines. Exactly what the eclipse of 12 August 2026 does from where you stand: the times, how much of the Sun goes, whether it goes dark. Offline.

That evening, with the Sun low, the Moon's shadow crosses mainland Spain and the Balearics. If you are heading south, half of Spain is outside the path. 4,065 of its 8,131 towns get a partial, with a median of 99.3% of the Sun covered. And 99.3% is not "almost totality". It is a different event.

BOOKED A CITY? CHECK IT FIRST

Madrid 99.9%. Barcelona 99.8%. Seville and Málaga 94.7%. In those cities it does not go dark, the corona never appears, and the filter never comes off. The gap between 99.9% and 100% is not 0.1%: it is seeing it or not seeing it. It tells you what you will really see instead of saying "you are outside" and going quiet.

SHOULD I MOVE? HOW FAR?

Destinations are ranked by what you gain, not by how near. The closest town with totality usually hands you 12 seconds, which is nothing. From Madrid, El Molar is 28 km away with 61. From Seville, the nearest 60 seconds is 422 km away: the app tells you not to go.

WHAT YOU GET, IN THREE SECONDS

· Whether it goes dark where you are. No hedging.

· First contact, maximum and end, in local time.

· How many seconds totality lasts, if there is any.

· How much of the Sun is covered, and how high it will be.

THE DATA TRAVELS WITH YOU

The times, the map and all 9,255 towns across nine countries — Spain, Portugal, France, the United Kingdom, Ireland, Iceland, Italy, Germany and Morocco — are worked out inside the phone. On 12 August, on a crowded hillside with the network jammed, that is the difference between having the time and not having it.

WHERE TO LOOK

This eclipse happens with the Sun very low: a median of 7.1° above the horizon, and below 10° in 7,638 of Spain's 8,131 towns. At that height a three-storey building 80 metres away hides the Sun completely. The app gives you that height for your town, so you can check your horizon with your own eyes. And something almost nobody mentions: in 6,494 towns the eclipse never ends, because the Sun sets first.

GLASSES AND SAFETY

Never look at the Sun without a certified filter. The prompt to take the filter off appears only where there is totality and it lasts long enough. Where there is none, the app says what has to be said: the filter stays on.

THE CAMERA

Photos come out with your town, the exact time and the percentage covered stamped on the image. Video records clean: re-encoding a whole clip on a hot phone costs CPU minutes you cannot spare. To share it, the video card — one frame, stamped. An automatic shutter covers the minutes that matter, so you are not staring at a screen when you should be looking up. And the solar filter warning stays in front, always.

WHAT USES THE INTERNET AND WHAT DOES NOT

The eclipse does not: nothing above needs a connection. One thing uses it, and only if you open it: the cloud report, where people say in one tap what is over their town, and you see what the ones nearby report. Nothing else leaves the phone. Your location, if you give it, stays inside and is never sent: only the town name is kept, and you can type it in by hand.

FREE, AND PAID

Free: the time, the duration, the percentage, whether it is total or partial here, the safety guidance, the search, the camera and its stamp, the widgets. Separately, a Pro: one payment, no subscription, with three develop presets made for eclipse light, your totality photos laid out in a single strip, and the stamp removed.

FINDING YOUR TOWN

With its province beside it, because 17 names are repeated. And under the names people use: type Gerona, Ibiza or San Sebastián and you get Girona, Eivissa and Donostia.
