About this app

EclipseDroid is the ultimate companion for each engaged solar eclipse observer and all people, who are interested in solar eclipses. The app calculates exact data for any solar eclipse at any location. Relax and watch the eclipse and not your cameras, EclipseDroid will work for you!

New in Version 8: Search eclipses for your location, Portuguese language support.

Version 5 includes an EFlight mode for eclipse observation from an aircraft. Now all timing tasks will run in a service which prevent from being terminated in background.

EclipseDroid is especially designed to support engaged solar eclipse observers in their observations. It will show timetables and countdowns for the contact times, make acoustic announcements of the contacts or other user defined events. It will launch other apps, show text announcements and trigger internal or external cameras connected by USB (USB host capability and USB OTG cable required) or optical cable. All these events can be defined and customized in a script by the user. The timings of the events depend on the contact times which are calculated with high precision from the actual device's position or a custom location. For using USB functionality please set "USB Debugging" to On in Android Settings, Developer Settings.

To prepare your eclipse observation, select a desired location from the map, from a list or input free coordinates. To rehearse and check your observation program, simply run EclipseDroid in eclipse simulation mode. When selecting and checking your observation site, avoid unpleasant surprises like buildings or trees blocking your eclipse view! Just call the AR screen of EclipseDroid to see an overlay of the Sun's position at eclipse time with an actual camera image (only availabe in full version).

EclipseDroid has several screens and layouts to show the precise contact times for your location. These are the beginning and end of the eclipse (C1 and C4), the beginning and end of the total or annual phase (C2 and C3), the time of mid eclipse and the current percentage of coverage of the solar disk. You have the choice of two layouts: a smart layout showing the local circumstances and an animation of the eclipse in a condensed form or the classic layout with countdowns for all contacts, an events list with the next upcoming events and the actual eclipse view, if the eclipse is running.

In the 'eclipse details' screen you get full information about the local circumstances of the eclipse. Pressing 'Menu' will add the eclipse to your favorite personal calendar.

Rubbish. Doesn't work offline. Comes up with wrong times. Online and restart is fine. But offline is not! Even the date is wrong!

EclipseDroid and Eclipse2013 provide the same time, as long as you set in EclipseDroid the same time zone. The times are identical to the times on the NASA-Website, if DeltaT is adjusted by one second. Permission "Your Account - Read Google service configuration" is needed for the Google maps module

This is a great app! I had several apps installed yesterday and this displayed the best and most complete information with no advertising getting in the way. I'm buying the pro version as a thank you, and I hope you're around in 2024!
