Nice app but can’t go very far in future

I really like the design of this app and it works really well. But at the moment I can only view eclipses through 2022. That’s really not that far in the future and hope this is only because it’s a pretty new app. Hope they make eclipses further in the future able to be viewed soon

Thank you very much for the review! We will add more eclipses in the future updates.

Very Nice App - RECOMMENDED!

I bought this brand new app for the January 20, 2019 total lunar eclipse and it worked flawlessly. I was quite pleased at how it showed the terrestrial path of the eclipse, how complete or partial a view you would have from your location, and the times (and a time lapse video) for the beginning and end of each phase of the eclipse. I REALLY liked being able to turn on the specific alarms/notifications that I wanted (just “click” the red alarm clock symbol in the event list for the ones you want to be notified for). I’ve already gotten my 99 cents’ worth!

That said, there were a couple things I would like to see in the next update. Number one is the option to choose a 12 hour clock. I understand the scientific reasons for the 24 hour clock but conventional timing for both the time lapse video and live clocks would have made the app much easier to use. Also, I really like that you can browse past and future eclipses (with a handy eye icon that tells you which will be visible from your location), but graying out past eclipses would have made it easier to see “when” I was as I browsed.

Overall this app is more than worth the 99 cents, and I hope a few minor tweaks will make it even better. I recommend it.

Not reliable at all.

I bought this for today’s eclipse and having enjoyed this developer’s other apps, I expected a working app. Unfortunately, it let me down. At the time of purchase, it seemed to work with a good timeline of the eclipse for my location. Yet when we went out to see the eclipse, it kept telling me that it was not viewable from my location even after manually selecting my city, closing and restarting the app, and even restarting my phone. In the end I just had to go to sky and telescope on my browser to get my timeline instead. Utterly worthless app. I can not recommend it at thus time.
