Don't buy this app!

I am a planetarium director and professional astronomy educator. This app is horrible.

Two glaring issues: You _have_ to enter a city - the app won't make calculations based on your current location, even though there's a button that indicates you can find your location automatically. If you try to "Use Current Location", the app displays blank spaces for eclipse start and end times.

What if you're in Reno, Nevada on May 20th 2012 for the Annular Eclipse? Good luck! The database doesn't know where Reno is (how can you not list the second most populated area of Nevada?), and it won't use your phone to locate itself. You'll have to manually enter longitude and latitude. Lame.

It gets worse! There's a total solar eclipse on August 21, 2017, passing straight through Jackson, Wyoming. Does this app know where Jackson, Wyoming is? No. But no matter, this app doesn't even acknowledge that an eclipse of any kind happens on that date! This is inexcusable.

Also, it makes no adjustment for daylight saving time, which for most of us in the US, means your summertime calculations will all be off by an hour.

I wasted a buck and a half hour of my time discovering how awful this app is.

Don't repeat my mistake.

Daylight savings time FAIL

Argh! I created a chart of eclipse times for people in different places using this app, and today I find it's off by an hour for California -- and probably everywhere -- because it's ignoring Daylight Savings Time.

And it's too late for me to warn everybody! I just had to take my webpage down because I'm already at the viewing site and can't edit from my smartphone.

What a waste of a buck. I am beyond annoyed.

Useful!
