Hi, Maricel. This is a great question for me…I’m an sky/weather app collector! Hands down, my go to is Dark Skies. This is both a great web site an a excellent app. I’ve had found it very accurate overall and I love the focus on sky conditions. I also use it as a complication on my Apple Watch, so I’m all in on it. I also like Weather Underground: https://itunes.apple.com/us/app/weatherunderground/id486154808?mt=8
My Radar: https://itunes.apple.com/us/app/myradar-noaa-weather-radar/id322439990?mt=8 Weather Bug: https://itunes.apple.com/us/app/weatherbug-local-weather-radar/id281940292?mt=8 On the high end for sunrise/sunset guides you’ll find the professional app Helios to be totally complete. Perfect for long term or remote scouting it lets you know exactly where and when the sun will rise anywhere in the world. It has many sub programs including moon predictions. Most importantly you’ll find a built in compass and inclinometer so will be able to exactly pinpoint every aspect. It’s not inexpensive at $29.99 but worth every penny. Another sunrise/sunset guide is The Photographers Ephemeris. Not quite as all inclusive but very useful and full featured. Cost’s will vary with in app purchases, starts around $5.
