Suntime connects you to the cycles of the Sun, Moon, and planets. Navigate through time and identify celestial patterns with a swipe. Get accurate, location-specific information about solar and lunar events at-a-glance.

“Awesome” — “Visually understand the cycles in our planetary system” — “Feel connected to the universe”

- Zoom the timeline in or out to see astronomical movements at different scales
- Jot down notes and reminders directly on the timeline
- Watch the Sun, Moon, and planets rise and set
- Home screen widgets: upcoming events and planisphere
- Customize alerts for 25 solar and lunar events, including:
> Sunrise, solar noon, sunset, solar midnight
> Moonrise, lunar noon, moonset
> Moon phases: full moon, new moon, first quarter, and last quarter
> Twilights: civil, nautical, and astronomical dusk and dawn
> Morning and evening golden hour

“Beautiful and an absolute delight to use” — “Easy to follow interface and alarms” — “Pretty damn cool”

Suntime works in landscape and portrait mode on iPad. Use your current location, or select one manually. The app is lightweight and works offline: all astronomical calculations are done on your device. It uses Background App Refresh to schedule alarms.

“Wonderful visualization of Solar + Lunar cycles in a very intuitive format. Animations are superb”

There’s more to explore inside: including a glossary and tooltips with contextual information like the position, angle, illumination, and magnitude of the Moon, the visibility of eclipses, and the length of twilight.

We are ad-free and user-supported: Suntime doesn’t track you or profit from your information. Thanks to all our users who have given us feedback and continue to help make this app better!

A beautiful App

Update; This is not a one time purchase. I am not seeing a receipt or subscription to cancel. Being charged multiple times. Be aware!

Old post! Very easy to use and hard to put down. I found this app by chance while looking for an Almanac. A nice surprise in design and usefulness. I love the in-app search and notification features. The tutorial says if you click around in the app, you will find so many useful features and I agree. I don’t usually review apps unless they are extraordinary and this one is. Five stars well deserved!

Really cool app

Got an invite for the beta, so I’ve been using the app for a couple of months now. The app has a really cool, intuitive visualization for sun and moon phase, which is a lot of fun to play around with. (Zoom all the way in and out, it’s pretty neat!) My favorite thing right about the app is the customizable chimes to alert when certain astronomical events occur. It’s actually really great to get an alarm when the moon is at its peak so I can take a break, go outside, and enjoy the view.

Developer Response ,

It’s great (for me)

If you want something to keep track of the planets or remind you of the lunar moon sum like that get this app its cool in my experience. I like when I can go out look in my telescope and see saturns rings well you can keep track of where all the planets are you can also use it as a fidget on your devise. I think if you like keeping track of the planets time and sunrise/sunset get this app!
