“Perfect app. I rarely take the time to review apps and rarely like them. This does exactly what it is supposed to, isn't bloated, and has any feature you would need for a sunrise/sunset alarm and timetable. Super intuitive and user-friendly interface. Widget is great. I've used it failthfully for 3 years now and couldn't be happier.”
“Simple, easy to use, accurate! I wanted an app to easily check daylight hours for hiking, and also to set up sun-based alarms. I love the amount of customization available, and the layout is clear and easy to understand. This app is great, couldn't recommend it more.”
“The new maps feature is chef’s kiss. This app has always been super simple and useful for me, but the new maps feature has added so much. I’ve been using it when searching for a new house to figure out where the sun will be during the day. As an avid gardener, this is super useful and exciting when looking at potential houses.. not to mention the reasonable one time purchase prices 🙌🏼”
