What time is sunset today? Or sunrise tomorrow? When is the "magic hour" next March 20 in Paris? With Sol, you can check times and get reminders of solar events, at home or while traveling! Great for everyone looking to plan activities based on sunlight. Use it to remind you to walk the dog before dark, get up with the sun, or find golden hour time for that perfect photo. Sol: Sun Clock is the Swiss-army knife of sunlight tools with a design inspired by the simplicity of the sundial. Use it to plan your day, guide natural sleep cycles, get the best light for outdoor photography, make sure animals or kids are safe inside before dark, or to map out the best times to go running or fishing. * Be in tune: Sol will tell you when the golden hour is, how much sunlight you have left in the day or what time the next sunrise occurs. * Look to the future, travel around the world: Sol lets you find sunlight information for any date, anywhere on earth. * Find solar midnight and solar noon, and all three twilight (dawn and dusk) periods: astronomical twilight, nautical twilight, and civil twilight. Keep tabs on the next solstice and equinox. * Reminders and Alarms: Use Sol as a natural alarm clock that you can set to any event (like sunset, golden hour or solar noon), and the alarm or reminder time will adjust gradually as the days change with the seasons. * Automatic Location: Sol not only calculates the amount of daylight and sunrise and sunset times, but does so for any location in the world (both Northern and Southern hemispheres) by using your device's GPS... no network connection required. * Other locations: Optionally, use the built-in map to choose any location in the world by moving the pin, or search using the name of any city. * Optional location-aware alarms. Sol knows when you change with your location; and as you travel it will adjust any alarms you set relative to sunrise and sunset times. Create alarms for multiple locations around the world. * Detailed almanac information: Useful information about the day's length, sun's azimuth and elevation, equinoxes and solstices, and a friendly glossary that explains all the terms. Note: Continued use of GPS running in the background can dramatically decrease battery life. However, GPS runs in the background ONLY if you have set location-aware alarms.
Version History Due to a bug in Apple's iOS 18, in some locations the month in the Date Picker dialog could be a month off. Version 5.1.5 circumvents the bug for iOS 18 users until it can be properly fixed by Apple. We also fixed some external links that were not opening from within the app, and linked to our new social media account on Bluesky. 5.1.5 02/05/2025 1) Fix to popup window toolbar appearance issues switching between Dark Mode and Standard (Light) Mode. 2) iPad version now has black main toolbar like iPhone. 3) Fix to Tutorial on iPad. 4) Fix to bug where notification sometimes showed empty time string. 5.1.4 06/20/2023 Minor improvements. 5.1.3 05/16/2023 Despite our best efforts in 5.1.1, users who had upgraded to iOS15 were still occasionally having their preferences zapped. We have made substantial additions to the code to try to protect users against any data loss. The app now keeps multiple backups of its settings file, and in addition, users may choose to manually back up their settings. (If you have had issues in previous versions, we recommend installing a fresh copy of the app by deleting your previous version first.) 5.1.2 11/17/2021 Fixed the disappearing settings (including custom alarms) bug that was still affecting some users, as well as the slightly clipped earth graphic on some iPhones. 5.1.1 10/22/2021 Supports iOS15; bugfixes (including map pin drop), and improved tutorial. 5.1.0 09/29/2021 Fix to orientation bug in some iPhones. 5.0.5 06/23/2020 Dark mode implemented. 5.0.4 03/05/2020 Minor bug fixes. 5.0.3 02/19/2020 Removed Google Analytics and fixed some minor bugs. 5.0.2 02/17/2020 Fixed tappable date area on iPhone X series. 5.0.1 01/24/2019 User interface is now adapted for newer iPhones' display sizes and bevels at their native resolution. Code is now updated for newer iOS features and requirements. Requires iOS 9.3 or later. 5.0.0 01/21/2019 The wheel now represents a full solar day for set location, which is not necessarily exactly 24.0 hours. The date bar now shows and sets the solar day for the location, not the clock time, which is shown separately and is independent from the solar day. The Almanac now shows solar day length and sun zenith at solar noon. Days with daylight saving time (DST) transitions will show the time change on the wheel. All known bugs were fixed, including those relating to using the forward and back arrows, daylight savings/summer time issues, and incorrect alarm times and repeat days. iPhone only: The info bar (under the date) now animates new information by default and remembers its state (double-tap to toggle). More information about this release can be read here: http://www.juggleware.com/blog/?p=776 4.0.0 04/21/2017 Fixed bug where the first 3 alarms weren't sounding in "persistent" mode. 3.2.2 09/25/2016 Hotfix for 3.2 that reads older (3.1.0 and earlier) alarm settings correctly. 3.2.1 07/29/2016 New feature: • Timezone "Map mode" option for manual locations: automatically update the time zone displayed to whatever location you pick on the map. (Tap on the time zone to enter time zone picker; as always, tap on the green earth to pick a new location). Accuracy, speed, usability and bug fixes: • Completely reworked date/time code; should fix the occasional bugs that some users were reporting. • Improved speed/responsiveness. • Removed Badges as a required Notification type; this was causing unnecessary alerts about setting Notifications for people who didn't have or want badges set. • Updated icons etc for latest device models. • On colored pie wheel: for improved interactivity, skip drawing slices for periods that are less than 2.5 minutes long; for better visualization, only draw text labels for periods that are more than 10 minutes long. • No longer calculating solar midnight by subtracting or adding 12 hours from solar noon... this could be off by several seconds. Now using traditional Roman method of finding the midpoint between sunset and next day's sunrise. • Renamed "Night" period to "Full Darkness". • Fixed error in Glossary about months. 3.2.0 07/28/2016 Fixes an iOS 8 issue on iPhone with the date selector on the main screen, and updates notifications and location updates to be compatible with iOS 8's new privacy permissions. 3.1.0 10/16/2014 Fix to crash on iPhone 5s after tapping the date. 3.0.4 04/05/2014 Fix to incorrect azimuth when in DST mode. 3.0.3 03/24/2014 Bug fixes: * Fixed crash that could occur when closing the main Date Picker just as the spinning dial was about to stop. * Fixed DST issue with solar azimuth display. * Tutorial dialog should no longer come up twice. New Features: * [iPhone] Now remembers which of the swipable infobars (below date) you were looking at when you re-open the app. * [iPhone] Double tapping the swipable infobars now toggles auto-scrolling. (Note: Off by default. Manually swiping also turns this behavior off. Area flashes red or green on double-tap to show new state.) Minor Tweaks: * Shows abbreviated city names where necessary. * Map Picker shows smoother updating of location pin annotation. * Tutorial delay time changed from 5 minutes to 15 minutes. * Limited date entry from 1950 to 2050 so that it’s compliant with library that gets solar elevation. * "Rate this app" dialog appears later the first time, and much later if you press "later." * No longer resets user-has-seen-tutorial state on new version update. 3.0.2 01/09/2014 Fixes bug to some longer ("persistent") alarms not sounding in version 3.0. 3.0.1 12/06/2013 For version 3.0 we have rebuilt Sol: Sun Clock's user interface exclusively for iOS 7. For example, it now takes advantage of Motion Control (the stars now appear to be behind the earth and the clouds in front). We've taken advantage of other iOS 7 UI features as well such as transparent UI elements. Alarms now have 30-second versions when you set them to "persistent" mode. We added a new alarm sound as well called "Wake Up Gently" especially designed to rouse you at sunrise. The chart now shows info for Sunset, Sunrise, Solar Noon, and Solar Midnight. Many updates to help and glossary, reorganized menus, a new FAQ section, all with larger type than before. We fixed a crash that occurred if you ran 2.0 in iOS 7 and tapped on the date, and corrected some contrast display issues in the Summary screen. Plus lots of other minor details and performance enhancements as well. Attention Sol: Sun Clock version 3.0 users: If you are using the "persistent" (sound until dismiss) alarms, avoid the first 3 and the last alarm sound. The fix will arrive with 3.0.1 shortly. 3.0 11/21/2013 Minor bug fixes and performance increases. 2.0.1 08/27/2013 New features added: * iPhone 5 screen support * iPad landscape mode * bookmarks for location mode * alarms have on/off switch * shows sun altitude and azimuth * swipable date transitions * swipable info area below date on iPhone * new displays for iPad * improved performance * updated graphics and UI * quick-hints tutorial * all known bugs fixed 2.0.0 08/06/2013 Fix to crash on iPad (when changing the date) that was introduced in 1.2.1. 1.2.2 09/28/2012
