Shift Worker is designed for people who need a quick and easy way to enter and view their shifts. A traditional calendar is not always ideal for shift workers. Sometimes it's not easy to see your upcoming shift schedule very clearly, especially if your shifts don't fall into the traditional working week. Shift Worker solves this problem and turns the frustrating task of entry into a quick and easy experience. Shift Worker allows you to create your own types of shifts by combining visually-attractive icons with letters/numbers so that they can be easily identified at a glance. By including a range of icons (such as suns and stars for day and night shifts) in a variety of colors, any combination is possible for all types of shifts. Entering shifts can be done quickly by simply selecting a type of shift and tapping on each date it occurs. An entire month of shifts could be entered in seconds, an entire year in a few minutes! In addition, Shift Worker allows you create multiple calendars to see friends and family shifts! You can send your shifts to others so they can also see your shifts at a glance as an image or in their copy of Shift Worker. To make things even simpler, you can even save your shifts to your iPhone/iPod's background so that referring to your upcoming shift schedule is as simple as picking up your iPhone/iPod. Shift Worker also includes the ability to create colored personalized notes for each date. Notes can be used anytime additional information needs to be added to a date. FEATURES: - Create a virtually unlimited amount of shift types - Enter shifts on the calendar months in advance in seconds - Add your rotation and automatically fill the calendar in a few simple steps - Show friends and family shifts using multiple calendars - View the calendar in timeline format to see your shift flow at a glance - Create colored personalized notes for any date on the calendar - Include week of year or week 1/2 alternating pattern on calendar - Jump to any month by using the "Goto" button - Save a month's worth of shifts to your background - Share your shifts to others via email, messages and social media. - Import other Shift Worker shifts and view them all within the one app - No ads!

Simple Calendar is a calendar app that works directly with your iCloud, Google and Microsoft calendars, with clear monthly, weekly and daily views, color coding, widgets and repeating events. Our design philosophy is all about simplicity and ease of use. Simple Calendar comes with various customization options, including font size — use the style that suits you best. In this calendar app, you can use the sharing features of iCloud Calendar and Google Calendar, making it easy to share schedules with family, partners, and colleagues. It's perfect for those looking for a minimalist calendar app focused on functionality instead of extra (and sometimes unnecessary) features — for work, family, shifts, school and travel. [List of Functions] · Share schedules with iCloud and Google Calendar · 15 Home Screen widgets · Next event on your Lock Screen · Font size adjustment (10 options) · Weekly (7 days · 5 days · 3 days) display · Daily display · Color coding for different calendars · Add notes, URLs, and maps · Sync with other scheduling apps · Event templates, history and search · Add an event to multiple days at once · Daily summary notifications · Restore deleted events from the Trash · 50 theme colors and a changeable app icon · Set your favorite photo as the wallpaper · Background colors for dates · White, black, or colored text for events · Set any day of the week as a day off · Change the start day of the week · Display week numbers · Lock with passcode [Function Details] ■ iOS Calendar This app uses the built-in iOS calendar system. Events made with this app will be synchronized with other scheduling apps and the iOS standard Calendar app. Your events are stored in your own calendar account (iCloud, Google, etc.), never on our servers. If you switch phones, simply sign in again and everything comes back — no account registration needed. Events sync to iPad automatically and can be viewed on a Mac or PC via iCloud.com. ■ Adjust Font Size You can choose from five font sizes of extra-small, small, medium, large, and extra-large. You can also choose light or bold text for better readability. ■ Monthly, Weekly, and Daily Calendar With one tap at the bottom of the screen, you can switch between monthly, weekly, and daily display. Switch the weekly calendar to a 7-, 5- or 3-day display to find what is right for you. A list of the day's events can be shown under the monthly calendar. ■ Color Coding You can create separate calendars according to different schedules, such as work and home. Then, you can manage them clearly by color coding them. For each calendar, you can choose everything from its color to white or black text. ■ Secure Passcode Lock You can securely lock the app with a passcode, Face ID or Touch ID if you don't want anyone to view your calendars. ■ Notification Settings You can set up notifications for scheduled events at the event time, as well as 5 min, 15 min, or more prior to the event, so you don't miss important plans! Get a summary of today's events in the morning or tomorrow's events the night before. Over 21 million downloads, 4.6 user rating (as of August 2026). [Note to Users] Since this calendar app uses the standard function of the iOS calendar, events older than one month may no longer appear on your device with the default settings. If you want to keep past events, please follow the procedure below after installing the app. 1. Open the iOS Settings app. 2. Tap "Calendar". 3. Tap "Sync". 4. Select "All Events". For details, see "Help/FAQ" in the app. [Help / Inquiries] Please visit "Help/FAQ" from the settings screen of the app. If this doesn't help, please contact us through "Contact Us" from the settings screen. We can respond much faster this way than to app reviews. [Terms of Service] https://komorebi-studio.com/tos_en.html [Privacy Policy] https://komorebi-studio.com/policyredirect.html
