Tempo. A calendar in tune with your day. Tempo is a clean, lightweight calendar designed to make everyday actions quick and easy. We focus on a natural feel over flashy features, an at-a-glance view over complicated settings, and a clean interface. - A minimal layout that’s easy to read - Seamless integration with Apple Calendar - Automatic iCloud sync Key features [Full Apple Calendar integration] Tempo lets you view and edit events from every account connected to your device’s system calendar, including iCloud, Google, and Naver. There’s no need to move your data or create a new account. [Automatic iCloud sync] Events added on your iPhone automatically appear on your iPad and Mac. Events sync through your connected calendar accounts, while individual event colors, date ranges, and other details set in Tempo sync through iCloud. Add an appointment on your iPhone during your commute, then organize your schedule on your Mac at the office. Switch devices and pick up with the same events, without any extra steps. [Monthly and weekly Home Screen widgets] Add a large monthly calendar widget to your iPhone or iPad Home Screen. See a whole month of events at once, switch months, and add events right from the widget. Tap a date to open that day in your calendar. [Lock Screen widgets] Check a two-week calendar that includes today, or see upcoming events, right from your iPhone Lock Screen. Spot the days with plans or view up to three upcoming events to get a quick sense of your day without opening the app. [Custom colors for individual events] While the system calendar assigns colors by calendar, Tempo lets you choose a color for each event. Use red for important meetings, yellow for family plans, and green for study time to see what matters at a glance. [Date range highlights] Outline multi-day periods such as time off, business trips, vacations, or exams with a visual border on your calendar. Unlike a regular event entry, this makes the entire date range easy to see at a glance. [30-day event recovery] Accidentally deleted an event? Don’t worry. Tempo safely keeps snapshots of deleted events for 30 days. Bring them back at any time during that period from "Restore events" in Settings. [Notifications and quick access] Get notified at the time you choose so you don’t miss an important appointment. Tap a notification to go straight to the event. Tempo integrates smoothly with Apple’s notification system for a simple, familiar experience. [Event search] Quickly find events by title. Search ignores differences in case and diacritics, so even part of a word can help you find a matching event. What Tempo stands for [Smooth interactions] Every interaction should feel instant. Tempo focuses on natural, lightweight responses rather than heavy animations or complicated screen transitions. [Minimal design] Essential information is clear, and unnecessary elements are left out. By reducing visual clutter, Tempo helps you focus on your events. [At home in the Apple ecosystem] Tempo follows the design language of iOS, iPadOS, and macOS. It makes natural use of Apple’s built-in calendar, notifications, widgets, iCloud, and more. On the move or at your desk, keep your day flowing with Tempo. Tempo. A calendar in tune with your day.

About

Don't Forget Notes

Read full description

Don't Forget Notes is a simple notepad for the things you want to keep in sight. A shopping list, the keys you need before leaving, or one thing to do today: put a note where you will see it without searching for the app. WRITE AND KEEP IT Notes save automatically as you type. Create several notes and find them with search. No account is needed, and writing, editing and reading notes work offline. READABLE STICKY NOTE WIDGETS Choose the note to display, one of three text sizes, and a white, yellow, gray or black background. Place the widget once. Later edits update that same note in the widget; move it on your screen only when you want a different position. UNDO AN ACCIDENTAL DELETION Restore deleted notes from Trash for 30 days. Widget updates may take time depending on your device and the operating system. NOTES ON THE LOCK SCREEN Add rectangular, circular or inline note widgets to the iPhone or iPad Lock Screen. These small widgets are best for short notes and the first few lines. Choose the position and note in your device's widget editor. YOUR NOTE TEXT STAYS ON YOUR DEVICE We do not send note text to our servers or advertising SDKs. A banner appears below the notes list, with no ads in the editor or widgets. The ad SDK may process identifiers, interactions and diagnostic data. Required advertising choices are provided in relevant regions. Anyone looking at your screen may read widget notes. Do not display passwords or other private information. Visibility while locked also follows your device's privacy settings. Uninstalling the app may erase notes. Contact: notes@dotnull.co.jp
