PlushDays is a little plush desk calendar for your iPhone: a big date, this month's plush friend standing beside it, and your week and today's events below. It also keeps the days you're waiting for, each with a plush friend counting down with you. A PLUSH FRIEND EVERY MONTH • 22 plush friends, one for each month: Bruno, Bobble, Woolly, Peachy and more • They breathe and blink, and bounce when you tap them • The app's colors follow this month's friend • You choose who gets which month on the Companions tab: tap to pick, press and drag to swap, or shuffle the year • Companion Days counts how long each friend has kept you company, with the top three on a podium YOUR DAYS • A little line under the date that changes with your day: busy or free, Monday or Friday • Swipe to flip through weeks, or pull down to see the whole month YOUR EVENTS • Reads and writes the Calendar on your iPhone, including iCloud and any accounts you've added in Settings • Add, view and delete events; edit them in the familiar system editor • Choose which calendars to show • Turn on reminders in Settings for a heads-up before each event, as early as you like COUNTDOWNS • Birthdays, anniversaries, exams, the day you set off... keep the days you're waiting for, and watch them come closer • The nearest one stands at the front, with a little line for today under it • Each countdown gets a plush friend of its own, in a little outfit or with a prop; by default, the friend of its month • Count down once, or repeat every year, month or week; days that have passed show how long ago they were • Turn any countdown into a share card to save as an image or send to a friend • A reminder on the day or the day before, at the time you choose WIDGETS AND STANDBY • Plush Desk: small and medium Home Screen widgets (medium lists what's next), plus three for the Lock Screen • Plush Month: small and medium, the whole month at a glance • Plush Countdown: a small Home Screen widget with the days left, and you can choose which countdown it shows • Charge your iPhone on its side for StandBy: Plush Desk on the left, Plush Month on the right, and you have a bedside calendar MADE FOR IPHONE DUO • Closed, it's the page you already know • Open it sideways: the month on the left, your day on the right • Stand it up, and it's a little desk calendar ALSO • Light and Dark Mode • Four app icons: Bruno, Bobble, Woolly and Peachy • VoiceOver support, and text that grows with your system text size • English, Simplified Chinese and Traditional Chinese PRIVACY No account, no sign-in. PlushDays never goes online and collects no data. Reminders are notifications from your iPhone itself, so they stay offline too. Your events stay in your own calendars, even if you delete the app. Countdowns are stored only on this iPhone and are deleted with the app. Without calendar access, the desk shows just the date and a plush friend, and countdowns still work.
