CatDays is a minimalist countdown and day counter app.
Choose a cat for every day that matters. It’ll wait with you for what’s ahead and remember how far you’ve come.
Whether you’re looking forward to something in the future or marking a journey already underway, leave the counting to a cat. Every time you open CatDays, it’ll be right there, counting with you.
・Two ways to count: down and up
Count down the days until something ahead, or count up the days since something began. Birthdays, trips, anniversaries, exams, or every day since you gave something up—CatDays can keep track of them all.
・The days you’ve lived are worth keeping
Every season of anticipation and perseverance deserves to be remembered. One-time countdowns automatically move to Memories after they end. When a chapter comes to a close, you can stop a count-up on the exact day it ended. If you want to keep going, you can bring it back and continue counting anytime.
・A cat of your own
Every date can have its own cat. Give it a tap and it’ll strike a new pose and speak in its own distinctive voice—five cats, five personalities, each offering a different kind of companionship.
・Your cat will remind you when it matters
When an important day is near or arrives, your cat will send a gentle reminder. It’ll also check in when a count-up reaches a milestone worth marking. Turn reminders on or off and choose your preferred reminder time in Settings—quiet and never intrusive.
・Home Screen widgets put your cat where you’ll always see it
Choose from Small and Medium countdown widgets and select the dates you want to display. A Medium widget can also show up to three countdowns at once. Your cat will change poses from time to time, so every glance feels a little different. Tap a widget to jump straight to the details in CatDays—a companion you can see every day.
・Cat calendar widgets for every day
Choose from a variety of cat calendar widgets featuring month, today, and week layouts. Pick your favorite cat and let it keep you company on your Home Screen every day.
・Automatic iCloud sync
Your countdown data can sync automatically through iCloud across devices signed in to the same Apple Account, so it stays with you when you switch phones. Your content is stored on your device and in your personal iCloud and is never sent to our servers.
・Clean, calming, and free from distractions
No ads, no subscriptions, and no complicated setup. Open CatDays and all you’ll see are your cats and the days that matter to you.
