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 talk to you—every cat has a personality of its own, so each moment together feels a little different. ・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. Lock Screen widgets are available too, so you can check the day count without unlocking your iPhone. ・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. 【Meet the Cats】 Included for free: Coco. More cats can be unlocked from the Cat Shop in Settings. Each cat is a one-time purchase and yours to use forever—no subscription required. Want to bring several home at once? Choose a pack for a better value. 【About Purchases】 CatDays is free to download, with all core features included. Additional cat characters are available as one-time purchases with no subscription fees. You can restore previously purchased content anytime from “Restore Purchases” in Settings.

Look forward to the birthdays of the people you love. Berrily is more than a reminder that fires on the day. It was made so that the time spent waiting for a birthday is a pleasure in itself. Add a birthday and Berri the bear waits with you. While the day is still far off, he reads with a warm drink. A week before, he picks a gift. Three days before, he bakes the cake. The day before, he hangs the bunting. And then, the party. Every time you open the app, you can see the day coming closer. FOR YOU IF - There are people you want to celebrate: kids, a partner, parents, friends - You would rather look forward to the day than notice it on the morning - You want a calm app with no account and no ads WHAT IT DOES - Shows who is next, how many days are left, and how old they are turning - Puts people who share a birthday on the same card - Keeps a note per year: gift ideas, the cake, what you want to say - Lets you add a photo, or pick an icon that follows your theme colour - Imports the birthdays already saved in your contacts REMINDERS Choose 30, 14, 7 or 3 days before, the day before, or the day itself. Pick the time. Turn off the ones you do not need. WIDGETS See Berri and the next birthday on your Home Screen and Lock Screen without opening the app. YOUR DATA No account. No ads. No tracking. Your birthdays are kept on this iPhone and in your own iCloud, nowhere else. On a new phone, sign in with the same Apple Account and they come back. PRICE Free for up to 10 people. One purchase for unlimited people, no subscription. Reminders, widgets and iCloud sync stay free. Available in English, Japanese, German and Traditional Chinese.
