OurDays is a shared calendar built for exactly two people. Not a family calendar, not a group: just you and your partner. TWO LANES, ONE DAY Your schedule on the left, theirs on the right, each headed by your avatars and the day's event count. Plans you share are drawn as a single block across both lanes, so you can tell at a glance when you're both free. YOU CHOOSE WHAT TO SHARE Pick which of your iPhone calendars your partner can see, and whether they see full details or just "busy". Anything you don't select is never shared. By default only events from your pairing day onward are shared. TALK ABOUT YOUR PLANS Comment under any event. Their bubbles on the left, yours on the right. The Activity tab gathers both of your comments by event, with an unread badge. INVITE EACH OTHER Send a plan as an invite inside the app. When your partner accepts, it's added to their calendar, and the status stays in sync for both of you. MADE FOR TWO • Pair with one iCloud share link • Nicknames and photo or text avatars that sync to your partner • A private pet name for your partner that only you can see • "Day N together", counted from the day you paired • If a third person ever joins through an old link, OurDays asks you what to do instead of silently swapping partners YOUR DATA STAYS YOURS OurDays has no server and no accounts. Your data lives on your devices and syncs only through a private iCloud share between the two of you. No ads, no analytics, no tracking. FREE AND OPEN SOURCE The full source code is on GitHub. With no servers to rent, the only running cost is the yearly Apple developer fee, which is why OurDays can stay free. Requires iOS 18 or later and an iCloud account on both iPhones.
