YardTime keeps neighboring dogs from meeting at the fence. If your dog and the dog next door bark up a storm whenever they're both out back, YardTime gives you a shared, real-time yard status so you can take turns — no more changing a group-chat photo to "dog" and hoping everyone notices. One tap tells your neighbors the yard is taken. A timer frees it up automatically. And the moment it's clear, everyone gets a heads-up. WHY YOU'LL LIKE IT • One-tap status — "Let Rex out," and your neighbors know instantly. • Timers that check in — pick 15, 30, or 60 minutes (or open-ended). When time's up you get a nudge to extend or bring them in, and the yard frees itself if you've moved on. No more forgetting to flip it back. • "Yard is clear" alerts — get notified the second it's your turn, and let your dogs out with one tap right from the alert. • At-a-glance widgets — home screen and lock screen show clear or occupied without opening the app. • Live Activity — a countdown on your Lock Screen and in the Dynamic Island while your dog is out. • A shared recent-activity feed — who let dogs out and when the yard cleared, the same on every phone in the group. • Hands-free — say "Hey Siri, let the dog out," or map it to the Action Button, for when you've already got a dog by the collar. • A heads-up before your dog goes out on top of a neighbor's — in the app, from Siri or an NFC tag, on the widget, on your watch. Nobody's dogs meet at the fence by accident. SET UP IN UNDER TWO MINUTES Create a group, share one invite link, and your neighbors are in. No sign-ups, no passwords — it's tied to your iCloud. PRIVATE BY DESIGN Your yard status lives in your own iCloud and is shared only with your group. No accounts, no ads, no analytics, no tracking, nothing sold. Ever. Built for a few households on a quiet street — not the whole internet.
