Clover is a sheep. She lives in a meadow, and she does not need you to talk to her. Choose how long you want to leave your phone alone — a short wander, a good ramble, or a long walk — and press one button. The apps you picked go away for that time. Clover keeps wandering while you're gone, and she finds things. When the time is up, your apps come back and a card appears in your hands, handwritten, naming everything she found. The card is yours to keep. HOW IT WORKS Pick your apps once. Clover uses Apple's Screen Time to put them away — the selection never leaves your phone, and we never see which apps you chose. Pick an outing. Three lengths, named for what she does with the time rather than for the clock. A longer outing finds more. That is the only reason to choose one. Watch, or don't. She keeps wandering either way. If you happen to open the app mid-outing, you might catch the moment she stops to look at something, and a line in her handwriting floats above her. If you don't, you miss nothing — the find is reported at the end regardless. Check the Lock Screen. The Live Activity shows her hopping through the meadow and the last thing she noticed, so you always know she's still out there. Keep the card. Every outing ends with one memory, kept in a journal that only ever grows. THINGS THIS APP WILL NEVER DO No streaks. A streak is a thing that can be broken, and this app is built on the idea that breaking is fine. No punishment for stopping early. Nothing withers, nothing dies, nothing is taken back. If you need your phone, take your phone. Clover will be in the meadow later. No guilt notifications. No "Clover misses you." No pressure to come back. No ads. No pop-ups. Nothing sold to you in the middle of a quiet moment. No account required. The meadow, the journal and your app selection all live on your device. WHO IT'S FOR People who have tried a hard app blocker and quietly deleted it after four days. People who want to study, read, sleep or eat dinner without their phone in reach. People who don't want a productivity dashboard telling them they failed — just somewhere pleasant for the time to go. Focus, screen time, deep work, digital detox, phone-free evenings: whatever you call it, the mechanic is the same. You put the phone down. Something small and good happens in your absence. You get to see what it was. A note on Screen Time: app shielding uses Apple's Family Controls and requires your permission. If you'd rather not grant it, everything else still works — the outing, the meadow, the finds and the journal all run on the clock alone.

Verdict
The clearest difference is update cadence: Clover at weekly against Paperpile's every 2 months. Paperpile's advantage is iOS requirement (12.0 vs 16.1). On price, ads, in-app purchases and device support there is nothing between them.
