Oops, Paper Trail! gives you one place to keep track of the promises, follow-ups, receipts, reminders, and little details that somehow become very important three weeks later. Whether you’re waiting on a refund, following up on a repair, keeping track of a promise, handling paperwork, or trying to remember who said they’d call you back Tuesday, Paper Trail helps you keep the whole story together. KEEP TRACK OF WHAT HAPPENED Create a Paper Trail for anything you don’t want disappearing into texts, emails, screenshots, sticky notes, or your memory. KNOW WHAT HAPPENS NEXT Add reminders, follow-up dates, notes, and next steps so you can see what needs your attention—and what you’re still waiting on. KEEP THE PROOF Attach receipts, photos, screenshots, PDFs, and other files right where they belong.

Ping is the reminder app for things you actually have to do. Other reminder apps notify you once, you swipe it away, and the task dies in a graveyard of dismissed notifications. Ping doesn't work that way. When something is due, Ping pings you, and keeps pinging on your schedule until you mark it done. There is no dismiss. Only Done. JUST SAY IT Type or dictate a reminder the way you'd say it to a person: "remind me at ten to take my meds", "laundry tomorrow", "trash every monday at 8pm". Ping understands plain language and fills in the what, the when, and the repeat. ON-DEVICE APPLE INTELLIGENCE Ping uses Apple's on-device models to understand messy, human phrasing: spelling mistakes, changes of mind mid-sentence, pasted appointment texts. When something sounds important, like medication, Ping suggests pinging more often. All of it happens on your iPhone. Nothing is ever sent anywhere. RELENTLESS, ON YOUR TERMS You choose how often Ping re-pings (every 5, 15, 30, or 60 minutes) and when it's allowed to give up, or set it to never give up. A live countdown shows the next ping. Repeating tasks roll forward when you complete them. PRIVATE BY DESIGN No account. No server. No analytics. No tracking. Your reminders live in a local database on your device and die there when you delete them. Ping is for medication, deadlines, dishes, laundry, calls you keep postponing, and everything else you've ever swiped away and forgotten. Stop dismissing. Start doing.
