OneThing
Read full descriptionHide full description
1Thing helps you cut through the noise and focus on what truly matters each day. The concept is simple: choose ONE important goal, lock it in, and give it your full attention. When you're done, close it with context — how much impact it had, how difficult it was. If you gave up, close it honestly and move on. ONE GOAL. NOT A LIST. Most productivity apps overwhelm you with tasks. 1Thing does the opposite — it forces you to ask: "What's the ONE thing that, if I do it today, makes everything else easier?" FEATURES · Set one meaningful goal per day · Lock it in with a two-question validation · Mark it as achieved or resigned with reflection · Weekly history to track your progress · Home screen widget (small and medium) · Daily reminders to define and close your goal · Motivational quotes to keep you focused · Beautiful, distraction-free design YOUR DATA. YOUR DEVICE. Everything stays on your iPhone. No accounts, no cloud, no tracking. Just you and your one thing. 1Thing — because less is more.

Because “I’ll remember” is not a filing system. 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. FIND IT WITHOUT PLAYING DETECTIVE Search your Paper Trails when you need to remember a name, amount, reference number, promise, update, or detail. KEEP THE HISTORY Add updates as things happen. When something is finally handled, mark it resolved without losing the record. STAY ORGANIZED WITHOUT MAKING ORGANIZATION A SECOND JOB Paper Trail is designed to be simple, friendly, and easy to use—because the thing you’re trying to deal with is probably annoying enough already.
