Waiting 4 is now live on the App Store. It does one thing: it tracks the things other people owe you, and quietly tells you how long it's been.
The reply your landlord never sent. The $40 your friend still hasn't paid back. The package that's been "shipping soon" for two weeks. The recruiter who said "next week" — three weeks ago.
You know these loops. They live in the back of your head, and they cost more attention than they deserve. Waiting 4 gives them one place to sit, so your head doesn't have to hold them.

What it is
One screen. A list of open loops, longest-waiting first. Each item is exactly four things: who, what, since when, and how often you'd like a nudge. The elapsed time — "12 days" — is the biggest thing on every card, because that number is the product. The app's entire job is making the invisible passage of time visible.
When something resolves, you swipe right — Got it — and the item is gone. Not archived. Gone. When you decide something isn't worth waiting for anymore, you swipe left — Let it go — and it's gone too. There is no history tab, no completed-items graveyard, no stats page. Closure means closure.
What it deliberately isn't
Every feature request for an app like this pulls in the same direction: become a to-do list. Add projects. Add tags. Add priorities. Add notes. Add AI.
We wrote the refusal into the design system as a rule: any feature that tracks what you must do is rejected by design. This app only tracks what others owe you. That single constraint is why it stays one screen — and why it doesn't add to the pile of obligations your other apps already represent. Your task manager tracks your debts to the world. Waiting 4 tracks the world's debts to you. It's the anti-productivity app.
The tone follows the same principle. Nudges are factual and on your side: "Still waiting on Jake — 12 days." No exclamation marks, no red badges, no guilt, no streaks. The point isn't to make you act — it's to confirm you're not crazy: it really has been three weeks. Nudges respect quiet hours, too. Nothing lands before 9:00 or after 21:00.
Zero setup, and your data stays yours
There's no account, no server, no onboarding. First launch is an empty list and one hint line. Adding an item is one tap and one line of typing.
Everything lives on your device. Sync across your iPhones runs through your own iCloud — we never see your list, because there is nothing of ours for it to pass through. No analytics on your items, no tracking. The only data that ever leaves the app is a crash report or feedback you explicitly type and send.
Small, native, considered
Waiting 4 is built iOS-native first: system fonts, system materials, real haptics, local notifications. There's a Home Screen widget that shows your longest-waiting loop (or, on a good day, "Nothing owed."), and a share extension — share a message or a link from any app, and the add sheet opens prefilled. Saw the "your refund is processing" email? Two taps and it's a loop with a clock on it.
The fifth app
Waiting 4 is the fifth product in our portfolio, and the clearest expression yet of how we like to build: pick one sharp problem, refuse the feature creep, ship it small, and let the design constraints do the work. It sits alongside Acornonaut, Snapcipe AI, NextFerry, and Fitports — five apps, each deliberately narrow.
If someone owes you something right now — and someone always does — put it on the list. Then get on with your day. The clock runs so you don't have to.
