Tup' Where?
Read full descriptionHide full description
You sent your friend home with leftovers, and now your favorite container is somewhere in their kitchen. Or their roommate's. Maybe it's at the office? Tup' Where? makes sure you never have to guess again. When you lend a container, snap a photo of the person holding it. The app remembers who has what. When they bring it back, tap once to mark it returned. That's the whole app. WHY PEOPLE USE IT • Stop buying replacements for boxes you already own • Know instantly who still has your containers • See how long each person typically takes to return them • Skip the awkward "which one was mine?" moment • Works for lunch containers, potluck dishes, baking pans, baby bottles — anything you lend HOW IT WORKS 1. Someone's taking food home. Tap +. 2. Snap a photo of them holding the container. 3. Tell the app how many you lent. 4. When it comes back, tap the return arrow. No setup. No accounts. No onboarding quiz. PRIVATE BY DESIGN This is where we're different. Tup' Where? has no servers. None. Your photos, names, and notes never leave your iCloud. We literally cannot see your data because we never receive it. No analytics. No trackers. No third-party SDKs. We checked twice. Your container history is as private as your photo library — because it lives right next to it, in the same iCloud. The people-stats view shows each person's average return time, their outstanding count, their history. All of that is calculated on your phone, from your data, for your eyes only. Nobody else sees it. Not the people being tracked, not us, not anyone. FAQ Do I need an account? No. Open the app and start. Where are my photos stored? In your iCloud, under your Apple ID. We do not run a server. If you delete the app, the data goes with it. Will the people I'm tracking know? Not unless you tell them. This is your list, for your kitchen. Can I use it for non-food things? Yes. Books, power tools, baking dishes, party supplies, the good Pyrex. Anything that leaves your house and is supposed to come back. Tup' Where? is a small, personal app built to solve one annoying problem cleanly. If it helps you stop buying new containers, we did our job. Questions?
