Remember where you put it.

How it works

1. Put something down, and save the spot. The app records where you are, which floor you are on, a photo of the exact spot, and whatever note you want to leave yourself.
2. Forget about it entirely. That is the point. Everything is stored on your phone and stays there, whether or not you ever open the app again.
3. Come back and it points the way. Distance and direction while there is ground to cover, then the floor to travel, then the photo and the note for the last few metres.

What it will not pretend

GPS puts you within roughly 5–15 metres outdoors, and considerably worse indoors. So the app takes you to the right room, not the right shelf — the photo and the note are what close the final gap. When it does not know something, it says so instead of inventing a number: no assumed floor, no arrow drawn from a direction it never had.

Floors, honestly

An iPhone's barometer can tell one storey from another, which GPS cannot. It works by comparing the pressure where you are against a reference taken at ground level in the same building, so you set that reference once while standing on the ground floor and it stays good for a few hours. Weather moves air pressure enough to matter after that, so the app expires the reference rather than quietly guessing wrong.

Your data stays yours

• No analytics, no tracking, no third-party SDKs.
• Everything works fully offline. Sync is optional and off until you turn it on.
• Turn it on and your phones share one account — no email address, no password, no personal detail of any kind.
• Your positions and photos never leave your phone except to that account, which only you can reach.

Try it

Put That There is an iPhone app, currently in private beta through TestFlight while it gets used in real houses.

Join the beta

You will need Apple's free TestFlight app installed first. Beta places are limited while the app is being tested.
