If you need to quickly find out the area of a room, roof, ceiling, or any shape in just a few clicks on the screen, this application is for you. If your shape has right angles, the program will correct them automatically. If the angles are not right, go to settings and apply angle correction, then from the very beginning of construction, you can create any shape. Move the angles to the desired location by long-pressing, merge walls by switching to the displacement mode at the bottom of the screen. If you have suggestions for improving the application, write to us, we will definitely listen to your opinion. (There is information in the settings on where to write.) We really hope that our application will make your life a little easier! Good luck!

About

Just These

Features
Read full description

You hand someone your phone to show them one photo. Then they swipe. Just These fixes that. Pick the photos you want to show, tap Start Handover, and pass the phone across. Your guest sees those photos and nothing else — no swiping into last week, no sliding into your camera roll, no accidental discoveries. Getting back out takes your Face ID, Touch ID, or PIN. HANDOVER MODE Choose photos in any order. The person holding your phone can swipe and zoom through exactly that set, and nothing more. The back gesture is sealed off, a stray swipe from the edge of the screen won't take them out of the app, and leaving Handover Mode takes your Face ID, Touch ID, or PIN. Force-quitting does not help either: the app reopens locked. SHARE WITH ME Your guest loves one of the photos? They tap "share with me" on it, or ask for them all. When you have your phone back, you see what they asked for, untick anything you'd rather keep, and send the rest by AirDrop. They never touch your contacts or your other apps. STYLE IT Your guest can say how they want a photo, too. They tap "style it", swipe through nine looks inspired by film cameras and early-2000s digicams (soft film, disposable, night film, noir and more), crop it for a post or a story, and tap Done. When you have your phone back, you see each photo exactly as they styled it and send it that way, or flip one switch to send your originals. Your originals never change. QUICK HANDOVER Most handovers are about something that just happened. One tap covers it: - Last 10 minutes — the photos you literally just took - Last hour, today, yesterday - Last 10 or last 25 photos - All Allowed Photos, if you've given Just These only some of your library No scrolling, no hunting. Shoot, tap, hand over. COLLECTIONS Showing the same trip to everyone? Tap the bookmark to save your picks under a name, then hand the same set over again any time in one tap. NOTHING IS RECORDED No viewing history, no record of what was shown to whom. What your guest asks for, and how they styled it, is forgotten as soon as you've answered, and a styled photo is made only at the moment you send it. Collections are just a list of which photos, kept on this phone. Your selection stays put after a handover, so you can show the same photos to the next person — and Clear & Exit puts it down when you are done. BUILT FOR ONE-HANDED SPEED - Tap photos to select — they are numbered in the order you picked, so your story stays in order - Drag to rearrange them in the tray along the bottom - Long-press and sweep to select a run of photos at once - Pinch to zoom the grid from 2 columns out to 6 - Photos are grouped by month, with a scrubber down the edge you can tap to jump straight to any month LOCKED FROM THE START Just These asks for your passcode when it opens, and again after it has been closed for a while. Force-quitting the app during a handover does not get anyone anywhere: it reopens locked. PRIVACY THAT ISN'T JUST A PROMISE - No internet access. The app ships with no networking code, so it cannot upload your photos — whether or not you trust us. - No account, no cloud, no sign-up, no analytics, no ads. - Your PIN is never stored. Only a salted SHA-256 hash of it is kept, which cannot be turned back into your PIN. - iPhone does not let apps block screenshots, so Just These warns you the moment one is taken during Handover Mode. - Your photos are read to show them to you, and sent only when you tap Share. Where your data is concerned, that is the entire feature list. Share your phone, not your privacy.
