Multilevel vs PIPin

Displays precise angle between two or more devices, making it possible to perfectly align physical objects in relation to one another. Measuring relative level comes in handy for aligning items that have significant distance or physical obstruction between them. Sometimes there’s a need to determine angle between separate objects, rather than to see how flat they lay relative to the planet’s surface. The app uses Bluetooth to broadcast its magnetometer’s data and to observe position values of other devices that run Multi Level, then it uses that data to compare and display its own physical orientation in relation to other devices. The communication is done without having to pair the devices — there’s no need to tap on anything or deal with PIN codes, everything happens automatically. With only one device running the app, Multi Level works as a conventional bubble level. Position measurements can be observed from desktop and laptop computers using the macOS version of Multi Level. You don’t need to purchase this app more than once, as long as all devices use the same Apple ID.

Keep an eye on — and control — any Mac window right from your iPhone or iPad. Pin a window on your Mac with ⌥⇧X and it instantly appears on this app. Watch an AI agent work, keep a doc or dashboard visible while you do something else, or take over and drive your Mac from the couch. You'll need the free PIPin Mac app — get it at pipin.jylljy.top. • Remote control. Tap to click, long‑press to right‑click, two‑finger swipe to scroll. Switch to trackpad mode for relative cursor moves. iPad trackpad and Bluetooth mouse scroll work too. • Type from anywhere. The on‑screen keyboard ships with sticky ⌘ ⌥ ⌃ ⇧ modifiers and arrow / esc / tab / delete keys, so Cmd‑Tab, Cmd‑C, and friends just work. • Real iOS Picture‑in‑Picture. Leave the app and the stream shrinks into a system PIP window that stays on top of anything else you do on iPhone or iPad. • Local‑only. Streams over your Wi‑Fi network via MultipeerConnectivity. Nothing touches the cloud. • Zero account. Open the Mac app, open this app on the same Wi‑Fi, tap your Mac, done. • Multiple PIPs. See every pinned window in a grid, tap to zoom. • Pinch and pan on the detail view; double‑tap to fill the screen.
