Version 2.0

What's new today

The two biggest upgrades since launch: appWindow can now reach into the window it's mirroring, and it no longer stops at one.

New

Interact Mode — control PiP without switching to it

Flip a switch on any PiP panel and it stops being a read-only mirror. Click buttons, follow links, and type — delivered straight to the real window, even while it's hidden behind other apps or sitting on a different desktop. The app you're actually using never loses focus.

New

Run up to 5 PiPs at once

Start no longer toggles closed — it just keeps adding. Float a call, a dashboard, and a video tutorial simultaneously, each independent and each interactive. Close whichever's under your cursor, or clear every panel with one shortcut.

Previous updates

Everything shipped before 2.0 — still fully supported.

Version 1.1
  • Multi-window picker — apps with several windows open (WhatsApp main + call, multiple Chrome windows) let you choose which one to mirror
  • Double-click PiP to hide, an optional Settings toggle
  • Select a specific area — drag a rectangle over a dimmed overlay to mirror only that region, across multiple monitors
Version 1.0
  • Initial release — instant PiP for any app with one shortcut, automatic WhatsApp call detection, free dragging & resizing, always-on-top toggle, and fully customizable shortcuts
Features

Everything you need, nothing you don't

appWindow is a quiet menu-bar utility with a handful of features that all do exactly one job well: keep the window you care about visible — and now, usable.

Instant PiP, any app

Press one shortcut and the frontmost window — a browser, Spotify, Zoom, anything — becomes a floating Picture-in-Picture panel. If that app has multiple windows, pick the one you want first.

Interact with the real window

Turn on Interact Mode and click, follow links, or type directly into the source window — without switching to it, activating it, or losing your current focus.

Up to 5 PiPs, independently

Float as many windows as you need at once. Start keeps adding instances; dedicated shortcuts close whichever's under your cursor or clear them all.

WhatsApp call detection

appWindow watches for WhatsApp video and voice calls and automatically offers to float the call window the moment it starts.

Drag & resize freely

Move it anywhere on screen and resize from a single corner handle — as small as 50×50 pixels, or as large as you like.

Always-on-top, your choice

Keep your PiP floating above everything, or let it behave like a normal window that other apps can cover.

Four independent shortcuts

Start a new PiP, close the nearest one, close them all, or hide/reveal everything at once — each fully recordable to whatever combo you want.

Watch what you want

Choose exactly which apps appWindow should monitor, or set it to watch every window on your Mac.

Lives quietly in your menu bar

No Dock icon, no app switcher clutter — appWindow stays out of your way until the moment you need it.

How it works

From click to floating in seconds

1

Open appWindow

It settles quietly into your menu bar — no Dock icon, no setup screens.

2

Press your shortcut

Start floats the frontmost window. If that app has multiple windows, pick the one you want — then optionally drag an area to mirror just that region. Press it again anytime to add another PiP.

3

Arrange it your way

Drag it anywhere, resize from the corner, toggle always-on-top — or flip on Interact Mode to click and type into the real window without switching to it.

4

Hide, reveal, or close

Your show/hide shortcut hides or reveals every PiP at once. Close whichever's under your cursor, or clear them all — Start only ever adds more, it never closes anything.

100% local. Nothing ever leaves your Mac.

appWindow makes zero network requests. There's no analytics, no telemetry, no account, and no server. Window detection, capture, and mirroring all happen entirely on your device.

No analytics No account required No network requests Nothing stored or sent
FAQ

Good questions

What is Interact Mode, and why does it need Accessibility permission?

Interact Mode lets you click, follow links, and type directly into the real window from the PiP mirror — even while it's inactive or sitting on a different desktop. Delivering those clicks and keystrokes to another app requires macOS's Accessibility permission, the same one screen readers and automation tools use. appWindow only uses it to forward input you give it inside a PiP panel — nothing runs in the background.

Can I have more than one PiP open at a time?

Yes — up to 5 at once. Start adds another PiP every time you use it; it no longer toggles closed. Use the close-nearest shortcut to close whichever panel is under your cursor, or close-all to clear every one instantly.

Why does appWindow need Screen Recording permission?

macOS requires this permission for any app that mirrors the contents of another window. appWindow only uses it to capture the specific window you choose to float — never anything else, and never in the background without your action.

Does appWindow only work with WhatsApp?

No. appWindow started as a WhatsApp call companion, but it now works with any app on your Mac. Use the shortcut to instantly float the frontmost window of any app, or choose specific apps to watch automatically in Settings. When an app has multiple windows open, a picker lets you choose which one to mirror.

Can I mirror only part of a window?

Yes. Turn on “Select specific area for PiP” in Settings. After you pick a window, a dimmed overlay appears; drag a rectangle over the region you want, and PiP mirrors only that area. Press Esc to cancel.

How do I quickly hide the PiP without closing it?

Use your show/hide shortcut anytime — it hides and reveals every open PiP together. You can also enable “Double-click PiP to hide” in Settings to tuck away just one panel while its capture keeps running.

Is my data safe? Does appWindow collect anything?

appWindow makes zero network requests. There's no analytics, no telemetry, no account, and nothing is ever sent anywhere — everything happens entirely on your Mac.

Why do I see an "Apple could not verify this app" warning when I open it?

appWindow is currently distributed directly rather than through the Mac App Store, without a paid Apple Developer certificate, so Gatekeeper flags it as from an unidentified developer. This is expected. Right-click the app, choose Open, then click Open again in the dialog — you'll only need to do this once.
