Use your Galaxy Tab as a drawing tablet.

If your Galaxy has an S Pen, it already has the hardware of a pen tablet. PenCast sends the pen to your Mac or PC — pressure first, no ads, no subscription.

The Android app is on its way to Google Play; the desktop app pairs with it. Email me for a heads-up.

Which Galaxy devices?

PenCast is built around Samsung Galaxy devices that support an S Pen:

Galaxy Tab S tablets — the usual choice: big screen, S Pen support.
Galaxy S Ultra phones and Galaxy Note phones — a phone with an S Pen can be the tablet too.
Android 7.0 or newer on the Galaxy (the app's minimum).

There's no device list inside the app — it simply reads what Android reports as a stylus. That means other styluses might work, but only Samsung S Pen devices are what I design around. I haven't published a per-model tested list yet; check Samsung's spec page for S Pen support on your exact model and try the free version first.

How a Galaxy Tab becomes a pen tablet

Your tablet runs the PenCast Android app (coming to Google Play); your Mac or PC runs the free desktop app. The tablet sends small pen packets — position, pressure, tilt, hover — and the desktop app turns them into native pen input. No video of your screen is sent, so your computer monitor stays the canvas and the tablet is the surface you draw on.

Install the desktop app: Mac (.dmg) or Windows (.exe).
Install PenCast on the Galaxy (coming soon to Google Play).
Scan the QR code, or plug in a USB cable with USB debugging on.
Draw in a pen-aware app on your computer.

Honest limits

Your tablet won't show your canvas. PenCast is a pen tablet, not a screen mirror: you look at your computer and draw on your Galaxy.
WiFi mode isn't encrypted yet. Use USB, Bluetooth (Pro) or a network you trust.
Installers aren't signed yet. The Mac app isn't notarized and the Windows installer isn't code-signed, so each asks for one extra click.
Apps differ. Compatibility depends on your drawing app and its pen settings. I haven't published a tested-apps list yet — try the free version first and tell me what works.
The Android app is coming to Google Play. The desktop app pairs with it; until it's live there's nothing to pair with.

Questions

Which Galaxy devices work with PenCast?

PenCast is built around Samsung Galaxy devices that support an S Pen — for example Galaxy Tab S tablets, Galaxy S Ultra phones and Galaxy Note phones — on Android 7.0 or newer. The app has no device list: it reads whatever Android reports as a stylus. Check Samsung's spec page for S Pen support on your exact model, and try the free version first.

Does it work with a Galaxy Tab A or a tablet without an S Pen?

PenCast is designed for a pressure-sensitive stylus. Tablets without S Pen support are not the target, and I don't claim they work.

Do other Android styluses work?

They may, if Android reports them as a stylus, but they aren't officially supported and I haven't tested them.

Does the tablet show my computer's screen?

No. PenCast is a pen tablet: the pen goes to the computer and your computer screen stays the canvas.

Is it a Wacom replacement?

It turns a device you may already own into a pen tablet, which can save you buying dedicated hardware. A dedicated tablet has its own driver and a wired connection, so expect differences, especially over WiFi.
