If you thought the best impression pad couldn't get any better...

Take your show to the next level with

ThoughtCast PRO!

ThoughtCast is an electronic impression pad app that, when combined with a special Bluetooth sensor board, allows you to divine words, drawings, numbers, or letters, all in real time, without any assistants!

Get into your spectator's


Make it Yours!

Choose your finish (Gloss Black or Wood), choose your style (clipboard or whiteboard), and even choose from our Standard or Large size. Pick any combination and we'll build a custom ThoughtCast Pro just for you!

How Does ThoughtCast Work?

(spoiler alert)

First, Your Spectator Draws any Shape or Writes any Word using a (seemingly) normal pen.

Next, You have your phone out, and it appears to be locked (or on the home screen, or on any screen). As soon as you touch the screen, you instantly get a peek. Let go, and it goes away!

You can obtain your peek on your Apple Watch or Android Wear Watch as well. Now that you know what they wrote, you can reveal it in whatever way you'd like!

Frequently Asked Questions

Pro Sensor Board

What else comes with the Sensor Board? Any accesories?

Yes! When you purchase a Pro Sensor Board, you also receive a charging cable, a pre-gimmicked standard ThoughtCast Pen, and a few other items to facilitate the care and charging of your board. If you purchase the whiteboard model, you will receive a whiteboard marker instead of a pen.

How long does the battery last on the Sensor Board?

The manufacturer has listed the battery life as 7 hours on a full charge, but your mileage may vary. In our testing Sensor Boards last between 6 and 7 hours on a full charge when left on and connected to ThoughtCast.

How long does the battery take to charge?

In our tests, it takes about 2-3 hours to reach full charge from 0% battery.

Is the battery removable/replaceable?

Unfortunatly, no.

Can I connect multiple sensor boards to my app simultaneously?

No. Only one at a time.

Does the sensor board automatically reconnect?

On iOS, Yes. Should your sensor board go out of range, the app will alert you visually and with a vibration. Once the board comes back into range, it will automatically reconnect. On Android, this is dependant on your device. Some devices will reconnect immediatly, some will take up to 20 seconds. However, once the device is connected to the Sensor Board, it will stay connected reliably until the battery of the Sensor Board runs out.

What is the range of the Sensor Board?

Because the board connects via Bluetooth, this varies. The official answer from our manufacturer is 30-45ft, but in our tests we have achieved over 50ft of range. Be sure to test your range in your performance environment to ensure connection strength and quality when performing.

Does the Sensor Board come in a variety of sizes?

Our Pro board comes in two sizes, a Regular size and a Large size (that is comparible to the size of an office clipboard). The hot part of the pad/the part the spectators can write on and will be transmitted is the same size in both boards, so the standard board has more hot area than the large board (the larger size is to accomodate a legal pad of paper and look more like a off the shelf office clipboard.

What size is the Sensor Board?

The ThoughtCast Pro Sensor Board comes in 2 sizes: The Regular Size Board is 7 3/4" x 11 3/8" x 5/16" (19.5cm x 29cm x 8.5mm) and weighs approximately 17oz/480g. The Large Size Board is 8 7/8" x 12 5/8" (22.5cm x 32cm x 8.5mm) and weights approximately 22oz/630g.

How large is the hot part of the ThoughtCast Pro Sensor Board? And what does "hot part" mean?

Hot part is the area of the board where the impression will be captured...anything outside this area will not be captured. The hot part of all ThoughtCast Pro boards is approximatly 6" x 8" (15.24cm x 20.32cm)

How do I charge the ThoughtCast Pro Board?

Your board will come with a wireless charging disc and a piece of removable tape marking the location where the charger goes. Remove the tape and place the charger on that spot, and you're charging!

Pens and Markers

How many pens are included with the Sensor Board?

The ThoughtCast Sensor Board includes one gimmicked pen or marker (for whiteboard model). Additional pens, and more discreet/incognito pens, are also available in our store.

Can I use more than one pen/ring magnet at a time?

Although we have no idea why you would want to do this, the short answer is no. The sensor board was designed to be used with only a single gimmicked pen at a time.

What pens and markers can be used with ThoughtCast?

We sell a variety of pre-gimmicked pens and markers, including a regular pen, a regular barrel Sharpie, a king sized Sharpie, and whiteboard marker. Other pens and markers can also be gimmicked to work with ThoughtCast, just contact us with your pen choice and we'll see if it is compatible (and the cost to make custom gimmicked pens for you).

Installation and Setup

How do I install the app onto my device?

When you purchase a ThoughtCast system, you will receive a link to download the ThoughtCast software from the App Store on iOS or the Google Play store on Android. Once installed, use the username and password provided when you purchase a system or a software license to sign in and use ThoughtCast!

How many devices can I activate ThoughtCast on once I purchase it?

You can activate and use ThoughtCast with only one device at a time.

How many devices can I install ThoughtCast onto?

You can install ThoughtCast onto every device you own, but you can only use/activate one device at a time.

Does this work with my Android device?

Althought our current Android app supports a wide variety of Android devices running AndroidOS 7 (Nougat) and newer, as well as WearOS 2.0 and newer, we reccomend installing and running the app before purchase to make sure it installs and opens without crashing.

Can I turn off touch to peek and just have the drawing on all the time?

Yes! If you prefer to hide your device in your case and get your peek with a casual glance, this is achievable with the "Drawing Always Visible" switch in settings.

Can I change the thickness of the line?

Yes! There is a "Line Width" slider in settings.

Can you invert the color of the screen (so the drawing is a black line on a white background)?

Yes! There is an "Invert Colors" toggle in the Settings!

What version of iOS/Android is ThoughtCast compatible with?

Any iOS device iPhone 6 or newer, running iOS 10.2 or newer. We support all Apple Watches running WatchOS 2.0 or newer. On Android, we support select devices running Android 7.0 (Nougat) or newer, and select Android Wear devices running WearOS 2.0 or newer.

Is ThoughtCast Android Compatible?

Yes, we do have an Android app in the Google Play store and, althought it is functional, due to low adaption rates it is being phased out over the course of 2020. If you purchase ThoughtCast and use an Android phone, plan to either purchase an iPhone only for use with ThoughtCast, or email us about purchasing a iPhone from us at cost that is setup and ready to use.


What else do I need to perform with ThoughtCast?

When you purchase ThoughtCast, it comes complete with everything you need to get started performing. The only items we do not include is an iPhone or Android Phone to use as a receiver (as well as an Android Wear Watch or Apple Watch, you can use your own).

How does ThoughtCast Pro work?

The ThoughtCast sensor board contains an array of magnetic sensors, and the writing device contains a ring magnet. The magnetic sensors sense where the ring magnet is, and then show you the results on your iOS or Android device.

Can I ask a question not listed here?

Of course, just email hello@thoughtcastapp.com and we'll be more than happy to answer it for you! It might even make the FAQ too!

Does ThoughtCast come with any routines?

Yes! We have a secret page of routines that are only possible with ThoughtCast, and are only available to owners of a ThoughtCast system!

What happens if something goes wrong mid-performance?

Because this is a piece of electronics, and despite thoroughly testing it under every concievable instance and situation, there will still be times when one of two things go wrong: 1) the board becomes disconnected from the device, and 2) the pen strokes aren't being captured. When your board becomes disconnected, ThoughtCast will try to signal you in two ways. One, it will visually show you, via a small dot on the drawing mode and zone mode screen, that will change from green to red. Second, it will begin vibrating non-stop until the board reconnects. If the board is set up properly, every time the spectator touches the pen to the pad (in drawing mode), the device will emit a small vibration (if the device has a vibration motor). This is to alert you that a drawing is being made. If you know they are drawing, and the slate is connected, but the device isn't vibrating, you know there is something wrong and must revert to a backup peek method (center tear, etc). The only thing that could throw off the ThoughtCast Pro board is magnetic interferece, from a metal table or a spectators magnetic jewlery. If this happens, you can easily reset the magnetic sensors in the board using your phone or watch with a simple tap!

Can this be used with traditional impression pad techniques?

Yes, if you feel more safe and secure having a physical impression as well, you can use this with any number of impression methods, as long as that method does not rely upon magnets or involve metal that may interfere with a magnetic field.

What mobile phone device(s) can I use with ThoughtCast?

On iOS, ThoughtCast is officially compatible with the iPhone 6S and newer, running iOS 11 or newer. On Apple Watch, we support all versions of Apple Watch running WatchOS 2.0 or newer. ThoughtCast v1.5 will also be compatible with iPads as well that run iOS 11.
Although we have an Android app, due to poor adoption rates we are slowly phasing it out and focusing our efforts on iOS. On Android, ThoughtCast is supported by most Android Devices running Android 7.0 (Nougat) or newer. We support most Android Wear device running WearOS 2 and newer. Because the number of Android devices are vast and different, we have tested compatibility with Samsung Galaxy S7 and newer phones, Samsung Galaxy Note 7 and newer phones, and the Ticwatch E Wear Watch. However, if you are interested in using ThoughtCast on Android, download and run the app from the Google Play store first to make sure it runs and does not crash on your device before purchasing ThoughtCast. Because the Android app is no longer in development, our ability to troubleshoot issues and help provide support is limited.

Can I just use the drawing app that comes with the sensor board?

You could, but it wouldn't be easy! The app that comes with the sensor board is designed for artists, not magicians and mentalists. It will let you see what someone writes, but does not scale it up to see it easily, does not let you change the thickness of the line, does not let you save and send images with a single tap, and a host of other features our app was specifically designed to do. Our app is the reason we can provide this solution for mentalists and magicians at such an amazing price. Instead of reinventing the wheel, we found a unique piece of hardware that is readily available to the market, and designed an app to take advantage of all the amazing features of that hardware, cutting down on the cost of us to warehouse, ship, and repair hardware units when they break (and yes, your sensor board comes with a 2 year warranty no matter where you purchase it)!

How does this differ from other electronic impression devices on the market currently?

Previous to our product, there were two main impression technologies in use in the marketplace (neither of these are used in ThoughtCast currently, but to give you a idea to compare): Induction Coil: This is the technology where a induction coil and computer chip are inside of a pen, and when paired with a sensor board, it captures the drawing. This results in the absolute most reliable impressions. However, you're only able to use one specific pen with the impression pad, and the pen usually require a charge or battery like the sensor board, and are not only prone to breaking/able to break, they are expensive, usually costing $100 or more to replace. Plus, they don't look anything like a pen you would find off the shelf. Pressure Sensativity: This is a technology where the impression pad surface is able to register pressure sensativity. The benefit of this is you can use literally anything as your pen (you could even use your finger if you wanted to), but the problem is if the spectator does not press down hard enough, the impression might come through reliably. Plus, if your spectator holds the board on the "hot" part of the pad (the part that captures the impression), it will not capture what is being written with the marker or piece of chalk. Our solution is a hybrid of these benefits. By using a magnet ring, you get (almost) the same number of pen choices as a Pressure Sensative pad, but also (almost) the same level of reliability as the Induction Coil pad. We find this to be incredibly reliable, as well as incredibly nonchalant as the pens not only look absolutly normal, but you can use any pens you'd like that fit our magnetic rings.

Watch Mode

Is an Apple Watch app/Android Wear app available?

Yes! And, the watch app is included with all ThoughtCast purchases made starting in 2019!

What does the Watch App do?

The watch app simply shows everything you would normally see on the phone screen on your watch. It also shows you the battery power of your sensor board, the connection status, as well as the zone number of whatever zone is currently being drawn in.

Don't Take Our Word For It...

Magicians and mentalists worldwide have been putting ThoughtCast to the test, and the verdict is in!

I love the use of electronics in mentalism, so I usually purchase everything that is on the market to compare product features, and see what will work best for me in my act. ThoughtCast is one of those products that I will use nightly in my Las Vegas show. I will also use it for special appearances where pre-show information collection is required. The fact that I can use ThoughtCast on stage, with a King Size Sharpie to get real time information for a design duplication routine is great. Then, with a few settings changes in the app, I can use a standard pen to collect information pre-show. You can calibrate the ThoughtCast to work through almost any thickness pad. There is a little learning curve with the calibration and the app settings, but the only reason there is a learning curve is because there are so many features you can customize, depending on your performance needs. If you like using electronic collection devices, this should certainly be something to consider purchasing. It is well worth the investment.

— Gerry McCambridge, creator of The Mentalist and nightly performer in Las Vegas
