TOXIC+ is included and fully integrated.
ian's version of the classic TOXIC number force. It has been
designed to address all the issues that can be experienced using the
It can derive additional data like star signs, elements, birth day of the week and city information from your spectator's input so that the method can be removed from the reveal.
The keypad can be cleared by the spectator and equals can be pressed at anytime without affecting the outcome.
No other method has these features:
iPhone and iPad Connection
What you need: Two Apple devices
e.g. Two iPhones, or an iPhone and an iPad or two iPads.
Turn on BlueTooth and connect each device to the same WiFi network if available. If there is no WiFi or if they are on different WiFi networks then turn off the WiFi and just use BlueTooth. There is no need for an internet connection*.
Open the iTHUMP app on each device and it will automatically connect using Apple's Multipeer Connectivity. You will also be able to connect with other magicians who have iTHUMP on their phones, but only two devices at a time. (excluding your own Apple Watch)
The Multipeer connection status will be displayed on the top right of the screen. When connected the status indicator will change from red (not connected) to yellow (connecting) and then green (connected).
If the connection is interrupted it will attempt to reconnect automatically.
Note that the connection status indicator is only for the iPhone to iPhone connection and not for the iPhone to iWatch which is always connected.
*Internet connection is required if you want to lookup the city from the zip code or do the location or facebook force in TOXIC+
Transmit secret information
The idea of using a thumper is to transmit information secretly from an accomplice to you during magic performances.
You can place an iPad facing you at the front of the stage, put an iPhone in your pocket or between your belt and your body, place it in your close-up case or on your lap when seated at a table. Anywhere you can see the screen or feel the vibrations.
You can use a Bluetooth earpiece to hear the messages if looking at a device is not desireable.
It could be an inexpensive backup for your other electronic devices.
Sending Thumps (vibrations)
Press the "Thump/Send" button once for each thump. Make sure you leave a short gap between each press.
If you are sending multiple thumps, it will be more reliable to use one of the number keys 1-10 then Thump/Send. This method only sends a text message to the other device then device handles the vibration programmatically. The earpiece will speak the number sent as well.
By default the colours are preset and will "Thump" (vibrate 1-6) in Raindow order, though you can change the colour or order to suit your own preference: (Mnemonic: Roy G Bim)
You can customize the keypad to send any of these colours. (If you need to use other colours you could set up a custom message via the "MORE" button explained below.)
The Zenner Cards are preset to Thump (1-5) as follows:
Using the settings screen (click the + icon) in the tope right corner of iTHUMP to set the vibrations and change the key's to your own preference.
Press any of the preset keys to create a message then press "Thump/Send".
One off Messages
If you click in the text box at the top of the screen the keyboard will be displayed so you can type any one off message.
To hide the keyboard, press the "Hide keyboard" button. This will only show when the keyboard is active.
Remote Adhoc (one off) force number to TOXIC+
If you want to remotely send a force number to TOXIC+, preface the force number with a "#" hash symbol. e,g, #12345678
For this to work, the connection between iTHUMP and TOXIC+ must be established. (Green light). There will be no feedback on the device running TOXIC+.
If you click the "MORE" key the custom message list will be displayed. If you scroll to the bottom of the list and tap the "Add Item..." row, you will be able to enter your own items into the list.
These messages will be saved for future use.
To delete a row swipe left on the row then press "Delete".
To send one of these messages, click MORE, then tap the required message, then press "Thump/Send"
To hide the List click the "Hide Options" button.
Hiding the keypad (Blank Screen)
If using a device as a receiver only, you can hide the keypad by pressing the "Hide keypad" button so only the messages will appear on the screen of that device. The Assistant can then clear the screen if required by sending a blank "Thump".
To show the keypad again after hiding, click anywhere on the top 1/4 of the screen.
Stay on mode
You will want to make sure your iPhone or iPad do not turn off during your performance. (If only this was available for the Apple Watch)
In your iPhone or iPad settings:
iPhone and Apple Watch
What you need: An Apple Watch and it's paired iPhone.
The connection between the Apple Watch and it's Paired device is automatic when iThump is running on both devices. There is no "Status Indicator for this connection.
When the Apple Watch screen is turned on and the iThump or TOXIC+ screens are active you will be able to send or receive vibrations and messages between the Apple Watch and it's Paired device.
The Apple Watch has a battery saving restriction of only staying on for up to 70 seconds at a time. If the Apple Watch goes to sleep you will need to tap it's screen to reactivate it.
For optimal use set the following in your iPhone's Watch app:
