Inertia Pro is a completely new forcing app that relies on a diabolical new principle. Inertia Pro lets you force *anything* on *any website*... whilst the spectator is looking at the phone. It’s built in to a web browser, allowing you to use it to force pretty much anything, such as: • An Instagram photo or video on ANY profile. • A specific item for sale on eBay. • Any Netflix movie. • A product from Amazon. • A line of text or single word on a news website. • Any photo from Google Images. • ...and so much more! (Note: The page used is completely genuine - this will work on ANY website the spectator chooses, and in ANY language!) “Marc is without doubt the single greatest mentalism app creator I know. From design to execution, his apps are absolutely flawless. Inertia Pro is a prime example of why I trust in his work so implicitly, it is jaw droppingly good and represents one of the most cutting-edge mentalism releases to date!” - Michael Murray Plus, with Inertia Pro's new Edit Mode (paid feature), you can now edit the text on any site to ensure your force is included. ALSO - Inertia Pro: Momentum (paid feature) now also lets you use Inertia Pro on a borrowed phone. With multiple pairing methods available and a redirect process, Momentum is an extra purchase within Inertia Pro that will let you perform the same effect using a borrowed phone. Furthermore: WikiTest Pro Tools users can even use further integrations between Inertia Pro: Momentum. If you have Xeno, you can use your own Xeno Sites with Inertia Pro, or use any of the public Xeno Sites available in the gallery. And... you can perform Inertia Pro with any Xeno Site remotely! This can all happen on the spectator's device, without you touching it. Perfect for Zoom shows or long-distance performances! The Jerx wrote this about Inertia Pro: “You know those phone forces where you would hold the phone upside down and have them scroll blindly and whatever picture or item they landed on would be forced (usually because their scrolling wasn’t doing anything)? Well, this app allows you to do that type of force face-up while the spectator looks at the phone. It’s so good and *feels* exactly like it should.” - Andy @ The Jerx --- Inertia Pro is for entertainment purposes only, designed for professional performers. This app does not provide true mind reading abilities or anything similar. Please get in touch to discuss TV or video performance rights.

NAMEFORGE - MODERN MENTALISM, FORGED TO PERFECTION Created by professional mentalist Paul Brook, NameForge is a cutting-edge mentalism tool that transforms a simple word into a powerful, personalised moment of mentalism. Take a name - typed, spoken*, or selected - and instantly generate a compelling acrostic, where the first letter of each line spells out the original word. It feels deeply personal to your participant, yet the method remains entirely invisible. Whether you’re performing on stage, close-up, or over video, NameForge delivers genuine impact - without giving away your secrets. CUSTOMISED INPUT AND OUTPUT, SEAMLESS DELIVERY Any word can be inputted into NameForge, which will then be turned into an acrostic - where the first letter of each word creates another word. After the acrostic is made, it can then be sent virtually anywhere you want, via the predefined outputs, or use the customisable outputs to send to somewhere specific. PRO FEATURES FOR WORKING PERFORMERS Enhance your routines with optional Pro features (In-App Purchases): • Apple Watch Peek – discreet reveals on your wrist • Voice Input – speak the word aloud to create the acrostic • Camera Input – show a written word to any of your phone's cameras to input it • Unforged Sending – send unformatted words to any integration • Search Result Output – make their phone show your prediction • Add More API Outputs – connect to more integrations COMMUNITY-DRIVEN SHARING Profiles and word lists can be shared between performers with ease, letting you explore and perform community-favourite routines in seconds. CONSTANTLY EVOLVING NameForge is packed with tools and always evolving - ready to help you create miracles, anywhere, anytime. *Voice Input requires the ‘Voice Input’ In-App purchase.

Inertia Pro costs $69.99 and NameForge $69.99 up front. Inertia Pro sells 2 one-off in-app purchases and NameForge sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Inertia Pro holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Inertia Pro has 30 ratings behind it against 4, so its average is the more settled of the two.

Inertia Pro ships an update weekly, NameForge every 8 days. The most recent releases landed on October 9, 2026 and September 22, 2026 respectively.
