About
Inertia Pro is a cutting-edge mentalism and magic performance app for iOS, designed by acclaimed app creator Marc Kerstein. At its core, it employs a novel forcing principle embedded inside a fully functional web browser, allowing the performer to steer a spectator to a pre-determined result on virtually any live website — including Instagram, eBay, Amazon, Netflix, Google Images, and news sites — all while the spectator is actively looking at the screen. The app works in any language and on any website the spectator freely chooses, making the experience feel completely organic and genuine. Inertia Pro's Edit Mode (a paid add-on) lets performers modify on-screen text to ensure a precise force is possible, broadening creative possibilities for unique presentations. The Momentum add-on takes the concept even further by enabling performers to use Inertia Pro on a borrowed phone via multiple pairing methods and a redirect process — ideal for parlor shows, street magic, and Zoom or remote performances. Additionally, Inertia Pro integrates with the Xeno ecosystem, allowing performers to use their own Xeno Sites or publicly available gallery sites, even triggered remotely without touching the spectator's device. Designed exclusively for professional performers, Inertia Pro is rated 4.9 out of 5 stars and is praised by top mentalists worldwide as one of the most innovative releases in modern mentalism. The app is for entertainment purposes only and does not provide genuine mind-reading capabilities.
Key Features
- Force Anything on Any Website: Using a novel embedded principle inside a real web browser, performers can steer spectators to a predetermined result on any live site — Instagram, Amazon, eBay, Netflix, Google Images, and more.
- Edit Mode: A paid add-on that lets performers modify text directly on any website, ensuring a precise force is always achievable regardless of the page's content.
- Momentum — Borrowed Phone Support: An in-app purchase that enables Inertia Pro to work on a spectator's own phone via multiple pairing methods and a redirect process, eliminating the need to hand over your own device.
- Remote & Zoom Performance Support: Momentum enables remote performances where the entire effect can happen on the spectator's device without the performer touching it — perfect for online shows and Zoom performances.
- Xeno Ecosystem Integration: Inertia Pro integrates seamlessly with Xeno, letting performers use custom or public Xeno Sites and even trigger forces remotely on the spectator's device.
Use Cases
- A stage mentalist forces a spectator to land on a specific Instagram post on a profile they freely choose, creating a seemingly impossible mind-reading effect.
- A close-up performer uses Edit Mode to ensure a specific word appears in a news article, then has a spectator discover it organically during a book-test style routine.
- A Zoom performer uses Momentum to direct a remote audience member to find a forced Amazon product on their own phone without any physical contact.
- A professional entertainer integrates Xeno Sites with Inertia Pro to create a fully remote, hands-free forcing experience for corporate virtual events.
- A mentalist uses the borrowed-phone feature at a walk-around event, borrowing a guest's phone to demonstrate an apparent ability to predict their online choices.
Pros
- Works on Any Website in Any Language: The app uses a genuine browser experience, so spectators interact with real, unmodified websites — making detection virtually impossible and performances feel completely natural.
- Highly Praised by Top Professionals: Rated 4.9/5 stars and endorsed by respected figures in the mentalism community such as Michael Murray and The Jerx, cementing its reputation as a top-tier professional tool.
- Versatile Performance Modes: From in-person close-up shows to Zoom performances and borrowed-phone routines, Inertia Pro adapts to a wide range of performance contexts.
Cons
- High Base Price Plus Additional In-App Purchases: At $69.99 with Edit Mode and Momentum sold separately, the full feature set can become expensive, which may be a barrier for hobbyists or beginners.
- Requires Practice and Skill: Like most professional mentalism tools, Inertia Pro demands a learning curve and rehearsal time before it can be effectively deployed in live performances.
- Niche Audience: The app is purpose-built for magicians and mentalists — it has little to no utility outside of professional entertainment performance contexts.
Frequently Asked Questions
What does 'forcing' mean in the context of Inertia Pro?
In magic and mentalism, 'forcing' means secretly guiding someone to a predetermined outcome while making them feel they made a free choice. Inertia Pro does this by controlling what a spectator lands on within a real, live website.
Does it work on any website?
Yes. Inertia Pro is built into a web browser and works on virtually any website — including Instagram, eBay, Amazon, Netflix, news sites, Google Images, and more — in any language.
What is Momentum and do I need it?
Momentum is a paid in-app purchase that allows you to use Inertia Pro on a borrowed spectator phone rather than your own. It's ideal for performers who want a more hands-off, convincing experience or who perform remotely.
Can I use Inertia Pro for Zoom or online shows?
Yes. With the Momentum add-on, the entire effect can be performed on the spectator's device without the performer touching it, making it suitable for Zoom performances and long-distance shows.
What is the Xeno integration?
Xeno is a separate mentalism platform. Inertia Pro integrates with it, allowing performers to use their own custom Xeno Sites or browse publicly available Xeno Sites in the gallery, and even trigger Inertia Pro forces remotely on a spectator's device.
