## WikiTest Description
WikiTest is a modern book test that uses a borrowed smartphone.

“Marc's apps are unbelievable.”
—David Blaine

“The greatest app for magicians. It's incredible.”
—Asi Wind

- You ask a spectator to search for ANY object, person or place on Wikipedia on THEIR phone to bring up its article.
- Whilst you look away, the spectator scrolls through the article and thinks of a random word on the page.
- You then tell the spectator EXACTLY what object they're looking at, as well as what word they're merely thinking of on the page!

The text (and of course their phone) can be thoroughly inspected after the routine with NOTHING to find!

* Works with ANY borrowed modern smartphone, tablet or computer.
* You NEVER touch their phone!
* VERY easy to perform.
* NO accomplice required.
* NO memory work needed.
* Works in English, French, German, Spanish, Dutch, Italian, Swedish, Brazilian Portuguese, Norwegian, Danish, Japanese, and Bahasa Indonesian with more languages added regularly.

No other devices are needed to perform the effect (you only need your iPhone!)
However, if you have one, WikiTest comes with a fully functional Apple Watch app. It also supports popular devices such as the PeekSmith and Oblivious Notifier.

*** WikiTest was voted "Magic Trick Of The Year", and was performed on the TV special "Beyond Magic".

WikiTest also integrates with many other apps, such as Earworm and Diverter!


WikiTest also has an optional Pro Tools package, giving:

- Live Peek - see what is being typed in real-time
- Image Peek - peek the article's image
- Auto Translate - automatically translate all searches in any language to your native language
- AutoPair - pair with your spectator automatically
- Real Main Page - use the real main page in performance
- QuickLink - pair immediately with a fast pairing method
- Article Extract - see a short article extract from the searched article on both the Peek Screen and the Apple Watch app
- NFC Support
- Further app integrations

...and much, much more!

## WikiTest Reviews in United States

### ***** "FANTASTIC"
Mark has thought of everything and continues to add new ideas and updates. This is my go to carry trick. 20/10
-- Skeus, 2025-05-06

### ***** "Great for magicians novice to expert!"
This is a FANTASTIC effect that will blow minds with incredible simplicity. Marc is the man!
-- TheRealPilotAlex, 2025-05-06

### ***** "A nuclear bomb of magic"
This is BY FAR the most effective weapon in my magic arsenal, and it’s on me all the time, ready to go at a moments notice. Without question has given the strongest reactions. Well worth the price!
-- Sp1ice, 2025-04-30

### ***** "Incredible"
One of the best magic effects out there. And what’s even more amazing than that is the support and reliability of the creator, Marc Kerstein!
-- Jdjdjsnsj, 2025-04-30

### ***** "Amazing"
One of the best apps I own. Everything is a layer of deception.
-- show no us, 2024-03-06

### **--- "Why does the calculator look terrible"
It seems like the base app input methods are designed to be disappointing to force us to upgrade. The calculator input looks like a fake app, not the built-in iPhone calculator. This is such an easy fix and it’s disappointing that it’s not fixed on such an expensive app. Otherwise this is a perfect trick that could only be improved by video instructions.
-- That one clown, 2024-02-09

### **--- "Google evolved and makes the process much more cumbersome"
Unfortunately the google search brings the count of articles and other metrics immediately on screen. There is no need to click on a link anymore. What a pity!!!
-- twainton, 2023-12-13

### ***** "The GOAT"
Greatest marketed magic trick of all time. Hands down.
-- Bryan Sanders (@MAGICisBS), 2023-02-15

### ***** "Brilliant"
WikiTest is the gift that keeps on giving, or at least the app that keeps on giving. The redesigned app looks fantastic and is more customizable now with the ability to set up presets. It’s absolutely amazing that Mark continues to improve upon WikiTest when it was nearly perfect from the beginning. Great work!!
-- B4UC2Far, 2022-10-13

### ***** "Marc, amazing costumer support"
Marc is absolutely incredible. He helped me when I forgot my password and contacted me in the first 30 minutes. He is great!
-- Emilio. M, 2021-12-18

### ***** "Outstanding!!!"
Perhaps the greatest mentalist app available. Just buy it and thank me later.
-- batman_1961, 2021-09-25

### ***** "Unlike anything on the market"
WikiTest is incredible. I know it’s a little pricey but trust me when I say you will not be disappointed. You are paying for some pretty advanced technology to make this possible. Well done Marc!
-- Popcornaidan, 2021-09-17

### ***** "Amazing App"
This works very well, and astounds people.  It combines several levels of deception.  You can discern a chosen word which the volunteer only thinks, never writes down nor speaks.  Its amazing.  Not too difficult to perform.
-- David der German, 2019-06-16

### ***** "Simply the BEST..."
The only thing holding this back is technology. This app is always by my side.
-- Scott Xavier, 2019-06-08

### ***** "Best Magic App ever!"
This is an amazing tool for any magician. It’s best app I have ever owned so far. Mark Keirstien is a beast, his customer service is in matched. He puts lots of work and thought into all his apps and keeps them updated and fine tuned. Just when you think it can’t get any better, Mark releases a new update and blows our minds.
-- MagicofElder, 2019-01-25

### ***** "So good."
Arguably one of the best magic phone apps out there today. So good and flawless.
-- musicmanamc, 2019-01-17

### ***** "Best magic app ever!"
This is a game changer that could make people think you have real mentalism power. This is work with any device with internet connection. I cannot believe how Marc could make this app. Thank you very much! Best purchase I have ever made!
-- Wooooo Traaaaaa, 2018-08-26

### ***** "Just bought it, love it!"
I’m here at the 2018 Magic Live. Two of my friends just suggested this app to me. I bought it, tried it, loved it. Worth the money :)
-- Henry TTW, 2018-08-06

### ***** "Genius"
All I can say is, “wow.” Absolutely genius from top to bottom. You can tell no punches were pulled in the development of this god-like app. I never thought I’d buy a magic app, let alone one that’s so expensive, but there’s a reason it is. I honestly wish it cost more because it’s just that good. This is now my closest guarded magical secret.
-- JimmyXZoSoXPage, 2018-07-12

### ***** "WikiTest is the best!!"
There are a lot of magic apps on the market....but this one is by far the best. The reactions you get are insane! One of the best magic purchases I've ever made.
-- Joshuaahart, 2018-07-10
