It’s incredible! It looks really cool. It’s brilliant. I really like it. I think it’s amazing. It’s gonna be one of the biggest things in magic this year.

Sean Heydon, Wizard Magic Review

Visual comedy magic

Hilarious, wacky, and magical the finger is under your full command so you can shorten or lengthen the routine to adjust to your audience reactions. Make it walk, wiggle, and jump out at your will. Or let it run on autopilot. Up to you! All on your spectator’s phone!

Soft or hard

Perform for ANY audience! The finger can stay on your hand! It doesn't have to detach if you or your audience don't like that; Many routines included that don't involve separated fingers, including the viral sensation where you pull out a low battery warning popup! You have full control over the trick's groseness level at any moment!

Easy and fun!

Super easy to use and highly versatile you’ll stun your audience with an ice-breaking visual gag or a full routine.

Anyone's phone!

Works on any borrowed smartphone and requires no apps, downloads, or pre-show preparations. Best of all it leaves no traces on your spectator’s phone. In fact, your spectator goes to Wikipedia themselves and that’s what the phone shows during and after the effect because KrazyFinger erases itself from the browser history.

Brilliant! I really like it. I’ve already filmed a video for my social media. You just borrow a spectator’s phone and go straight into it. There is no evidence how you did it.
