This effect requires so much fiddling if you are using an Android and don't have Safari....a
terrible app in and of itself. The app for Boarding Pass, once you finally get it on your phone, is
unwieldy and your phone "stalls" and needs to be restarted each time you use it. Not practical at
all. You'll notice in the video, that Mariano uses a separate phone than his regular phone (red vs
black) while performing the effect, most likely because he too finds this cell phone stalling issue
a pita.....That makes it weird for the spectator. There's too much "fishing and fiddling" while you
secretly type in their stated destination...the ruse is just not believable I won't be using this
product.
Did you reach out to the creator via his website: https://marianogoni.com? I use an iPhone so I can't speak to issues with Android, but it could be that you can get effective troubleshooting just by asking. The performance quality with iPhone has been 100% for me, so perhaps there is support you can receive to cause your platform to work properly. As to the "fishing and fiddling" there is a way to openly apply the needed information right in front of participants, and it will not arouse suspicions. I wish I could tell you exactly how but doing so in a public forum would reveal part of the effect's secret to others who have not yet purchased it. Here again, I think if you asked for support from the creator you might get a few helpful presentation tips. One final suggestion: there is a FACEBOOK user's page that has helpful tips for using this app. If you join you'll see my name as a member. Feel free to direct message me and I can tell you in private exactly how I do the presentation to avoid any fiddling about. Hope this helps.
