There are lots of photo prediction apps out there (including one of mine, "101 Deck") where you say "earlier today I took a photo…" and you display a photo you supposedly took at some time in the past. Good stuff, but what if you could take a prediction photo right then and there, with the spectator actually in the photo? Well, now you can!

Here's the basic idea: Begin by saying "I'm going to have you pick a card, but first I want to pick a card myself…" You take a card out of the deck, keep it hidden to the spectator, hold it up for the camera and snap a photo (with the spectator in the photo as well). Phone goes down on the table, cards get shuffled up. From here you do whatever card routine you like. At some point the spectator chooses a card. You vanish it, it reappears, vanished again. Everyone is immensely impressed and you start to walk away. "Oh wait, remember that photo I took before we even began?" You open up your photo album… "I knew you were going to pick that card." And there in your album is the photo you took, clearly showing you holding the chosen card with the spectator in the photo as well. Thus proving without a doubt you made an impossible prediction.

A few disclaimers before I keep going: First, this trick requires a gaff card. Probably the most common gaff card out there, you most likely have it already, and after reading this sentence I bet you know what it is. Second, this app uses an enormous amount of processing power, and thus the newer/faster your phone is the better. It works great on the 5, pretty good on the 4S, and not so great on the 4 (I'd personally not recommend this app if you have an iPhone 4). It's not available if you have a 3Gs or earlier. It would most likely melt the processor anyway.

Third, this is not the type of app that "just works." iPredict "just works." Every time you make that call you know what you're going to get and you know it's going to work, and there's no chance some kid is going to pick up and go "Hello?" It works the same way day in and day out and you don't need to do anything different as you move around the room. This app relies on the camera, and so different lighting conditions have an impact on how you need to use the app to get a good result. If you follow the steps I give to take the photo, you'll end up with a good result 98.479% of the time. You'll need to experiment a little and learn how to help the app take a photo that will give you a good result (just doing a quick test photo/setup every time you move will help). If you understand how the app works you won't have any trouble.

Ok back to the magic. There's lots of possibilities on how to use this. Perhaps a reverse mind reading. Pick a card, take a photo, and have the spectator read your mind and tell you which card you picked. Since you have photo proof, you can't be accused of switching the card!

Another idea to leave a lasting impressing: Take the photo, do your thing, then at the end say "remember that photo? I knew what card you were going to choose. I'll post it to my facebook page, go have a look if you want." You can post to facebook, twitter, email it or SMS exactly the same way you would any other photo in your album (you hit the "share" button). Do this to get some likes on your page, or if you email them the photo they will have your contact details.

- This app does include what we call "Confederate Mode." If you have a friend that also has a phone and a copy of the app, you can take the photo and your buddy can make the secret entry on his phone, which will then be sent over to yours. So this means you can take the photo, hand your iPhone to the spectator, then at the end of the routine have the spectator open up the photo album herself. You never have to touch the phone!

- You can end "clean" if you choose, meaning the image will be in your real camera roll and so at the reveal you won't be in the app anymore. If the spectator starts snooping around there won't be anything fishy.

- A "stealth app" in every way possible. Your spectators will never know an app was involved. Everything they see looks "normal."
