There are some applications that I am looking forward to feeding to my iPhone from Apple's (NASDAQ:AAPL) App Store this year.

There's the Chipotle Mexican Grill (NYSE:CMG) (NYSE:CMG-B) mobile ordering program that came and went in January. A bug-free version was supposed to be out already.  And Sirius XM Radio (NASDAQ:SIRI) will finally release an in-house app to stream Sirius and XM Web radio streams this quarter.

It is only if I had to work my way all to the bottom of that ranked list that I would run into LeapFrog Enterprises' (NYSE:LF) Number Rumble math game.

Yes, the same LeapFrog that rocked toddlers in the earlier half of this decade with its LeapPad educational toys made its App Store debut last week. The Leapfrog app is billed as "the first of several planned LeapFrog iPhone learning games." Let's stop right there for a quick poll.

How many kids -- between the game's target age range of 6 to 10 -- have their own iPhones? Not many, I'm sure. So how many parents want to hand over their smartphones to their children so they can "shake, tap and spin their way to math equation expertise" tonight? Not many, I'm sure.

Thankfully, despite being called a "LeapFrog iPhone" game, it's also perfectly playable on high-end iPod touch devices. There are probably more kids that own that, free of monthly AT&T (NYSE:T) data plans, but it's hardly a toddler trinket. The exposed iPod touch screen that scratches so easily isn't exactly marketed as a gizmo for early learning.

The game is reasonably priced at just $2.99, but it's also competing against hungrier developers who are putting out free ad-based learning titles to get their feet in the proverbial door. In short, it's no surprise to see just six user reviews for LeapFrog's App Store debut.

As the App Store gets more crowded -- as tens of thousands of programs ultimately become hundreds of thousands -- it will get harder to stand out in a crowd. Is it even worth the hassle for a major toy manufacturer to spend serious coin in a program that won't be a material contributor?

Financially speaking, it's probably hard to justify. However, since the iPhone is so hot these days, it makes sense from a publicity standpoint to appear to be catering to the growing audience of iPhone and iPod touch owners.

Yes, I'm calling Number Rumble more of a publicity stunt than a legitimate moneymaker. You can "shake, tap and spin" me around, and I'll still feel that way. Investors love seeing their companies tied to successful names like Apple, but the financial reality will be a rude awakening.
