If you think $10 is too much money for an app, you won't even consider downloading anything on this list.
While Apple's App Store is full of great apps that are inexpensive or free, there are also a handful that cost hundreds of dollars.
For some apps, like electronic textbooks and professional tools, the cost is somewhat understandable. But for others, it's completely puzzling.
In total, you'd have to spend $12,949.80 if you wanted to buy all of the apps on this list.
$299.99 — Boffo Fun Time Game Pax 2
For a mere $299.99, you can download Boffo Fun Time Game Pax 2, which gives you access to four games including Clown Bop — a game that lets you punch a clown-like punching bag.
$299.99 — Perfect Penalty 2012
iTunes/ Alina Avdeeva
While some professional and educational apps may be worth their high price tags, others are just plain ripoffs. Judging by the customer reviews, that seems to be the case for Perfect Penalty 2012. It's a soccer video game that supposedly has the "most realistic graphics," but a review describes it as the "worst game ever."
$299.99 — Water Globe
Water Globe is just a set of interactive screen toys. You can play around with globes and make them snow, change gravity, and snowflake size. We're not sure why anyone would pay almost $300 for this app, when you can probably get a real snow globe for way cheaper.
$299.99 — TouchChat AAC with WordPower
This full-featured communication app is for people who have difficulty using their natural voice. Specifically, the app is for those who have autism, Down's Syndrome, ALS, apraxia, and other conditions that affect a person's ability to speak.

SafeSession Voice encryption is an app that lets you make secure VoIP calls over the internet. The company says your calls are protected by voice encryption algorithms. The person you're talking to also needs to have the app installed for you to have a secure conversation. Of course, there are dozens of VoIP apps out there that accomplish the same thing at a fraction of the price.
$349.99 — Barcelona vs Madrid
This game pits the huge rival soccer clubs against each other. The graphics look great, but we're not sure why this app is so expensive.
$349.99 — Mobile Cam Viewer
Mobile Cam Viewer lets you control and watch your live security and surveillance cameras. It supports several Webcam models, and multiple people can view the same camera at the same time.

$399.99 — iDIA - Diagnostic Imaging Atlas, Small Animal

$449.99 — The Alchemist SMS

$999.99 — Agro
Agro helps agronomists by taking the headache out of filing paperwork and keeping track of inspections, chemicals, crops, and pests on a farm. It seems pretty pricey for something that could probably be organized on a spreadsheet for free.
$999.99 — QSFFStats
QSFFStats lets you keep track of Flag Football stats for all passing leagues and is made specially for the company's website. Keeping track of flag football leagues has never been more ... expensive?
$999.99 — CyberTuner

$999.99 — app.Cash
app.Cash is a virtual cash register for the iPhone. There's little detail beyond the developer's short description in the iTunes Store, but it looks like it'll process transactions through to a printer to generate receipts. It's unclear why the app is so expensive — there are several free or less expensive point-of-sale apps in the App Store.
$999.99 - BarMax Bar Exam & MPRE Review
Though the BarMax Bar Exam & MPRE Review app itself is free, you'll have to pay up for all its features, which include feedback from people who have graded bar exams previously, lectures from Harvard Law School-educated professors, and more. It's a steal when you consider that BarBri, the company behind the app, typically offers this kind of bar exam prep for $3,000 to $4,000.
$999.99 - Ignition
LogMeIn's Ignition gives you remote access to your computer from your other devices, effectively letting you control your Mac or PC right form your phone. Or you can just download LogMeIn, which does the same thing, but for free.
