Many people aren't willing to spend more than a buck or two on a premium iOS app — but believe it or not, some of the most expensive apps that have ever been released have cost hundreds to over $1,000. While several expensive apps have either been abandoned or taken offline over the years, you can still find many available at their staggering prices if you look hard enough. Lifewire / Miguel Co Here are some of the most expensive apps that you can currently buy from the iTunes App Store.

A Location-Based Luxury Lifestyle App: VIP Black for $999.99 VIP Black is a premium app geared toward millionaires (and perhaps even billionaires) who want to discover and enjoy the most luxurious events and services around them. Similar to how you might use a regular location-based app like Yelp or Foursquare, YIP Black uses your location to find the highest quality art/literature, bars, clubs, butlers, cars, cinemas, events, and experiences near you. Through partnerships with participating venues, members receive special VIP treatment at their event or venue of choice, including things like complimentary upgrades, gifts, priority access, welcome packages and more. Concierge teams are also available so that anything and everything can be outsourced — from getting the dry cleaning done, to booking a private jet. The app claims to update its partners and partner privileges regularly, however, it hasn't seen an update since May of 2017. Despite remaining online in the App Store, it's unclear if the VIP Black app has been abandoned. Download VIP Black for iOS

The Most Advanced Piano Tuning App: CyberTuner for $999.99 CyberTuner is a professional piano tuning app that will cost you more than what many average to good electronic keyboards cost. This app has been in development for years, including one year of vigorous testing by music experts around the world. Designed for professional tuners who already know the basics and own their own equipment, the CyberTuner app combines functions programmed by a Registered Piano Technician with an intuitive layout. Technicians have the freedom and flexibility to use the app to tune pianos exactly the way they want with incredible accuracy. The CyberTuner app is updated regularly for the latest iOS versions and newest devices along with both new and enhanced features added to it every so often. As if the price didn't shock you enough already, users of the app will need to pay another $79.99 every year for CyberCare to get the upgrades. Download CyberTuner for iOS

A Specialized Payment App for Cashiers: app.Cash for $999.99 app.Cash claims to be a "stylish cashier system for all purposes." The app is designed to replace the traditional cash register to create sales transactions and receive payments. It even works offline. Although the app can be used by practically any business that needs to collect customer data and take payments, it appears to be specifically tailored for restaurants so that servers can conveniently use a mobile device directly at customers' tables. Menu buttons are available and categorized by food and beverage types so that servers can input customers' orders directly into the app. A graphic representation of the tables can also be created and viewed to keep tracking of table numbers and their orders. The app supports two printer models and must be updated by contacting the developer directly. It's one of the most expensive apps in the App Store at nearly $1,000, however, it claims to be cheaper than a traditional cash register system, making it perhaps an attractive option for some businesses.
