Ridiculously Expensive Apps Actually Sold On The App Store

Not to be outdone by the medical community, some of the most high-cost apps out there are designed for those who work on musical instruments. While tuning a piano has historically required the skills of a specially trained expert, the task can now be augmented with technological assistance from the Verituner app.

Certainly, properly tuning a piano or any other instrument still requires a great degree of skill, but Verituner promises improved results. As you’re tuning, the app measures each note and builds a custom tuning picture for each individual instrument. Verituner costs $599.99, but considering the cost of professional tuning services — which can reach up to and over $200, according to Bankrate — a professional tuner could make back their investment relatively quickly.

In addition to standard tuning, Verituner also offers more than 90 historical temperaments, allowing you to tune a piano in such a way that it could more accurately play classical music from previous musical eras (via Piano Tuners).

The market for such an app might be small, as evidenced by the fact that it only has ten reviews, but all of them give it a glowing score, suggesting that Verituner strikes the right chord with its users.
