That said, there’s no doubt Apple is always working hard to make the review process more transparent, seamless, and developer-friendly. And while some slip-ups are inevitable, it still somewhat mind-boggling that Apple’s App Store gatekeepers will often let in apps that are downright scammy and designed to bilk non-suspecting users out of their hard-earned money.

It’s certainly something of a cat-and-mouse game and Apple, to its credit, will often take swift action once a scam app is brought to its attention. Still, there’s no denying that Apple still has quite a bit of work to do when it comes to preventing scam apps from populating the App Store in the first place.

The latest instance of a scam app making its way into the App Store involves a fraudulent heart rate app which targets iPhone users with Touch ID enabled devices. Brought to light via 9to5Mac, the app is called Pulse Heartbeat and claims to measure a user’s heartbeat when a finger is placed upon the Touch ID sensor.

The con works as follows:

What the app does is ask users to place their finger on the Home button, supposedly to take a heart-beat reading. In reality, the app dims the display brightness its minimum to hide the content — which is actually Apple’s dialogue requesting authorization for a recurring in-app purchase.

The in-app purchase charges users about $85 for an annual subscription, with an option for a monthly subscription as well. A user on Twitter even managed to capture an online ad the app makers are currently running:

If you go to the app’s download page, you’ll see a number of less than favorable reviews calling it a fraud. Apple will hopefully remove the app sooner rather than later.
