The maker of the immensely popular iStethoscope Free iPhone app has warned that the app might become temporarily available for download from the iTunes App Store as it struggles with the high demand.
According to Web User, computer scientist Peter J Bentley, who developed the app, warned that the iStethoscope might be temporarily unavailable and prompted users to go for the paid version of the app - which costs 59p - if this happens.
He wrote on the application's official website that “Because of the massive demand iStethoscope Free may be temporarily unavailable from the App Store. If this happens and you wish to try the app please check out iStethoscope Pro. Thanks for your patience!”
The iStethoscope Free iPhone app, which has been downloaded around three million since it launched, allows iPhone and iPod Touch users to listen to their heartbeat and see a heart waveform chart.
The app works by placing the iPhone on the bare chest and use of good headphones have been recommended for sound quality. In order to get the waveform chart, users need to shake the iPhone.
