About this app
"Voice Range Checker" is an application to check your "voice range". When you talk into the microphone of iPhone/iPod touch, it can check "the highest voice" and "the lowest voice" in your voice. Let's get started by following the sample voice! You can send an email to your friends and post on Twitter about the result you checked. If you have any request or trouble report, post on Twitter with #checkvoicerange, or contact us at the inquiry form of CRI Middleware website.
