- "Real-time" voice changing technology
- Record your voice
- Retina graphics for iPhone 4

- Recordings sync back to iTunes
(Requires iOS 3.2 or higher)
- Email your recordings to your friends

- The definitive accessory during Halloween and other dress-up events!

NOTE: iOS restricts when the application can run with other audio applications, so you CANNOT use Devil Voice while running other audio apps, like listening to music or during phone conversations, etc.

Suggested accessory for making your voice heard by "EVERYONE" in a 350 foot radius:
Pick-up a portable mini-amp (such as a $20 HoneyTone amp) and your devilish voice will boom across your entire street! Seriously awesome for camping and telling stories!

We realize that the real-time playback nature of Devil Voice is a new experience for many users, so in response to user requests, we are working on adding a "Talk-Back" mode to Devil Voice for compatibility with built-in speakers.

In the meantime, please use headphones or external speakers for best results! Regretfully, it is the laws of physics that when a microphone can hear the speaker well enough, it will cause a feedback loop. This is why output from the device's external speakers doesn't work so well on small devices like iPods and iPhones. (We have no way of physically changing the distance of the microphone from the speakers in the iPhone or iPod touch.) Also, don't forget that you can turn the "mic boost" all the way down if you only want to hear the playback by itself.

In addition, we have our voice changing system actively running at ALL TIMES when using Devil Voice. This allows a person to record audio and then additionally talk at the same time when playing back a recording. It's a very cool 2 track-ish kind of feature. If we disabled the "active voice changing system" when touching the play button (and had the audio be output to the device's speakers), it will have limited this fun "2 track" feature of the app. However, as mentioned above, we are working to add a "Talk-Back" mode for those who specifically want speaker playback.

The ultimate voice changer


The ultimate in voice changing apps! I found this app by chance thanks to google because it doesn't really search well with voice changing or anything close. We are having an awesome drama this Sunday at church. Thanks to irig and an iPad this will be one of our main characters, the devil. Running this thru our sound board and an headset mic and our devil will send absolute chills down your spine. Thank you for a great and simple affordable app!

Mildly Fun, But Not Functional


It'd be great if this app could actually be shared with the person sitting next to you. If the app is installed and your phone happens to be in "ear receiver" mode only and not on the "speaker" setting (either from voicemail or form another app, the app is stuck that way irreversibly. Maddeningly, it even reminds you to turn your speakers on while using the app, while it doesn't actually give you a choice to do that within the app!!

This isn't actually an effect but rather a pitch shifter anyway. There are many more apps out there that let you change the pitch of your voice and are more functional than this one. Overall, this was disappointing.

Awesome app minus one big issue


Great hilarious app however on my phone it won't let me record or change the voice at all the screen pulls up and not one button works so it's stuck luckily on the demon voice which is pretty great but again wish I could use the whole app.

Also would be cool if they made it so you could use it when you call someone just an idea.
