The "Voice Meter Pro" app for the iPad, iPhone and iPod touch, is a simple, but effective app that helps children with autism spectrum disorders (ASD's), voice disorders, or any other child (or adult) monitor the volume of their own voice in a Fun and Engaging way.

Children with Asperger’s and other ASD’s often have difficulties producing the appropriate voice volume in different settings. Some children on the autism spectrum speak too quietly. Others speak too loudly. Still others do not compensate adequately for the social milieu or ambient noise level.

Understanding abstract concepts, such as the volume of one’s voice, can be difficult for children with ASD's. It’s well understood that adding a visual component to the otherwise abstract concept can often be very helpful for individuals with ASD.

OK so how does the app work?

Well….if a child is talking to quietly a blue background with a cartoon character struggling to hear is displayed. If a child is talking too loudly the background changes to red and the character puts it’s fingers in its ears. If the volume level is acceptable a green background with a smiling happy character is displayed.

• The on screen “volume thermometer” dynamically displays the volume level as it changes.

• There’s a "Sensitivity" slider so the adult can adjust the volume sensitivity to suit both the user and the setting.

• There’s also a "Dampening" slider. This helps to avoid the meter bouncing around in between words by introducing a slight delay before any movement is shown on the “volume thermometer.

• To give the user total control over the app the Upper and Lower limits of the "Green" (acceptable volume area) can now be adjusted by the user.

• For convenience the app works in both portrait and landscape modes on all the iPhone, iPod Touch and iPad.

We want to make this app the very best it can be and to this end we have included a feedback form inside the app for users to submit any issues or suggestions as to how it can be improved.

Why not download the app and give it a try?...... you might find it a very useful tool.

What’s New

Version 1.70

We fixed a bug where, if "Auto Lock" was set on your device, then the app would not override this when in use. Thanks to OrdinaryMum for the feedback. If you have any ideas how the app can be improved, or want to report a bug, please use the Feedback form in the App to let us know what you think, suggest new features, or to report any bugs. We do listen to users and your suggestion for a new feature could well be implemented in the next release.

Great for teaching vocal intensity control

I’ve used this app many times with the children I work with. I like the customization features that allow me to change sensitivity settings. The only change I would like to see added is a bell or vibrate feature when the meter is out of the green zone. Otherwise, great app!

Hi Blyn3D, Thanks so much for the positive review! It's great to hear the app works well for you. Thanks also for the suggestion, I will make a point of adding the feature in the next release. If you can think of any other ways in which the app could be improved, please feel free to use the contact form inside the app.

Needed serious adjustment

With sensitivity at 100% and dampening at 0%, I got it to work on my ipad pro 12.9. At default settings, I had to scream at the mic to even register.

Hi Harriska, Thanks for the 4 star review, despite the issue you are having with the sensitivity. Could you please email us at and we will be pleased to look at this for you. It could be that a particular device case or positioning of the iPad my be causing this issue. The default values should work well in most instances. Also, you have the option of using an external microphone with the app. Some users find this a useful (more flexible) option. Either way, please get in touch we will be happy to assist.

Updated review:
Fantastic app and development team! It was the first time I'd contacted support for an app and was so pleased with the quick response and genuine interest in my suggestion. The fact that my suggestion was actually incorporated it into an update is such a bonus...especially for my students:
I am beyond thrilled to report that T LOVED using her "green" voice this morning! She couldn't take her eyes off the meter and repeatedly stated "no blue - yes green" as we got further into today's activity.
Subsequent sessions yielded similar results: "T" is already beginning to generalize using her "green voice" in other school settings. The visual has been critical to her success. "I" is another student that now puts forth much more effort to increase his volume when using the app during therapy sessions. I highly recommend this app!!

Hi Csptx, Thanks so much for the positive comments and your contribution in helping to develop the app with your informed feedback. It has definitely helped get the app to where it is now. I hope it helps demonstrate to other users that we are very open to any suggestions regarding how the app can be improved. I hope it has benefited many more of your students since your review...and please keep in touch......... It's nice to be able to respond to reviews now (Good and Bad ones :-)) - thanks Apple!
