Not great

The visuals are not accurate. The moving dot does not hit the targets on the screen accurately, even when I’m producing the sound perfectly and clearly. Please update it so the dot hits the vowels. Sometimes the R shows on target…sometimes it doesn’t. The idea behind this app is fantastic!! But this app doesn’t work as advertised.

It’s not perfect, but it’s really good,

I use VowelViz often with my students who struggle with vocalic /r/. It provides them with reliable visual feedback for their production, helping them develop independent self-monitoring , which is always a struggle. Some voices don’t register as precisely as they might (for example, it doesn’t recognize my /i/ accurately, but does catch everything else I say correctly), but there is nothing else out there that does what this app does. For the pediatric SLP, it’s the best thing going!

Too expensive

I bought this for $50 hoping it would be a big help for my kids working on vocalic /r/ as I’m a speech path. It wasn’t helpful.

Free app and still 2stars

For a free app, this program is still not a solid value. Buggy, frustrating and poor UI all equal a rough overall experience. I heard people paid $29-$49 for this? Yikes, I would have felt ripped off.
