Product & app
What you will practice with.
What is the INNVOX smart vocal trainer?
INNVOX is an app-connected vocal trainer based on the SOVT principle used in vocal straw exercises. The device provides adjustable resistance; the app adds daily plans, guided exercises, baseline records, and session feedback. Explore the product.
How is it designed to help my singing?
It gives you a structured way to practice breath control, pitch and consistency before you sing. With the right technique, you may notice that you can speak more loudly with less effort.
How many resistance settings are there?
There are five settings, numbered 0, 1, 2, 3 and 4. Choose a comfortable setting and follow the supplied instructions.
What does the app show?
Your daily plan, guided exercises and a session review. The example screens show baseline records, pitch steps, a set counter and before-and-after readings. See the app screens.
Are the percentages on the screen guaranteed results?
No. The screens are interface previews; their readings illustrate the app layout. They are not evidence of typical improvement or a promise of what any individual will achieve.
Which phones will be supported?
Compatible phones, operating systems and connection requirements will be confirmed with the product offer before you purchase the device.
Do I need an app subscription?
Core app features are included with your INNVOX device purchase, with no additional subscription fee. These cover device connection, basic warm-ups, on-screen guidance, practice records and before-and-after comparisons. Device-connected features require the smart trainer and a compatible phone.
Can I try the app before my device arrives?
Yes. You can try the app before your device arrives. Features that require a device connection will be available once you connect your INNVOX trainer.
You can keep using the standalone app features after testing ends or if you cancel your reservation. Trying the app does not affect your right to a full refund before shipping. App access details

What does the $5 reservation cover?
