Toyota Yaris, standard audio
Treble dropped off sharply in this car. With mid at −5 and treble at +5 the score went from 55 to 65, confirmed by a check measurement. It sounded fuller and clearer, not harsh.

Put your iPhone on the headrest, let Tuno play a few test tones, and get the exact setting for your bass, mid and treble. In about ten minutes.

01
Place it upright against the driver’s headrest, right where your ears are. Tuno plays test tones through your car speakers via Bluetooth and records them.
02
You turn bass, mid and treble up a few steps, one at a time. Tuno hears exactly what those controls do in your car, with your interior.
03
Tuno works out the best setting, for example Bass 0, Mid −5, Treble +5, and checks it with one more measurement.
Two of our first test drives, with the real results from the app.

A premium system that was already tuned at the factory. Tuno says so honestly: everything at 0 is the best setting. Then you pay nothing.

You only pay when there is something to gain.
Measuring the same car again is always free.
With almost every car that has tone controls for bass and treble, or bass, mid and treble, and Bluetooth audio. Equalizers with five or more bands will follow later.
With CarPlay, an iPhone can’t play sound to the car and record with its own microphone at the same time. So you measure once via Bluetooth. Afterwards you can use CarPlay as usual; the settings in your car stay as they are.
An iPhone with a recent version of iOS. Every iPhone microphone hears slightly differently; Tuno takes that into account.
Yes, during each measurement for about 20 seconds. Tuno counts down, tells you when to get out, and plays a sound when you can get back in.
Nothing leaves your phone. The test tones are analysed on your iPhone itself. Tuno has no account and no server.
