Ratings and reviews

It has one job and one job only and it works. It tells you left and right and that's what it's supposed to do that's all that goes on it does it very well. Edit update... I've been using this for a while and it still does what it's supposed to do without any hassle without any grief LOL. Like this developer says... It's simple and without any ads... It and a lot of confusion because a lot of earbuds and even full coverage headphones don't have a right or left indicator so this does the job well.

Simple, lightweight and efficient. Works great for my dollar store headphones. Note: I too was hearing "left" from each channel separately while playing music. Stopped the music and heard both left and right. I think this only happens when media is playing on certain devices or with certain apps (FM radio). App works flawlessly.

Couldn't possibly be any easier to use. Wear your headphones, launch the app, and touch anywhere on the screen. A voice will say "left, right" one time in the corresponding ear, while the other side remains silent. It also lights up a drawing of each side of a set of headphones while each tone plays. Touch the auto repeat button at the top of the screen to play each tone and light up each earbud in what is most likely an infinite loop. Easy to use and accurate.
