Horrible

It doesn't even open. I click the app and it just instantly closes. I got it as a joke but still. It should at least open.

WORST APP EVER

The worst app ever created. DO NOT BUY. I'm 20 years old and have excellent hearing however could only hear the "age 40+" it's total b.s. don't waste your money like I unfortunately did.

Very simple, does what it says :)

Nice little app that does exactly what it says, give you an estimate of your age governed by how high you can hear. Not really an age detector, just an interesting guide to how good your hearing is. Apparently at 28 I have the hearing of a 45 year old! this wouldn't surprise me, I do have inherently bad hearing for my age, lol. I like how simple the app is. No frills! Just the way I like it.
