Do not download if you are prone to forgetting to cancel free trials. I signed up and forgot to cancel and instead of a monthly charge which would be no big deal, they make sure to charge you for an entire year to prey on anyone who forgets since Google won't overturn a charge even if it's second after the payment processes. I've had this for 3 months now and have used it once, during the free trial. The apps okay but manipulating googles rules to charge a year with no escape makes it sketchy.

Says it only has in app purchases no ads was immediately hit with an ad. Edit: your response did not even address the issue. When submitting the app, you told Google that it does NOT contain ads, but the first screen has an ad up top for another company (not your own upgrade product). I was also hit with a full-screen ad within seconds of exploring the app. You lied about the product, so I have no reason to trust you.

This app isn't even worth rating 0 stars. If there was a way to take away stars, I would do so much that this app would have to be removed from the play store. Tuning isn't accurate, riddled with adds unless you pay a monthly fee that is shoved in your face everything you open the app, and to top it all off, IT DOESNT EVEN DO A GOOD JOB AT TUNING!!!!! I would be tuning my guitar, specifically at the fourth string, and it would constantly show me other strings. Just buy a regular tuner...
