That is why you should use it. ### 5/5 — 20 *2021-09-18* 7y ego ### 4/5 — Works great for standard. *2021-06-27* I think this is a wonderful app for all of the people that haven’t learned how to tune their music instrument yet, but it does have a few bugs that could be annoying if you are into the drop chords or open tunings. I use it when I am in a hurry, and it gets me within an earshot on a string or two and then I know how to finish tuning my instrument from playing over the last six months of my new pass time hobby. ### 5/5 — Good but super small bugs *2021-02-24* I love the app it is super good it helps so much but with bugs that’s not so much but still the app will crash and some times the 3ed and 4th cored sounded the same and I could not figure out why is was doing that but the bug was that the 3ed string on my guitar would go on the 4th string but other all amazing app thank you for you time 😎😃 ### 5/5 — Great tuner *2020-04-12, version 1.5* Easy to use and has alternative tunings Gold ### 1/5 — This is so bad *2020-02-08, version 1.5* Is so bad it dose not work ### 5/5 — Works *2018-11-04, version 1.5* I’ve been looking for a free guitar tuner for drop D tuning :D ### 4/5 — Great app *2017-07-22* I don't get the rest of the bad reviews, but this has worked great for my electric and acoustic guitar. Only 4 stars because of some slight bugs ## Frequently asked questions about Standard Guitar Tuner ### What does Standard Guitar Tuner do?
