It is so good

I got the app last year and I have been using it ever since. I honestly don’t have any problems with the app. The app listens to it so nicely, and I even got my guitar teacher to check if it was tuned and IT WAS!!! I love it so much, if you are deciding to download the app do so.

Tbh I had my doubts and thought that it wasn’t listening or just didn’t tune it right, but I was shocked that the app was made so nicely. Thank you Simply Tuner for making Tuning much easier. 🙏

I have no need to try to learn the cords because I have classes but if you do there are tons of other Reviews to read from. Hopefully you find what you are looking for..

SimplyTuner (Guitar Tuner) Review

Love the app. The software that has gone into this app has been very beneficial to my learning. I am not good with tuning guitars, and this app has helped guide me to know what sounds “right”. This app is not only beneficial to me, but to my peers, friends, and classmates. The next person to use my guitar will have it already for them (tuning wise), and will be all set to go. This app deserves a 5 start review. It has really helped me, and others, and is very beneficial to our learning. Thank you to SimplyGuitar for providing a free, easy-to-use app. I couldn’t have gone this far without your app.

I got a ukulele two weeks ago and all the videos and apps I watched and downloaded only helped a little bit. But this app was wonderful but my ukelele sound a bit high but still, it helped and all the other apps were so confusing but I don’t know if it’s just me. But I definitely recommend it but it takes like almost 30 minutes to do it but worth it- and I believe there is no cost!!!!

Developer Response ,
