This is a great, easy to use app. That being said, I do have three features I'd like to see added. I actually had to download the Fender Tune app as well, because it's the only tuner that seems to have opened E. However, I much prefer your UI. Secondly, I build guitars as a hobby, and I would like to see "intonation" tuning in the app for guitar and bass. These would be exactly 1 octave above standard pitch. Lastly, I'd like to be able to create and save my own tuning.

Works great on my Samsung tablet, however on my redmi 10 phone for the same frequency it now shows that my ukulele and guitar are NOT in tune. Learned how to compensate but still, why it reads in tune on tablet and not in tune on phone is a big problem. (I compared both devices side by side).

Temu advert pops up, counts down and then won't clear or allow me to clear rendering the app unusable 🤦

I would have given you 5 stars till after the second time I used it. Now it's gone in to two steps down mode and won't go back into standard E.A.D.G.B.E tuning unless I pay the £6.99. I was going pay it next month, but I'm not so sure I will now, I don't like being pressured by greedy company's.
