It is free and easy to use having ukelele and violin that I was looking for. It has auto and manual mode. You can play the string to compare the sound if you wish to. It shows both required frequency and string sound frequency so you know what the difference is. It shows pointer as well to know whether it is high or low. Best of all I see the picture of the instrument I select and highlight the matching string when in auto mode. Thank you so much.

Absolute best I've come across. Fast, Accurate, multiple tuning options from standard, drop C, Drop D, half step down, two steps down, as well as several other options. Auto string detection so you don't have to press anything if you're tuning and moving from 6th, 5th ,4th to the 1st. Not just for guitar but for bass, violin, ukulele and regular chromatic tuner. All in the free version, the ads aren't overwhelming or anything that will make you not want to use it.

Very nice app! So far, only one request: could you please add Numeric/Nashville Notation to the choices? So many jazz musicians, military band musicians, and studio musicians use it, and it's instantly transposable into any key from there, if you're short on time, or you're not sure what key was original, or preferred. You already have a notation language option set up for do, re, mi...even to be able to have an option within there to use 1, 2, 3, vs. do, re, mi would be incredible.
