Historical Temperaments

One of the reasons I bought this app is that it has many historical temperaments built-in. I play the lute whose moveable frets allow one to adjust the tempering for individual pieces. I usually play in 1/6 comma meantone temperament, in which some of the enharmonic equivalents - for example G# and Ab - are VERY different notes. Unfortunately, VITALTuner only shows one of these and I have to tune the other by ear. It’s a good tool for those of us exploring early music, but not quite there yet. (If you have no idea what I’m talking about, everything else is worth 5 stars.)

Developer Response ,

Thank you for the review and the feedback, much appreciated! 🙏 This is definitely on our radar for features we'd like to add. It's useful for different octaves as well, if you'd like e.g. your high G string to be at a slightly different offset from your low G course. We'd love to email you when we have news if you reach out to us at

Great tuner!

I really like this tuner. It seems very accurate, and the features and versatility are great! The main reason I wanted this app was to explore sweeter tunings and specifically use it for “James Taylor” tuning. But I can’t figure out how to set up the custom offsets correctly. How can I have a different offset for the high and low “E” strings on a guitar? Is that even possible or would I have to just do it manually for one of the “e” strings.

Developer Response ,

Thanks for the feedback, 🙏 and for writing to us as where we were able to give a more detailed answer. The ability to assign offsets to individual pitches is on our list of feature considerations, and your request has been added. We'll follow up with you when we have news, stay tuned! 👀

To be taken with a grain of salt

Looking at it from my perspective, I’m not an avid players of my guitar, but I enjoy it and want to learn it more than my basic knowledge. But reading through reviews of other tuning apps was like mini-horror stories. So I dropped the one time purchase for this app and after just finishing using it must say I am happy with the seeming effectiveness of it as well as it’s simplicity to use

That's so great to hear and has made our day! 💯
