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

Excellent for keyboard instruments

This app is accurate, easy to use, and will work for any instrument. It is particularly useful for players of keyboard instruments who want to tune in something other than equal temperament. The app offers the largest number of historical tunings I have seen anywhere, and they are well researched and documented.

Developer Response ,

So great to hear! 🙌 We spend a ton of time and effort researching historical temperaments, and are thrilled to hear how they're helpful to you! 🎹
