Huge potential with this great tuner

I bought it right away. Very few apps have this level of professionalism; the developers of this tuner have started something sweet.The developers even published well written documentation for their app! Amazing!!I just hope they aren't finished yet. There are a few minor features that I'd love to see.1. I really need the ability to create and save my own custom tunings. This app doesn't have any of the tunings that I'm currently experimenting with, so that's frustrating.2. I really need to tune lower than 428 for the concert pitch. That sounds strange, but I play classical guitar and I simply cannot tune up to New Standard tuning without lowering the relative pitch. Several other tuner apps go as low as 400 hz. I also play electric guitar with 13 guage strings, which has led to similar issues with needing tune down.

Very responsive developer quickly implementing requested features. Tuner seems accurate, even on electric bass. Spectrum analyzer is a useful bonus. I highly reccomend this tuner, and if there's something that bugs you about it, contact support and I believe they will continue improving the product. This also gives me faith that the app will be updated to meet requirements for OS updates, etc.

Best I've seen thus far

This is the best tuning app on the mac that I've seen thus far. Lots of features that I haven't played with yet, but the straight up tuning is quick, identiifes my input source quickly, and appears accurate. I paid the four bucks for full app capabilities.

Developer Response
1000 thanks for supporting my work! By the way, you can check the accuracy of the tuner yourself with the app. Use the built-in test tone generator.Best wishes!

This is so much easier to use than the tuner in Logic Pro! The tuning indicator is stable and much easier to use. It doesn’t constantly jump around all over the place.
