The Tonal Energy Tuner is the most complete application I have used with my band. The waveform page, the instrument sounds, and the ability to tune and play samples in just or equal temperament is extremely beneficial for my students. I highly recommend it for any grade level!

TonalEnergy is a must-have for any serious musician. It's a full suite of tools in one app; the tuner, tone generator, recorder, metronome and beautiful interface make it one of the best tools for musicians out there, period.

This is hands-down the best and most functional tuner I have encountered.  It is equally powerful as an interactive personal device and as an aid in the full wind ensemble setting. The sampled sounds are authentic and appropriate for modeling characteristic sounds of acoustic wind instruments.  It is both sophisticated and kid-friendly as my colleagues and high school students have discovered.

I've been waiting for the perfect tuner for a lifetime. Finally, the TonalEnergy Tuner with "just intonation" is an invaluable teaching tool for musicians of all ages and abilities. This is a must-have application in one's arsenal of musical tools.
