User reviews

One of the most full featured, customizable and reliable tuning assistants.

It enables my Tenitus bound hearing - a ring like the sustaining C8, to be guided to accurate representations of any pleasing tuning stretch possible. I was taught using this by very astute teachers. I benefitted from that, but this software allows what if I had to ghost every partial it would be really reckless and overly long. This enables my tunings accurate through multiple passes throughout the instrument and at least at a professional result.

Glad I finally switched

I’ve been very happy with the app!

Only App For Piano Tuning

If you want the best result in one sitting, this is the app.

A bit outdated

File system is antiquated, clumsy and time consuming. Takes too long to sample notes compared to other tuning apps. Automatic note switching is only for adjacent notes. Very overpriced app for older technology. Indicator blushing occurs over a wide range of pitch, not as precise as other apps. Have to clean up break by ear or use the time consuming AI mode which sometimes doesn’t always do a good job compared to other apps. If you don’t have strong aural tuning skills you’d be better suited with another app that doesn’t require as much clean up of the tuning. Pitch raising is only based on nearby sample notes. It doesn’t take in account what is coming after, only the notes that have come before. Very unreliable.
