“Anyone wanting to really understand what's happening ‘under the hood’ should study and use this app. It should accelerate their learning process significantly.”

“This is very brilliant… it works quite well (even with open unisons)! I'm very impressed.”

“[One of the huge benefits] is to see just how well we actually tune, compared to how we think we tune, either aurally or electronically.”

US$199, once. About what you charge for one tuning, and it turns up to every tuning after that. No subscription, ever.
✓ = documented by the vendor. –* = not documented in the vendor's manual or store listing, checked August 2026. CyberTuner is a one-time purchase plus a required US$84.99/yr subscription to keep its full 88-note mode; pianoscope is sold either one-time or by subscription; PianoMeter and TuneLab are one-time. The big apps display calculated beat rates for the solved tuning; none of them measures the live beat of an interval you play.
When the 14 days end, nothing is charged and nothing is deleted. The app drops to the free version, which is yours forever:
Your saved tunings stay on your phone. The measured ones simply wait until you buy.
Every install starts with 14 days of the full app. Nothing is charged until you choose to buy.
Launching September 2026.
