Reyburn CyberTuner, the pro piano technician’s gold standard tuning software tool for over 16 years. Over three years in development for iOS including a year of intensive testing by master piano technicians around the world!

This is a professsional piano technicians’ tuning tool and is priced accordingly. The 17+ rating reflects only the price. There is no Mature/Suggestive content, or any objectionable content of any kind. We expect users to already know piano tuning basics and have their own tuning equipment.

What makes Reyburn CyberTuner for iOS (or “iRCT”) superior to other tuning software? Ease of use. Clarity of functions. Intuitive and thoughtful design and programming by a Registered Piano Technician member of the PTG with years of concert tuning and prep experience as well as “in the trenches” home tunings and repairs. The piano tuning knowledge base of scores of RPTs. Flexibility to tune the way you want with unbelievable accuracy. Support by the creator, by either personal email (international) or toll-free phone (in the US & Canada) for registered users. Email listserv support is free for registered CyberTuner users.

An iRCT license includes Standard Mode (ability to tune a 13 note temperament from A3 to A4) plus a FREE one (1) year subscription to CyberCare which upgrades the mode to Premium (tune 88 notes). Also included with a CyberCare subscription are free upgrades to any new iRCT features, CyberCloud calibration, and support (if registered). In subsequent years CyberCare one year subscriptions may be purchased in-app for $79.99 USD/CAD (price varies in other currencies). If your CyberCare Subscription lapses, iRCT will continue to function in original Standard mode.

The iRCT software includes a single user license. iRCT may be used to tune pianos (or any keyboard instrument) on one and only one iOS device at a time, but may be installed on multiple iOS devices.
