What makes Reyburn CyberTuner for iOS (or “iRCT”) superior to other tuning software? Ease of use. Clarity of functions.

Concert Tune mode combines the best of Fine Tune and Smart Tune but customized for 7 foot (210cm) and 9 foot (275cm) concert instruments. • NEW! Aural Tutor expert system analyzes your aural tuning and suggests intervals and check notes for improving your aural skills. • Extraordinarily accurate and fast pitch correction with iRCT’s Smart Tune and Pitch Raise modes. These modes use a US Patented expert system to individually predict every note on the piano. • iRCT creates aural-quality tunings by directly matching sampled partials, just as concert aural tuners do. • iRCT accommodates all experience levels, giving beginning tuners a very simple interface, but offers advanced tuners customizable stretch choices. • iRCT is an “expert system” which automatically senses and compensates for short scaling in spinets, small grands, etc. • iRCT creates musical tunings from low bass to high treble because accurate multi-partial samples (to .01¢) are taken across a wide array of sample notes (A1, A2, A3, A4, A5 and A6). • Faster and higher resolution spinner than ever before gives you unsurpassed stability and unisons. • Occasional internet connection (once a month) required to calibrate A440. 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. See "In-App Purchases" for CyberCare price in local currency. If your CyberCare Subscription lapses, iRCT will continue to function in original Standard mode. In subsequent years CyberCare one year subscriptions may be purchased in-app with automatic renewal option: – Payment will be charged to iTunes Account at confirmation of purchase. – Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. – Account will be charged for renewal within 24-hours prior to the end of the current period. – Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. 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.

IF YOU DO NOT AGREE WITH THE EULA TERMS, DO NOT PURCHASE A CYBERTUNER LICENSE. Complete Terms of Use are in the End User License Agreement (EULA) in iTunes and at:

Really amazing software. Able to make my Tunings super stable!

The Quintessential Tool

I’m a concert technician of 20 years...4-5 concert venues per week. Tune mostly Steinways for C&A, store and in customers’ homes. I would never have made it to where I am today without this tool. It is a “must!”

Simply Outstanding!

I learned aural tuning 30 years ago from my dad, who tuned for the Minnesota Orchestra. Later on, we both used digital tuners made by other companies through the years. I had watched other tuners use the RCT and thought it would be good to try it someday. Some time ago a tuner friend let me borrow his iRCT to tune a fortepiano with an historic temperament. WOW! So I finally made the decision to get this App at the end of 2019. It’s the best move I’ve ever made! The precision & flexibility is just AMAZING. Pitch corrections are dead-on. My clients & I are stunned at how beautiful their pianos sound. They were really quite good before, but this is another level altogether! Thanks Reyburns!

Does what says, very well

The more I use it, the better I and it gets.

You can always go back to aural tuning, but this app is foolproof when it comes to raising and lowering pitch which every tuning greater than +/- 4¢ has. After a pass, it settles back right on 0 for every note. Love it.

I’m a brand new tuner

I can tune pianos incredibly well and I’ve only been doing it for 1 month! I stopped trying to learn by ear because this is so good.

FINALLY--string section/break parameters are saved for each tuning record (right in the tuning file) and are recalled and entered automatically each time a tuning is selected in Smart Tune mode (and Pitch Raise also). Piano tuning is tedious enough ;) Next on my personal feature wish list might be a scrollable index (and maybe also a search box) in the Open Files screen, just like it is in the Tunings screen. With institutional clients having multiple (or many) pianos, it just seems to make for better organization and ease of use to have one tuning file for clients with numerous pianos, and perhaps one file per class of client with only one to several pianos (for example, private, church, school, piano teacher clients, etc.). Nonetheless, iRCT is a remarkable product in so many ways, and I sure don't miss the old Pocket PC/Pocket RCT... But the CyberCare subscription for $80 every year is certainly debatable, if not outright questionable, especially given the $1,000 original purchase price and the limited number of updates and feature additions. Besides, just how many truly useful features can even be added to software like this over time?

Great app!

I have tuned 100 pianos with this program so far. It’s amazing how precise CyberTuner is. The ability to do quicker pitch raises is priceless. People often say their pianos never sounded better. Customer support is great. My emails and phones calls have been responded to quickly.

Pitch Perfect Piano Tuning

Great program! Love the app!! Pitch Raises in minutes, not hours, Keep the upgrades comin. Thanks!
By 2uneUp

Great program

When I started tuning a few years ago, the app was great. Now, understanding all the aspects of it, it has been the results astounding. The app easily! Pays for itself and the quality result is well worth the investment. The P12 option has allowed me to generate insanely neat results on spinets and pianos commonly thought of as “junk” - a few calculations, and voila! Even “ye olde” sounds great. Not to say, it also has helped tremendously to have sub-bass option when tuning Bosendorfer Imperials.
