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

In subsequent years CyberCare one year subscriptions may be purchased in-app with automatic renewal option. See "In-App Purchases" for CyberCare price in local currency. If your CyberCare Subscription lapses, iRCT will continue to function in original Standard mode.

THE ABOVE IS ONLY A SYNOPSIS OF PART OF THE CYBERTUNER LICENSE AGREEMENT. REFER TO THE LEGAL AGREEMENT BELOW FOR FULL DETAILS. IF YOU DO NOT AGREE WITH THE TERMS IN THE LEGAL AGREEMENT, DO NOT PURCHASE A CYBERTUNER LICENSE. Terms of Use and Application License Agreement> Privacy Policy> • New for iRCT! 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 connects to "CyberCloud" to automatically calibrate to A440.00. • 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). • iRCT tuning files are fully compatible with RCT/Laptop and Pocket RCT. iRCT supports import and export of tuning files through iTunes running on Windows or MacOS X. • Faster and higher resolution spinner than ever before gives you unsurpassed stability and unisons. • All iRCT views rotate to support all four screen orientations. • iRCT requires iOS 8.0 or later. iRCT runs on any iPad in iPhone mode in 1x or 2x size. Occasional internet connection required to calibrate A440 and confirm CyberCare subscription.

    As a concert and university technician, this is my most valuable tool. Would not be where I am today without it. 7/18/17...Indispensable.

    I am a professional piano technician with 37 years experience, and started using Cybertuner almost 20 years ago-not long after Dean developed it for Macintosh. (Haha, I think I still have the floppy disk somewhere- serial number 73). I lugged my laptop to work for years so I could use RCT. With each new incarnation of the program I eagerly upgraded- with development of the Windows version I moved to a Pocket PC (which by the way I struggled with, being a Mac guy). But RCT on that device was a seamless transition. And when iRCT was announced I was overjoyed! Now my iPad mini running iRCT and FileMaker Go accompany me everywhere there is a piano, and there are a lot of them in my life. I owe much of my success to Reyburn CyberTuner. Thank you Dean!
  • Just great

    I've tuned aurally for about 15 years, working for colleges, dealers, churches, television studios etc. In the last few years I had considered buying this app, but was hesitant because I wasn't sure how big of a difference it would make day to day. The last version of this software I had tried was on a PDA back in 2006, and prior to that I had used an old OS9 PowerBook occasionally. Neither of those solutions come close to what the new iRCT version is capable of, running on my 9.7" iPad Pro. It's fast, accurate, lightweight, and easy to see! Smart tune and concert smart tune are quite possibly the best thing that's ever happened to me! (Not really exaggerating here haha). At the end of every workday, I am thankful to own this incredible app and greatly appreciate the work of Dean Reyburn and the team of people that make this app possible.

    Been using Sanderson for 27 years. The Cyber Tuner is very easy to use. Using both tuners side by side the Cyber has some very nice advantages. Great job to the the great minds that produced a wonderful product. Going to be fun detuning daily.
  • Great app

    Love this app!
  • Great tuner!

    I put off buying CyberTuner, but I have been very pleasantly surprised at how well this tuner works. The pianos I tune regularly are more stable, and it also gets good results with the pianos that haven't been tuned in decades. I'm also using it to prepare for the RPT tuning exam. The constant improvements are a real plus.
  • Reyburn's app rocks!

    I've been a "CyberTuner" user for fifteen years. I finally upgraded to the Apple version and find it brilliant. It's quite user-friendly and accessible.
