CyberTuner vs PianoMeter

Reyburn CyberTuner, the pro piano technician's gold standard tuning software for over 30 years. Continuously refined through three decades of professional feedback from master piano technicians. This is a professional piano technicians' tuning tool. 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 (RPT) member of the PTG with years of concert tuning and prep experience as well as "in the trenches" home tunings and repairs. Built on the collective knowledge 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. • Concert Tune mode combines the best of Fine Tune and Smart Tune, customized for 7 foot (210cm) and 9 foot (275cm) concert instruments. • 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). • Fast, high-resolution spinner provides unsurpassed stability and unisons. • New: Apple Metal graphics framework for improved battery life and responsiveness. • New: CyberAssist built-in tech support provides instant answers 24/7. • New: iCloud Sync with merge files feature keeps your files safe. • New: CyberEar AI Mode creates tunings which challenge even the best aural tuners. • Occasional internet connection (approximately 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 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 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 the App Store and at: www.cybertuner.com/ircteula

PianoMeter is a piano tuning app for professionals and hobbyists that will transform your iPhone or iPad into a professional quality electronic tuning aid. NOTE The "free" version of this app is primarily for evaluation, and it only allows you to tune notes on the piano between C3 and C5. To tune the entire piano you will need to buy an upgrade through an in-app purchase. What makes PianoMeter unique: Unlike most musical instruments, pianos cannot be simply tuned to the generic "equal temperament" frequencies that most tuning apps use. Piano tuning must be "stretched" wide of equal temperament for the piano to sound good. Traditionally this is done by professional piano tuners listening to complicated beat ratios of various musical intervals. PianoMeter makes the process more straightforward by directly measuring the tonal characteristics ("inharmonicity") of each note on the piano and automatically calculating the ideal “stretch” or offset from equal temperament. In other words, it creates a custom tuning for each piano with the best compromise between musical intervals like octaves, fifths, fourths, and twelfths, the way aural piano tuners do when fine-tuning. Functionality and pricing: There are three levels of functionality: a free (evaluation) version, a paid "plus" version with basic tuning functionality, and a "professional" version with features geared towards professional piano tuners. The extra functionality is unlocked through one-time in-app purchases. The Free version includes the following limited functionality: • Tuning functionality for the mid-range of the piano only • Automatic note detection • Ability to measure each note on the piano to see how its current tuning compares to the ideal tuning curve (see if a piano is roughly in tune) • Swipe in the graphing area to show a live frequency spectrum or the inharmonicity of measured notes. Upgrading to "Plus" adds the following functionality: • Tuning functionality for the entire piano • Tune to frequency standards other than A=440 • Tune to historical or custom temperaments • Calibrate device to an external frequency source • A TuneLab-inspired Peak View as an alternative visualization of the pitch using the FFT spectrum. Upgrading to Professional unlocks all features of the "Plus" version, plus the following: • Save and load tuning files, so a piano doesn't need to be re-measured each time it is tuned • Pitch raise mode that calculates overpull for an initial first pass "rough" tuning (for pianos that are extremely flat) • Custom tuning styles: create a custom tuning curve by adjusting interval weighting and stretch • Multi-partial tone generator that plays the target frequencies • New colorful "Tonal Energy" display that shows a brief history of the pitch • Automatically back up tuning files to iCloud • Access to all future features and enhancements Upgrade costs: Free to Plus (approximately US$30) Free to Pro (approximately US$350) Note about permissions This app requires permission to access the microphone on your device and permission to read and write files. In the Pro version, the app can optionally use the "location" permission to tag your tuning files with their geolocation.
