Love the new interface — efficient and easy-to-use — and now it even has its own strobe-like listening. The temperament interface is by far the best one around, including the ability to actually tune all the chromatic notes in a meantone temperament! ### 1/5 — Crashes in iOS 9 *2015-09-20* After I updated to iOS 9 on an iPhone 6, this app fails to open. It hangs and crashes. **Developer response:** After many years, I finally got around to updating the app. Please give the newest version a try! It's been completely rewritten and expanded. ### 5/5 — Great with VoiceOver *2012-09-23* Title says it all. ### 5/5 — Wonderful Tuning App *2012-09-23* This app is easy to use and extremely accessible with the Voiceover screen-reader. It's great for tuning by ear, which is what I do, and I'm glad I won't have to carry around a brace of tuning forks anymore. :) ### 5/5 — ipegs *2010-04-02* I just downloaded ipegs and tried it with my archlute. First pression; I love it! This is what I've been waiting for. Congratulations. ### 2/5 — Willbill *2009-10-22* Needs improovements, the idea is good but some of the notes aren't right ### 5/5 — This is very good *2009-10-10* I have wasted time with other tuner apps--like the one that has to "go online" to generate an A tone. This one does what I want it to do. ### 5/5 — Perfect! *2009-08-03* This app is a godsend. It literally allows one to tune every possible innstrument that's tuneable. I would definitely pay for an app this good. I'll never need another tuner again! ### 5/5 — Great app, great price-- save $100+ compared with Korg *2009-06-10* This is a great app. Very useful and accurate. User-friendly, intuitive, and adjustable. It is a must for anyone interested in baroque and Renaissance music-- and anyone interested in the expressive possibilities of non-equal temperament. It is good for keyboards, lutes, viols, harps, and modern instruments. No sloppy tuning meters It is my favorite of the 3 historical temp/ tuning apps by far... And you can't beat the price. Thanks! I look forward to more historical temps...

New in this version: - You can now mark temperaments as favorites, and you can filter the list by them. - The previous version had 4 presets for A4 (392, 415, 440, 465). Now, you can change those or add your own! (hat tip to Jeroen). - The actions you can take on a temperament are now also available if you long-press on a temperament in the list. - A4 could be set to any value between 380 and 470 Hz. I widened it to 350-500 Hz (you can thank Dan for that one). - I removed the "colored fill" option for the tuner. It's not working the way I want to, and I need a little more time to think about how to improve it. ### 4.1 — 2025-11-17 iPegs has been rewritten from the ground up, expanded, revised, and improved. New features include a standard tuner, more temperaments, and the ability to add your own temperaments. ### 1.1 — 2009-07-03 - Improved sound: the sound is louder overall, and lower notes are much easier to hear. - Corrected spelling of Bradley Lehman's name in the temperaments list. - Distinguished between Young's first and second temperaments. ### 1.0 — 2009-06-08 No release notes. ## Apps similar to iPegs | App | Rating | Price | Category | | --- | --- | --- | --- | | [Partifier: extract score parts](https://appshunter.io/ios/app/partifier-extract-score-parts/id1514964461) | 3.3 (4) | $8.99 | Music | | [ECDTunes Vol. 3](https://appshunter.io/ios/app/ecdtunes-vol-3/id1637750088) | — | $24.99 | Music | | [Nova Tuner](https://appshunter.io/ios/app/nova-tuner/id1589542148) | 4.7 (32) | $7.99 | Music | | [Well Tempered](https://appshunter.io/ios/app/well-tempered/id303514313) | 3.5 (2) | $4.99 | Music | | [Leipziger Notenspuren App](https://appshunter.io/ios/app/leipziger-notenspuren-app/id6443801834) | — | Free | Music | | [ECD Tunes](https://appshunter.io/ios/app/ecd-tunes/id721818937) | 4.0 (3) | $40.99 | Music | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
