Explore harmony wherever you practise. Intervals and Chords identifies possible chords from the notes you are holding and gives you immediate visual feedback on iPhone and iPad. Play the onscreen piano or connect a compatible MIDI controller to explore chords, intervals and musical notation wherever you are. SEE WHAT YOU’RE PLAYING
 • Identify complete chords and inversions 
• View note names and the intervals that shape each chord 
• Compare multiple valid interpretations of the same notes 
• See notes written on treble and bass staves
 • Highlight notes belonging to your selected major key LEARN IN CONTEXT 
Choose from 15 major keys, or use a keyless mode that prefers flats or sharps. Optional Roman-numeral scale degrees help connect each chord to the selected key. Valid chords outside that key are clearly identified without treating them as mistakes. GO DEEPER WHEN YOU’RE READY 
Advanced interpretation options can identify incomplete and rootless voicings or detect played scales. Beginner-friendly defaults keep complete chords and inversions at the top, so the most useful answers appear first. MADE FOR IPHONE AND IPAD
 Use the app as a portable music-theory companion at your instrument, in a lesson or while practising away from your desk. The interface adapts to iPhone and iPad, with support for accessible text and VoiceOver. Intervals and Chords analyses the notes currently held. It does not analyse chord progressions or attempt to determine a chord’s musical function within a composition. ## Key features - Real-time chord detection - Key selection for chord adaptation - Enhanced chord rendering - Exploration of inversions and voicings - Instant musical feedback ## Chart rankings - #197 in Top Paid · Music (US App Store) ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/intervals-and-chords/id6447244430/reviews.md ### 5/5 — Excellent. *2025-08-31* The best one available on IOS. Excellent customer support from a developer who listens. ### 5/5 — Great app! *2024-11-20* One item at the top of my wish list is to add a clear button to erase all the notes at once rather than having to pick each note at a time when before moving to entering a new chord. **Developer response:** Thank you for your review. Clear button is now an option you can select. Enjoy! ### 4/5 — Developer helped me solve my problem *2024-10-05* When I first opened it, I couldn’t erase the existing chord. The developer reset my screen and now I can clear the screen of the chord. He also sent me a link to a video on connecting my iPad to my keyboard. The app really does its job, and I’d the most cost effective way to analyze a tricky chord. **Developer response:** Thank you so much for updating your review! I'm sorry for the trouble you initially experienced, but I’m glad I could help resolve it for you. I'm always happy to assist in any way I can. It's always fascinating to see the different ways people use the app, and your case is definitely an interesting one! Feel free to reach out anytime - I'm always here to help. ### 1/5 — No Way to Clear notes from keyboard and enter new set of Notes *2024-10-01* When I opened it, it was displaying a C Maj 7 chord. There was no way to clear that away and enter a new set of notes. Pressing notes on the keyboard only adds them to the C chord. It’s useless the way it is now. App support only states privacy policy, so no support. **Developer response:** Thank you for your feedback, and we’re sorry for any trouble this has caused. We’ve tried to replicate the issue but haven’t been able to, as both screen touches and MIDI-connected instruments should clear the notes. If you’re open to helping us debug this, please reach out via the email address in the "Contact Us" section on the support page. In the meantime, we’ll remove the initial chord, which may resolve the issue. This change will take a few days to go through the App Store review process. We appreciate your patience. ### 5/5 — The Chord App I’ve Been Looking For *2023-12-31* I’ve been looking for an app that displays chord names when I play them on my MIDI keyboard, and I finally found this one. It’s simple to set up and use, and it does this one thing very well. Great app! It was hard to find but worth the search. **Developer response:** Thank you for a nice review, I’m delighted you’re finding the app useful. ### 5/5 — Cool app *2023-09-02* I’m really enjoying this app **Developer response:** Thank you! ## Frequently asked questions about Intervals and Chords ### What is Intervals and Chords?
