Songwriter's Calculator Version 3.1.2 Our most capable version yet. Build demos faster than ever before on everything from iPhone Mini to iPad Pro. We happily welcome user feedback and suggestions for features. Help us sculpt the perfect music app. TUNER A pro-grade chromatic tuner with LED segments and a pitch-history strip. Guitar, bass, ukulele, violin, and chromatic, with an adjustable A4 reference. Built to get you from tap to tuned as fast as anything out there. IDENTIFY Build any chord and see it on piano and guitar at once, then hear it back with real instrument sounds. Don't know the chord's name? Just tap the notes on the piano or the fretboard and we'll name it. Or strum your chord and let SWC try to identify it. Includes 30 solo styles with scale overlays on the fretboard. CREATE Add the chords you found and we'll work out your likely key, then show you the chords, progressions, and scales that go with it. Everything you need to demystify the song stuck in your head. RECORD This is the one we obsessed over and will continue to improve for the foreseeable future. We put serious work into the noise cancellation and latency so multitrack recording just works, with wired headphones, AirPods, or no headphones at all. On the rare take where timing drifts, the nudge tool slides it back into place. Use our novel Key/Chord Guesser to estimate your key and chords from a recorded take. Assign that key to your demo and the fun starts: clickable chords and notes, right in your key. Play and record them with high-quality Upright Piano, Nylon-String Guitar, Electric Organ, Synth Strings, Xylophone, and a full drum kit. Or build drums and melody via sequencer. New in 3.1: a count-in before the take, and a click track in your headphones so you can play drums in time. Connect a USB audio interface and choose which input you're recording from, in mono or stereo. The app always shows what's coming in and what's going out, so you're never guessing. ## Key features - Chord and scale generation by key - Diatonic chord and scale identification - Chord progression generator with analysis - Interactive fretboard with solo styles - Chromatic tuner and metronome - Capo calculator and alternate tunings - Ear training drills for intervals and chords ## Pricing and in-app purchases Base price: $4.99. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Small Tip | $0.99 | one-time | | Big Tip | $4.99 | one-time | | Full Unlock | $4.99 | one-time | ## Chart rankings - #191 in Top Paid · Music (US App Store) ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/songwriters-calculator/id6759758294/reviews.md ### 5/5 — Impressed *2026-06-19* I tried to call their bluff and quickly create a 3-track demo with guitar and vocals and was sort of shocked by how well it turned out. It’s limited for sure, but I’m impressed ### 5/5 — Good mix of tools *2026-03-11* Combines features from a few other apps I have which I like and is cheap. My only critique is the keyboard for the chord identifier could be bigger. ## Frequently asked questions about Songwriter's Calculator ### What scales and modes does Songwriter's Calculator offer?
