An iPhone guitar-practice app that analyzes playing, explores chords and fretboard positions, and breaks down songs on-device.

Why it surfaced

FretTutor combines five unusually concrete tools: mic-graded exercises, chord voicings, fretboard exploration, song analysis, and recorded practice takes. Its strongest promise is also its clearest constraint: recordings, music, and microphone audio stay on the iPhone, with no accounts, ads, analytics, or uploads; the site says the app is coming soon to the App Store.

This is one of 1,000 discoveries in the 2026-08-10 Domain Arrivals issue.
