Majkey

About this app

Intoniva opens straight into the tuner.

Tune guitar, bass, or ukulele automatically, select a string manually, or identify notes in chromatic mode. The cents rail shows whether a detected note is flat, sharp, or in tune. Results depend on the instrument, microphone, and background sound.

Song analysis provides estimates. Dense mixes can be ambiguous; results may need correction and do not reproduce every instrument or guitar tab.

Intoniva has no ads, account, analytics, tracking, or internet permission. Microphone audio is analyzed transiently on-device and never recorded, retained, shared, or transmitted.

Selected song files are decoded only on-device and are never copied or uploaded.

Auto-scroll uses Android Accessibility only to perform user-requested swipe gestures. It cannot retrieve screen content and does not read, store, record, or send anything shown on screen. No Shizuku is required.

Optional support in App details opens Buy Me a Coffee in an external browser. It does not unlock app features.

What’s new

Trainer controls now stay visible. Save separate Learning and Learned note sets, compare A/B notes, and loop them back to back. Note quizzes use your selected set. Chord and note questions are randomized. Chord browsing now uses grids instead of scrolling strips.
