Tune Master: Guitar Tuner

Overview

Tune Master is a fast, accurate chromatic tuner for guitar, bass guitar and ukulele. Open the app, play a string, and the live needle shows exactly where you are — tune up, tune down, or enjoy the green when you're in tune. HOW IT WORKS 1. Pick your instrument. 2. Play any string — the needle and note name respond in real time. 3. Follow "Tune up / Tune down" until it reads "In tune". 4. Tap a note button any time to hear its reference pitch. FREE TRIAL & PREMIUM Tune Master is free for 3 months after first launch — every feature included, no account needed. After the trial, a single one-time purchase unlocks the app forever on every device using your store account. Prices vary by country and are shown before you pay. No subscription, no ads for core tuning. You can restore an earlier purchase any time from Settings → Restore purchase. PERMISSIONS • Microphone — used only to hear your strings for live tuning. Audio never leaves your device. Made for players: bedroom practice, stage tuning, and everything between. Download Tune Master and sound right.
