Lucid Tuner. The most beautiful tuner on the App Store. Open it and it is already listening. Fast. Listening begins as the screen appears, and the reading lands under a second from the first note. Speed here is not an adjective; it is an architecture requirement, designed in from the start. Precise. Measurably precise. Pitch detection runs on the McLeod Pitch Method: a time-domain autocorrelation computed on Apple's Accelerate framework. Worst-case error of 1.1 cents across the full chromatic range, with no octave errors in testing. The engine locks onto the fundamental, never a harmonic, so the octave is right every time. Accurate enough to track in the studio and tune before a set. Simple. Radically simple. One screen. A large note name. An in-tune state that reads immediately, in colour and in shape, so it stays clear with colour vision simulated off. Nothing on screen the moment does not call for. A4 calibration and advanced options sit behind Settings, where they belong. Beautiful. Liquid Glass, iOS 26. Three visualization styles, Beam, Strobe, and Pulse, each a different character and each glanceable in a second. The design is not decoration. Every element earns its place or it is gone. Works everywhere. Chromatic detection across the full instrument range: guitar, bass, ukulele, as well as other instruments. Light and Dark, both first-class. Low glare for dark stages. No login, no account, no connection required. Free to use. No ads. The complete tuner is free every day: chromatic detection, three visualization styles, A4 calibration, full accessibility. Lucid Pro unlocks unlimited tuning, instrument presets, and the tone generator for $9.99 a year, or $29.99 once for lifetime. What's included: · Real-time chromatic pitch detection, guitar range and beyond · Three visualization styles (Beam, Strobe, Pulse); choose the character that fits the room · Perfect-lock state: a distinct, colour-safe signal within 2 cents · A4 calibration, 390–480 Hz in 1 Hz steps, hidden until needed · Full Light and Dark mode, both intentional · VoiceOver, Dynamic Type, and a reduced-motion variant; accessibility built in Lucid Tuner is a living product. More is coming. Auto-renewable subscription: Lucid Pro renews automatically unless turned off at least 24 hours before the end of the current period.
