OneBeat Guitar Tools puts everything you reach for every practice session one tap apart: a rock-solid metronome, a precision tuner, the circle of fifths, a complete chord library, and a built-in practice plan with session history. Zero ads, no accounts, and no subscriptions required for core tools. METRONOME Tap tempo, adjustable accent patterns, subdivisions, and a range from 40 to 240 BPM. Each beat is scheduled directly to audio hardware ahead of time rather than fired from a software timer, so the pulse stays sample-accurate instead of drifting or jittering mid-bar. Move the tempo slider while playing and it smoothly retunes the pulse without restarting the bar. TUNER Real-time, ultra-responsive pitch detection with a clear gauge showing exactly how sharp or flat you are, down to the cent and Hz. Built with acoustic stabilization: the reading only updates when the note behind it is steady, settling on an accurate reading instead of flickering erratically. CIRCLE OF FIFTHS An interactive circle showing major keys, relative minors, and key signatures at a glance. Tap any key wedge to inspect its accidentals and relative minor chords, and the chord library will follow you there automatically. CHORDS Major, minor, dominant 7th, and minor 7th voicings across all twelve roots. Clear fretboard diagrams with open and muted string indicators, fingerings, and notes spelled out under each voicing. The diagram follows your chosen board look — Maple, Rosewood, Ebony or Lines, with dot or trapezoid inlays. PRACTICE PLAN & FOCUS TIMER A session stopwatch and structured routine checklist right at the top of every screen: • Set your daily practice routine and time budget (warmups, scales, chord changes, songs). • Check off exercises as you complete them during your session. • Track your focus time with automatic session logging. • Review your complete practice history, daily breakdown, and weekly totals. BUILT FOR DISTRACTION-FREE PRACTICE • 100% Ad-Free: Zero banner ads, zero full-screen video interruptions, and zero tracking. • No Account Needed: Everything runs completely on-device. No logins or cloud sync required. • Keeps Screen Awake: The display stays on while your metronome or tuner is active. • Universal Design: Optimized layout for iPhone and iPad. ONEBEAT TOOLS PRO The metronome, tuner, circle of fifths, chord reference, practice plan, and session logs are 100% free and always will be. An optional Pro subscription unlocks the appearance settings — custom accent colors and themes (Terracotta, Sage, Soft Plum, Mustard, Dusty Rose, Dusty Blue) plus four fretboard styles and two inlay styles for the chord diagrams — and supports independent development. • Monthly — auto-renews every month • Yearly — auto-renews every year Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple Account settings.
