Description

Clean native iOS metronome for daily harmonica / music practice — precise timing without ads, accounts, or clutter. Built for the same slow reps / muscle memory lane as projects/music-production harmonica work.

Portfolio note: Metronaut is Darcy's second live iOS app on the App Store alongside projects/lunarcast.

Features

Feature	Detail
Tempo	Dial swipe, ±1 steppers, direct BPM entry (20–300), tap tempo
Time signatures	4/4 and 3/4 with accented downbeats
Feedback	Visual pulse (animated ring + beat dots) and/or warm synthesized click — each toggleable
Modes	Visual only, audio only, or both
Keep awake	Screen stays on while the app is open — auto-lock / screen timeout fixed before launch

Tech stack

• SwiftUI, iOS 17+, Xcode 16+

Business

• Free — no IAP, no ads at launch (same posture as projects/lunarcast / projects/triviabalance).
• Maintenance: bug fixes and small UX polish as needed; not a top-priority product-building line.
