ClockChime is more than an hourly chime — it's a talking desk clock and a focus companion for your bedside, desk and workspace. Built natively in SwiftUI: instant to launch, feather-light on battery, and completely offline. Every hour, a clear voice tells you the time, so you never have to pick up your phone to know what it is. ◆ 18 FULL-SCREEN CLOCK FACES • Flip Clock with authentic split-flap animation and satisfying tick sounds • Calendar Wall with bold oversized date typography • Halo and LED — a focus progress ring and retro fluorescent digits • Seven analog dials: railway, index, minimal, crosshair, sector, grid and hairline • Five typographic faces: vertical, split, offset, stencil and broadsheet • Scale Lab — read the time on a ruler and a vernier caliper • Works in portrait and landscape, with an always-on option that turns your device into a bedside clock ◆ FOCUS TIMER & NATURE SOUNDS • Set any duration and watch the countdown live on the clock face • Six soothing nature soundscapes: rain, ocean waves, wind, stream, birdsong and crickets • A completion chime and an end notification — never lose track, even if you leave the app ◆ CHIMES, DOWN TO EVERY DETAIL • All 24 hours individually switchable — hourly chimes are free forever • Half-hour chimes for tighter time awareness • Native iOS text-to-speech with selectable premium voices: crisp and instant • Automatically muted in silent mode or during calls — respectful in meetings and at night • Choose the weekdays you want chimes to be active ◆ CUSTOM ALERTS THAT SPEAK • Set a personal reminder to be announced as spoken text, a system voice, a chosen sound, or even your own recorded voice ◆ SHAKE TO TELL THE TIME Give your phone a gentle shake and hear the current time — no screen required. ◆ PURE NATIVE PERFORMANCE • Written in SwiftUI, not a wrapped web page — fast launch, buttery animation • Tiny memory footprint; background scheduling keeps chimes alive on the lock screen • Fully supports Dark Mode, Dynamic Type and VoiceOver — a genuine talking clock for low-vision users • Interface and voice available in 12 languages ◆ FREE VS UNLOCK ALL FEATURES Free forever: hourly voice chime, smart mute, weekday scheduling, plus the Flip and Calendar Wall faces. One-time purchase unlocks: half-hour chimes, shake-to-tell, custom alerts, premium voices, the other 16 clock faces, flip themes (including your own photo), tick sounds, and the focus timer with nature soundscapes.
