Stop watching the clock — we'll remind you! VoiceTimer is a smart countdown app that shows and announces how much time remains until your target. Perfect for cooking, studying, or any task where you can't keep your eyes on the screen. It reads the remaining time aloud and notifies you exactly when you choose. * A successor to "Countdown Calendar," released over 10 years ago. Key Features - At-a-Glance Countdown: Remaining time is displayed in large, easy-to-read digits. Even with multiple targets registered, the nearest one is always shown front and center. - Tap the Speaker to Hear It: Tap the speaker button to hear the current remaining time read aloud — ideal when your hands are full. Choose your language (Japanese/English) and voice (female/male). - Flexible Pre-Alerts: Combine multiple reminders from 14 timing options, from 5 seconds to 1 hour before. You'll get a voice-enabled notification even when the app is closed. You can also enable a final countdown that speaks "10, 9, 8…" for the last 10 seconds. - One-Touch Kitchen Timer: Save your most-used durations to a button for instant setup. Give them custom names, and your most-used buttons are automatically highlighted. - Repeating Timers: Daily, weekdays, weekly, or monthly — automatically restarts the countdown after each completion. - Calendar & Reminders Integration: Pick any event and start counting down to it instantly. - Always Visible on Lock Screen & Home Screen: Full Live Activities & Dynamic Island support! Check your next event at a glance with a Home Screen widget, or start a kitchen timer with one tap right from your Home Screen. - Make It Yours: Customize with 55 color themes (across 7 categories), theme-matched ambient animations (adjustable in 3 levels), and 5 alarm sounds.
