AtCoder Alarm vs Dawn

This App is an alarm clock that doesn't stop until solving an easy problem of AtCoder (competitive programming web site). The problem is chosen randomly from "A" tasks of past ABCs. Let's make sure to wake up! * Pre-registration with AtCoder is required.

Dawn turns your iPhone into a beautiful bedside clock — a calm space for focus, sleep, and the moments in between. WHY DAWN While other clock apps just tell time, Dawn helps you spend it well. Whether you're starting a 25-minute Pomodoro, winding down for the night, or charging on your nightstand, Dawn brings six handcrafted clock faces, a focused-timer, and gentle sleep tracking into one calm, ad-light experience. KEY FEATURES — Six Clock Faces Choose from Sunrise (default warm gradient), Minimal, Pixel, Nebula, Bloom, and Classic. Tap to switch instantly. Every face is hand-tuned for that quick "I want to look at it" feeling. — Bedside Clock Mode One tap puts your iPhone in full-screen Bedside mode. Soft glow, anti–burn-in drift, perfect when plugged in on your nightstand. The room gets a beautiful clock; you get a phone you don't pick up at midnight. — Pomodoro Timer With Streaks Standard 25-minute or any custom duration (1–180 min). Add a task name, watch the ring fill, and finish to a clean checkmark. Track daily counts and your current streak — a gentle nudge without guilt. — Sleep With a Bedtime Ring Set your bedtime and wake time on a single circular ring. Tap "Start Sleep" to dim the screen into a calm, dark clock. Wake up to a gradient sunrise button. See your last 7 days as a quiet bar chart. — Real Alarms, With Honest Limits Multiple alarms, weekday repeat, snooze, fade-in, and seven sound presets including Radar, Chimes, and Crystals (iOS system sounds — Apple's originals aren't available to third-party apps). We tell you up front: iOS may suppress third-party alarms in Silent or Focus mode. Keep the ringer on. — World Clock With 80+ Cities Pin Beijing, London, Tokyo, or any of 80+ cities. Tap the main display to pick which city is your "home." Drag the A–Z index to jump anywhere in the list (with Contacts-style haptics). — Stopwatch & Timer A full-screen rounded-monospace stopwatch (lap support), and a timer with custom Pomodoro-style presets you build yourself. Long-press to delete; tap "+" to add. — Widgets Lock-screen widgets (circular, rectangular, inline) and Home-screen widgets (Small / Medium / Large). Add your favorite clock face to your wallpaper. — Eight Languages English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Português — all hand-tuned, not machine-translated.
