RingSure: Alarm Clock & Timer

Tired of alarm clock apps that don't go off? You're not alone — it's the #1 complaint across every alarm app on the Play Store.

RingSure is the reliable alarm clock for heavy sleepers. It uses the same scheduling method as the built-in Android clock — the only one your phone cannot throttle — so your wake up alarm fires every single time, even in Doze mode, even after a reboot.

No more oversleeping. No more missed alarms. An alarm clock that actually works.

ALARM CLOCK
Set one-time or repeating wake up alarms for any day of the week. Choose from gentle alarm tones or loud alarm sounds for heavy sleepers. Gradual volume option starts quiet and increases over 30 seconds — perfect as a gentle alarm clock. Full-screen alarm rings over the lock screen so you never miss it. Customizable snooze length. Math problem mission to make sure you're actually awake.

COUNTDOWN TIMER
Run multiple named countdown timers at once. Quick presets (1, 3, 5, 10, 15, 20, 30 minutes) or set a custom duration. Great as a cooking timer, nap timer, or study timer. Each finished timer rings through the same reliable alarm path — no silent finishes.

STOPWATCH
Tap-to-lap with split times and best/worst lap highlighting. Perfect for workouts, running, and time tracking.

INTERVAL TIMER — HIIT & TABATA (Pro)
Configurable workout timer with work time, rest time, and rounds. Spoken voice cues announce each phase so you can focus on your exercise. Use it as a HIIT timer, Tabata timer, boxing round timer, circuit training timer, or any interval workout timer.

POMODORO FOCUS TIMER (Pro)
A distraction-free focus timer for deep work. Configurable work sessions, short breaks, and long breaks with session tracking dots. Auto-start breaks keep you in flow. Use it as a study timer for exams, a productivity timer for work, or a concentration timer when you need to get things done.

REMINDERS
Two reminder types that actually fire on time: interval reminders (every 15 minutes to 6 hours with an active window) and daily reminders (every day, every other day, or specific weekdays). Persistent notification stays visible until you act on it. Quick-start templates for drink water reminder, medication reminder, posture check, eye rest (20-20-20 rule), stretching, and plant care.

WORLD CLOCK (Pro)
Add cities across every time zone — including 30-minute and 45-minute offsets. See the current time around the world at a glance.

WHY RINGSURE IS MORE RELIABLE
Other alarm clock apps use scheduling methods that Android's battery saver can silently kill. RingSure uses AlarmManager.setAlarmClock() — the same Doze-exempt method as your phone's built-in clock. Your alarm survives Doze mode, battery optimization, app kills, and device reboots. On first launch, RingSure walks you through the exact permissions needed for bulletproof reliability.
