About this app
Build any interval sequence. Launch it in one tap from your home screen.
Timerium is the sequential interval timer for Android built around one idea: your routines should run themselves. Chain unlimited timer steps together, name each one, and let Timerium auto-advance through your HIIT workout, Pomodoro focus blocks, morning routine, or custom sequence — hands-free, step by step.
⚡ ONE-TAP HOME SCREEN WIDGET Place a widget on your home screen and assign any saved routine to it. Tap once — your sequence starts instantly. No unlocking, no navigating, no waiting. Three widget sizes (2×1, 3×1, 4×1) resize to fit your layout.
⏱️ SEQUENTIAL INTERVAL TIMER The flagship feature. Add as many steps as you need. Name each one — Warm-Up, Sprint, Rest, Focus, Break — anything. Each step runs its own countdown and auto-advances to the next. Skip, pause, loop, or reset at any point. The sequence keeps running in the background if you switch apps.
• Drag-and-drop reordering • Per-step completion sounds (Chime, Bell, Glass, or your own audio file) with instant live preview inside the setup dialog • Loop mode for continuous circuits • Live "Next up" preview during active sessions • Auto-scroll keeps the active step always in view
🎯 BUILT-IN TEMPLATES — START IMMEDIATELY Five professional routines ship ready to use:
• Classic Pomodoro — 4 × 25-min focus + 5-min breaks + 15-min long break • HIIT Workout — 3-min warm-up, 8 rounds of 30s sprint / 15s rest, 3-min cool-down • Deep Work Block — 2 × 50-min focus with 10-min recharge cycles • 20-20-20 Eye Saver — 20-min screen time, 20-second distance look-away • 7-Minute Morning Jumpstart — Hydrate, stretch, plan your day
Save your own sequences as templates and reload them anytime. You can create EMOM( Every Minute on the Minute), AMARP, Circuit Training timers with ease.
Chain multiple timers into workouts that starts in one click and does run its entire curse without your interference. You can chain Kettlebell Sprints, walk intervals Mobility timers to create complete workouts.
⏳ SINGLE TIMER & STOPWATCH Need a quick countdown? Quick-pick chips for 1 to 60 minutes — one tap to start. Multi-select chips to add durations together. Custom input with both minutes and seconds support (up to 12 hours). Interval/rounds mode for repeated bursts. Switch to Stopwatch mid-session with one tap. Distraction-free fullscreen mode for total focus.
🔔 SOUNDS, NOTIFICATIONS & VIBRATION Every step completion triggers your chosen sound and a system notification showing what just finished and what's coming next. Works when the screen is locked. Per-step sound customisation means your Warm-Up can chime softly while your Sprint end fires a sharp bell. Import any audio file from your device as a custom sound. Vibration settings are respected globally, and a low-volume warning prevents you from missing alerts.
🎨 FOUR THEMES INCLUDING AMOLED BLACK Widget Blue (signature dark), Sunrise (warm light), Forest (deep green), AMOLED Black (true black for OLED screens). Switch themes with one tap. Preview all four during onboarding before you choose.
📋 SESSION HISTORY & STATS Review your completed sessions, total focused time, and current consecutive-day usage streak directly on the history stats dashboard to track consistency over time.
🔒 100% PRIVATE. NO DATA COLLECTED. Timerium stores everything locally on your device. No account required. No data shared. No internet needed to run your timers.
