Meet Trip Buddy.

Auto-SOS Dispatch
Triggers emergency messages automatically if you are completely unresponsive to the arrival alarm.
Zero-Knowledge Privacy
Your location coordinates remain private and local. Coordinates are shared with contacts ONLY during active SOS emergencies.
Live Cloud Tracking

■ GPS Tracking Active
GPS fails underground. We don't.
Most alarm apps go blind the moment you enter a subway tunnel. Nap Alarm's Subway Watchdog detects signal loss and automatically switches to predictive tracking — keeping you on course even in the deepest metro tunnels.
2-Minute Detection Window
If GPS signal drops for more than 2 continuous minutes, Subway Watchdog activates automatically — no input required.
Predictive Stop Tracking
Uses your saved route data and average stop intervals to predict when you'll arrive — even in deep underground tunnels.
Seamless Handoff
The moment you resurface and GPS locks on, the app seamlessly hands back to live tracking without missing a beat.
How the location-based alarm works
Set up your commute alarm in 3 simple steps and get back to sleeping.
Set Destination
Search for your train station, bus stop, or save your Home/Work coordinates for instant 1-tap route setup.
Choose a Buffer
Customize your boundary rules. Want to wake up 5 minutes before arriving? Or exactly 2 kilometers away? Set your preference.
Go to Sleep
Lock your phone and rest. Our native background worker securely tracks your transit progress and wakes you up on time.
Every commute, covered. Completely.
8 powerful features engineered from the ground up for commuters who want to rest — not worry.
Smart ETA Tracking
Our Time-Based mode adapts to live traffic and transit delays. We continuously recalculate your arrival time so you wake up precisely on schedule.
Distance-Based Alarms
Prefer predictable alerts regardless of traffic? Switch to Distance Mode to trigger your alarm exactly when you enter your chosen radius — ideal for local bus routes.
Anti-Theft Shield 🛡️
Sleep securely in public. Arm the shield and the app uses your phone's accelerometer to trigger a loud, distinct alarm if someone attempts to move or snatch your device.
Smart Audio Routing
Wearing earphones? The alarm routes directly through them so you don't disturb fellow passengers. No earphones? It plays loud and clear through the speaker.
Unstoppable Alerts
Built to bypass modern Android Doze restrictions. Our alarm punches right through your lock screen and silence settings to guarantee you wake up, every single time.
Battery Optimized
By intelligently syncing GPS polling with your current travel speed and distance, we minimize battery drain so you have plenty of juice left when you arrive.
Subway Watchdog 🚇
GPS dead underground? Subway Watchdog detects signal loss and auto-switches to predictive tracking — so you never miss your metro stop, even in the deepest tunnels.
Smart Geofence Reminders 📍
The app senses when you leave Home or Work and sends a gentle nudge reminding you to set your commute alarm — before you even board the bus.
Your sleep journey, gamified.
Every nap counts. Nap Alarm tracks every minute you sleep on transit, rewards you with ranks and milestone titles, and gives you rich analytics — all synced to the cloud.
