Never miss your stop again. You look up. Nothing outside the window looks familiar. Your stop was three stops ago. Stopzone is an alarm for your destination. Pin the stop you're heading to, Set the desired radius, press Start, and close your eyes. When you enter the zone around your stop, Stopzone rings a real alarm. One that plays through Silent mode and through Focus. A REAL ALARM, NOT A NOTIFICATION Notifications don't wake anyone with their phone in a pocket. Stopzone plays through your media volume, not your ringer volume, so it's louder than a notification, Because it isn't one. HOW IT WORKS - Pick a stop by searching it, drop a pin - Choose how early you want to be alerted, from 300 m to 5 km - Press Start - Get alerted when you enter the zone, and press I'M UP ALERTS YOU IN STAGES First a quiet voice in your earphones telling you where you are, so nobody else hears a thing. Then, if you don't respond, the loud alarm through the speaker. THREE MODES, ONE ENGINE - Commute: your saved stops, one tap to start - Night Out: your home stop, ready after 22:00, oversized controls - Travel: works with zero mobile data, your stop saved offline BUILT SO IT CANNOT MISS A backup alarm is set the moment your journey starts, so you're woken even if GPS drops out in a tunnel. If your phone loses signal entirely, the alarm still rings — it never needs the network to fire. MORNING ALARMS TOO Set your regular wake-up alarms in the same app, with the same voices. YOUR LOCATION NEVER LEAVES YOUR PHONE All the distance maths happens on your device. We don't upload your location, your stops, or where you travel. There's no account, no email, no login, Ever. SEE IT WORK BEFORE YOU RELY ON IT Onboarding includes a full simulated journey that runs the real alarm engine at your desk, so you can hear exactly what happens at your stop. TRACK YOUR STOPS Stops made, streaks, badges, and the hours you've rested on the way. Stopzone doesn't predict arrival times and doesn't navigate. It shows one number, how far you are from your stop, because that's the number that's actually exact. SUBSCRIPTION Stopzone requires a subscription. - Yearly — $39.99 per year - Monthly — $9.99 per month - Weekly — $4.99 per week Prices are in USD and may vary by region.
