Trip Buddy: a safety net for solo commuters

The gap an alarm alone leaves

A location alarm assumes you will wake up and act. Most of the time you do. But a commuter travelling alone late at night, in an emptying carriage, is in a situation where the interesting question is what happens if they don't respond — because that is the case where something has gone wrong and nobody knows.

Trip Buddy uses the alarm you already set as its trigger. You are not asked to check in, press a button on a schedule, or remember anything extra. If you stop the alarm normally, nothing happens at all.

Pairing with someone you trust

You generate a six-digit code in the Trip Buddy Hub and share it with a friend. Pairing is deliberate on both sides — nobody can attach themselves to your trips without that code.

• One-way — they can be alerted about you. Useful when one person does the late commute.
• Two-way — either of you can be alerted about the other. Useful for flatmates or partners on opposite shifts.

What counts as an emergency

Trip Buddy only arms itself during an active trip. The sequence is deliberately narrow, so it doesn't fire on ordinary events:

1. You arrive at your destination and the alarm sounds.
2. The alarm is not stopped within the expected window.
3. The app treats that as you being unresponsive and escalates.

A missed stop by itself is not an emergency. Not reacting to a loud alarm at your own destination is a much stronger signal, and that is the one the feature keys off.

What your buddy actually sees

When the escalation fires, Nap Alarm sends what it calls a Silent SOS Strike. On your buddy's phone that means:

• A loud siren that plays even if their phone is on Do Not Disturb — a normal notification at 1 a.m. would simply be slept through.
• A flashing red rescue screen with your live location on a map, so they can see where you are and which direction you are moving.
• A one-tap call button to reach you immediately.

If you wake up and stop the alarm, the emergency is deleted straight away and your buddy's siren mutes itself. A false alarm costs them a few seconds, not a night.

The privacy model

A feature that shares live location has to be clear about when it does. Nap Alarm shares yours only when both conditions are true: you have an active trip, and an emergency has been triggered. Outside of that, your buddy cannot see where you are — pairing does not grant ongoing tracking, and there is no always-on location sharing to forget about.

You can read the full details in the privacy policy, and the FAQ answers the specific questions about pairing and emergency handling.

Anti-Theft Shield

A related risk while asleep in public is simply having the phone taken. The Anti-Theft Shield watches for the signs — the handset being disconnected from its charger, moved sharply, or picked up — and sounds an immediate alarm, without waiting for your location alarm to be due.

Getting set up

Trip Buddy is part of the free, ad-supported Android app — it is not behind the Pro tier. Pair once with someone you trust, and it stays out of the way until the one journey where it matters. If you mainly travel underground, the subway alarm behaviour is worth reading alongside this.
