Herline checks in on you during every journey. If you don't respond, we alert your emergency contact — automatically.
Simple & Reliable
Three simple steps. That's all it takes to have a safety net on every journey.
Enter your destination, current location, and ETA. Choose how often you want check-ins — every 15 minutes, 30 minutes, or hourly.
Herline sends you regular check-in messages. Just press "I Am OK" to confirm you're safe and continue your journey.
If you don't respond, a 10-minute grace period starts. If there's still no response, your emergency contact is alerted immediately.
Everything You Need
Every feature in Herline was designed with one goal: making sure someone always knows you're okay.
Choose 15-minute, 30-minute, or hourly check-ins based on your journey and comfort level.
Set a specific time for your check-in — perfect when you can't look at your phone consistently.
A buffer before alerts are sent, accounting for signal loss or moments when you're briefly unavailable.
If you don't respond, your emergency contact receives an immediate SMS from Herline on your behalf.
Tell Herline your phone is about to die. We'll pause alerts and wait for you to reconnect before escalating.
Let the app know you're in a low-signal area. Herline adapts so your contact isn't falsely alarmed.

Step by Step
From the moment you start a journey to the moment you arrive safely — here's exactly what happens.
Sign up with your name, email, and password. Add your location and your emergency contact's name and phone number. This is the person Herline will alert if you don't respond.
Takes 2 minutesBefore you set off, open Herline and start a journey. Enter where you're going, your current location, and your expected arrival time. Then choose your check-in interval — 15 minutes, 30 minutes, or every hour.
15 seconds to set upAt each interval you'll receive a message. The messages rotate naturally — "still okay?", "any change in route?", "you're doing great!" Just press I Am OK to confirm you're safe.
One tap to confirmIf a check-in passes without a response, a 10-minute grace period begins. You'll be notified clearly. This covers signal drops, a briefly unavailable phone, or any short delay.
10 minutes of bufferIf the grace period ends with no response, your emergency contact receives an SMS: "This is Herline Services. After the given grace period, there has been no response from [your name]. Please check in with them urgently."
Automatic and instantWhen you reach your destination, press I Have Arrived. Herline ends the journey: "Great! You made it. Ending OTP now." No more check-ins. You're done.

Our Story
Herline was created for anyone who has ever wished someone knew where they were.
Too many people travel alone without a safety net. Whether it's a late-night journey home, a solo trip, or simply walking back from a friend's house — there are moments when you just want someone to know you're okay.
We wanted something simpler — a quiet companion that checks in on you and only escalates when it needs to.
"Your safety should be covered by default — not something you have to remember to set up."
Herline is built around one core belief: if you don't respond, someone should know. The app handles that automatically, without drama, without false alarms, and without requiring anything more than a tap on a button.
Herline is for anyone who travels alone and values peace of mind.
