About this app

An Do is a community SOS map application that helps people in distress quickly share their location and assists rescuers in finding the right route to reach them.

The application is designed with a minimalist approach, centered around the map. No complicated account registration is required: open the app, select your language, and use it immediately.

SOS and direct location sharing

When you need help, simply hold down the SOS button to create a rescue signal. The application will update your location in the background and display your GPS status, update time, and device battery level.

Name, phone number, and email are optional. You can add this information to make it easier for rescue teams to contact you, and you can also proactively choose which data is shared in each SOS session.

Finding people in need of help

Rescuers or community members can view active SOS sessions, select a case, and begin assistance.

The application provides:

The latest location of the person in need of rescue.
Distance and update time.
Type of incident and number of people needing assistance.
Multiple route options to choose from.
Fast, safe, and accessible routes.
Compartment pointing directly to the SOS location.

Report dangerous road sections.

Users can take photos and quickly report problematic road sections such as:

Flooding.

Landslides.

Falled trees.

Blocked roads.

Broken bridges.
Fires or dangerous power lines.

Other incidents affecting travel.

Reports will be linked to the location on the map so that the community and rescuers can proactively avoid danger or choose a more suitable route.

Operates even with unstable network connections.

Location data and reports that cannot be sent will be temporarily stored on the device and automatically synchronized when the internet connection is restored. The ability to download maps for offline use will be further expanded in future versions.

Simple and Privacy-Respecting

An Do does not require passwords, OTPs, or social media accounts. The app only shares your location directly when you actively send an SOS or use a location-requiring feature.

You can edit or delete saved personal information on your device at any time.

An Do – Travel safely, arrive safely.

Note: An Do is a tool to support location sharing and community connection; it does not replace official rescue agencies or emergency services. In dangerous situations, please contact the appropriate emergency number in your area.
