Linked List: Three Offline Capable Apps for Emergency Situations

I love traveling and trekking ¹. At least when riding or driving across India, you would reach a place where you don’t have an internet connection, but you want to figure something out. For example, one time, I thought a spider bit me, and my arm was swollen. We were trying to figure first aid in a remote place with not much connectivity.

For such situations, I do have some apps that have come in handy. So a list of them is my linked list this week.

Survival Manual

This is a survival manual/guide based on the public domain US Army Survival Field Manual FM 3-05.70 (FM 21-76). It is fully functional offline, which is important in the case of a catastrophe.

It’s an Open Source Android application available on FDroid and PlayStore. The content is curated on a Wiki. It’s been very useful even in urban environments.

Trail Sense

Use your Android phone’s sensors to assist with wilderness treks or survival situations. Designed for entirely offline use.

It’s a FOSS app with lots of features combined into a single app. It feels like a Swiss Army knife of small tools. It has Compass navigation, Astronomy, weather, measurement scale, small apps to measure cliff, etc. It’s available on FDroid and Playstore.

First Aid – IFRC

The official IFRC First Aid app gives instant access to the information you need to know to handle the most common first aid emergencies and safety tips for crisis situation. With interactive quizzes and simple step-by-step everyday first aid scenarios, it’s never been easier to learn first aid.

It has easy-to-follow steps in case of emergency. The App doesn’t replace the real training but helps you in situations. There was an Indian Red Cross App, but it was removed from the App store for some reason. So I have updated (2025-07-23) with the link to IFRC one.
