Useful Android Apps

This is my first post here in 2026, and unfortunately, we're struggling to survive! So today I'm sharing apps that could make a real difference in tough situations, whether for mental support or emergencies.

As I write this post (2026/01/30), over 20 days have passed since the 2025–2026 Iranian protests and the 2026 internet blackout in Iran . During that time, the entire country was reduced to a nationwide intranet through ISPs, with no access to the global internet. For 14 days, we had no access to anything in Tehran (some cities experienced even longer outages), and even now, internet access has not returned to normal. We are also under the threat of a possible war.

A few days ago, I decided to gather the information I have collected over the years and write a post about useful Android apps, most of which work offline. You can also view this list in the Telegram channel post .

Why Android ? Because it is widely accessible and highly flexible — it offers far more OS-level freedom than iOS, and APK files can be easily installed from various sources such as GitHub or F-Droid. Additionally, by unlocking the bootloader and rooting the device, one can gain capabilities comparable to those of a full PC.

I mainly provide Android links, along with official website links (🔗) so you can check whether versions exist for other operating systems. Even if the same app isn't available on other platforms, you can name it and search for similar alternative apps on your preferred operating system.
All apps listed here were hand-picked and personally tested by me over the years — they are NOT AI-generated.
The list is long, but in critical situations, even one of these apps could be life-saving.
Some apps have full/unlocked versions available from third-party sources. If you have an Iran IP and don't mind using jailbroken/cracked apps, you can access full versions from https://farsroid.com or https://soft98.ir .
I focused on apps that work offline. If you have enough storage and think you might need them someday, download and keep them.
Some apps require plugins or initial setup — after installing, run them at least once and explore their settings to ensure everything works properly offline.
Many of these apps are more important than they may seem at first glance.
Some apps are intended for advanced or power users. If you don't understand an app or feel uncomfortable with it, it's better to skip it or use it with caution.
