When a crisis hits and internet access goes down, most smartphones become almost useless. But a handful of apps are built to work without any connection at all, and they are worth having before you ever need them.
As the Israel-Iran conflict escalates following joint US-Israeli strikes on Iranian nuclear and missile facilities, and Iran disrupts global shipping through the Strait of Hormuz, people in conflict-adjacent zones are already asking this question: what actually works when the internet goes down? Here are five apps that do.
What Apps Actually Work When The Internet Goes Down?
The answer is offline-first apps, and these five are worth downloading right now.
Organic Maps is a free, ad-free GPS navigation app that works entirely without an internet connection. Built on open-source technology, it supports driving, cycling, and hiking navigation with maps refreshed twice a month. If mobile networks go down, GPS still functions via satellite, making this one of the most reliable tools in a blackout scenario.
The Offline Survival Guide is based on U.S. Army Field Manuals and covers everything from shelter-building and water purification to basic medicine and fire-making, all without needing a signal. One thing to note: the app carries ads, so keeping screen brightness low will help save battery.
Kiwix lets users download and browse entire websites, including Wikipedia, without any internet access. It uses compression technology to store large amounts of content in minimal space and displays no ads. Downloading Wikipedia’s medical edition, WikiMed, is particularly useful as it is compact and packed with health information.
Bridgefy sends messages using Bluetooth mesh networking, connecting phones within roughly 100 meters. When someone is out of range, nearby devices running the app forward messages across multiple hops. Over 12.5 million people use it globally, and Ukrainians used it during the Russian invasion to prepare for internet disruptions. One important detail: the app requires an internet connection the first time it is opened for login purposes.
PocketPal AI runs artificial intelligence language models directly on a phone, with no internet or cloud connection needed. It supports models including Phi, Gemma 2, and Qwen, and can assist with medical decisions, translations, and problem-solving offline.
Why You Should Set These Apps Up Before A Crisis, Not During One
All five apps share one common requirement: they need to be downloaded and configured before an emergency. During an active crisis, download speeds slow down, app stores may become inaccessible, and Bridgefy’s first-login step will not be possible without a connection.
Think of your phone the way you would a physical emergency kit. The time to prepare it is now, not when things fall apart.
