Mesh Messaging Apps: Lifesavers During Internet Outages

In an era where internet access and mobile signals seem as essential as electricity, communicating without them feels almost impossible.
However, during special situations — such as large-scale network outages, natural disasters, or being in remote areas and crowded festivals — Mesh messaging apps can come to the rescue.

These apps are based on peer-to-peer (P2P) technology and use Bluetooth or Wi-Fi Direct to connect nearby devices into a decentralized network.
Messages are then transmitted directly from one user to another, without any need for the internet or central servers.

 

Popular Mesh Messaging Apps

  • BitChat: The latest decentralized messenger introduced in July 2025 by Jack Dorsey, co-founder of Twitter/X. It’s open-source but has shown some security vulnerabilities according to experts.
  • Bridgefy: With over 12 million users, it’s one of the most popular options, operating over Bluetooth. However, the free version contains many ads.
  • Briar: Considered one of the most secure apps, supporting the Tor anonymous network. It’s open-source but has limitations, such as no file sharing and availability only on Android.
  • White Mouse: A new app featuring disappearing messages and anti-screenshot protection. Currently Android-only, but versions for other platforms are in development.

 

Limitations and Security Concerns

Mesh messaging apps are not replacements for daily messengers like WhatsApp or Telegram.
Their effective range is typically around 100 meters in open areas, and their performance depends on the number of nearby users.
Continuous use of Bluetooth and Wi-Fi can also drain battery power more quickly.

Cybersecurity experts warn users not to rely solely on the apps’ security claims.
Only open-source projects that have undergone independent security audits are considered trustworthy.
Therefore, these apps are not recommended for confidential or sensitive communication.

 

Final Thoughts

Mesh apps can be viewed as digital first-aid kits — tools that should be installed and ready in advance for emergencies, travel, or situations where internet access might be disrupted.
Alongside these apps, having a backup communication device such as a real walkie-talkie is also a smart idea.
