Beartooth – A Secure Off Grid Network and Radio Communicator For Your Smartphone.


Out of pre-order status and fully available for sale.

Beartooth is a handheld device that pairs with bluetooth to your smartphone and  connects to other Beartooth devices up to 10 miles away over the 900 MHz ISM band to keep you connected when there is no cell service. It works as a long range link between you and other Beartooth users. You can use Beartooth’s app to talk, push to talk, text, use maps, and share your location securely using 256-bit AES symmetric key encryption. The Beartooth utilizes multiple hops to extend your range as you create an advanced on-the-go network to stay in touch with all members of your group. The concept of Beartooth is to provide secure communications and location sharing between Beartooth users during a “grid down” situation. You can also recharge your phone on the go using the Beartooth device itself. It has an onboard 3000mAh lithium ion battery which has enough energy to fully charge your iPhone 7 1.5 times. Unfortunately Beartooth is not compatible with non Beartooth devices therefore everyone in your group would need a Beartooth device.

  • No contracts or monthly fees associated with Beartooth, just a one time purchase for the hardware.
  • Beartooth works independently of cell service and Wi-Fi. Beartooth allows you to communicate with those around you but does not allow you to connect to the Internet.

I did have an email question and answer exchange with one of Beartooth’s representatives. What I discovered is that some of their features will be implemented later on with firmware updates, such as AES encryption and Mesh Networking.
  1. Q: Is Push to Talk communication encrypted? A: Right now Beartooth uses dynamics FHSS for security. We will be enabling AES-256.
  2. Q: Is Text messaging encrypted? A: Same as voice, Beartooth uses dynamics FHSS for security. We will be enabling AES-256.
  3. Q: Are communications (voice/text) encrypted through mesh networking? A: Once mesh is rolled out, yes.
  4. Q: Is transmitting location encrypted? A: Right now that data is protected by FHSS, we will be encrypting it in a future app update.
  5. Q: WIll there be frequent updates? A: We constantly upgrade the firmware and software and release new features.
  6. Q: Will the apps be open source? A: Right now the system is proprietary. We will consider open sourcing certain portions in the future.
  7. Q: Are all stored communications on the device encrypted? Can saved data be accessed by third party if lost? A: There is no data at rest.
  8. Q: If the device is lost can anyone use it? A: Yes, they won’t have access to any data however. Zero data at rest.
