Description
Project Monarch is an effort to leverage recent advances in tracking technology, that have enabled the development of the world’s smallest tracking devices, to track Monarch migration.
The tracking devices on the monarch butterflies transmit at the same frequency as Bluetooth which means that everyone with a smartphone is carrying around a receiver in their pocket! This revolutionary approach can potentially create the largest wildlife tracking receiver network in the world, but only if members of the public download and use the free Project Monarch app.
These data will allow scientists to track the movements of monarch butterflies in detail never previously imagined. We will see how monarchs utilize key stopping points along migratory routes and learn more about the speed and direction of migration, helping identify the most important sites for habitat conservation and restoration. Ultimately, this technology can help guide conservation planning and lead to increases in monarch populations.

App does launch on Samsung phones after you verify the EMAIL the app sends you. A reviewer named Patrick below said it was a text message they send, it is not an SMS text message to your phone, It's an email note sent to the one you enter on registration.

HOW TO FIX CRASHES (Nov 2025): App was crashing after I installed. To fix, you need to grant it location and nearby device permissions then it will open. Without those permissions granted I will never open (it should open then ask for the permission but never gets that far)

I couldn't get it to open after creating an account and logging in. It just kept crashing when trying to open it. Too bad.

Downloaded and installed app on my Samsung Android phone. Created an account and when I hit "launch" the program crashed. Even if you log out and hit launch again it still crashes. No contact information on who might help resolve this issue.
