BLU is a cloud based dive logging App with the only Dive Site Directory that has detailed markers and integrated weather. Share your logs with your friends, family and the world, and host Dive Log Watch Parties remotely controlling your logs on your Smart TV or big screen directly from the App.

BLU is FREE to use, and our paid Pioneer program, offers unique tiny QR tags that bind with your equipment. In the event your equipment is lost or stolen, our tags will help you recover it without having to use old fashioned sticky labels exposing personal details like your phone number and address.

We have over 20k dive sites ready for you to map to logs imported from your dive computer. So what are you waiting for? Download BLU today and help build a better dive site directory for everyone. We're just getting started and we need to spread the word about BLU; so when you signup we ask you to choose from one of the stores near your location. If the store has yet to be fully enrolled it receives a notification. Don't worry your personal details are safe as dive stores can only reach out to you via the App.

In future we hope to host dive expeditions and more Citizen Science Projects from all over the world, so if you're looking for support to help promote and highlight your next expedition, please sign-up and use our integrated messaging to speak to Customer Service.

Game changer

I came across this app and love all the features it offers. The built in mapping system allows you to navigate an entire list of diving sites over the world while being able to book dives through professional stores. I am also able to invite my friends to join dives, that is a real game changer. Well done to the app dev team!
