Ratings and reviews

Exceedingly smooth, and works offline! Very user-friendly, and has a lot of useful widgets, like an EAOS countdown and Zulu times, and even when the next payday will arrive! It's a must have for every sailor who goes underway! Everything you wish the Navy did, but better!

Very intuitive and responsive! I've wished I had this exact app for the entirety of my Navy career. I suggest everyone whose in the Navy to download this and have it on hand as it will help you tremendously!

Great tool for US Navy Sailors! love how easy it is to use and how you can use it offline! Definitely makes life easier when deployed on a ship or the hangar you're in has no service haha
