I really enjoy this app. It works great on Mac and iPhone.

Currently holding my Chiefmate unlimited oceans, this app was vital to me upgrading. I grew up using upgrade U but there is no comparison. Hammer the general modules on here till you’re making 90’s, in conjunction with lapware later on towards the end before testing and you will do just fine. Remember to test on the practice exams from the USCG website. Those exams will be very similar to the questions you will see exam day. 🫡

App works much better after the recent fix to the last mega update. I’m studying for my CM/Master Unlimited and this is my go-to app for studying. I love how it tracks your problem areas so you know what needs to be improved. Thank you for taking the time to respond to my last feedback post and fix the issue. You guys are great!!
