With this information in mind when setting up a study plan for the test.. I have been able to prepare enough to pick up Hm1 in 5.5yrs. This app does exactly what I need it to in order to prepare. No extra info. Just the basics. It works for what it was meant to do. ### 5/5 — Great *2017-10-18, version 1.2.8* It's perfect. ### 5/5 — Awesome and current! *2016-02-29, version 1.0* Great app. More importantly, the NAVADMIN and Instruction are linked for further reference. AWESOME! ### 5/5 — This app got me from Private to General! *2015-11-06, version 1.0* I came into the Navy as a private. After 30 years, I wondered, "why haven't I gotten a promotion?" Well, thanks to this app, I am now a general. Thank god (and the United States Government) for this app! ### 5/5 — Great idea *2015-11-06, version 1.0* Good info to know. ### 5/5 — Great Resource *2015-11-06, version 1.0* Great resource to double check your FMS and see what you're "going into the exam" with. V/R, MA1 Washington NRD Michigan @ Navy Recruiter Washington ### 4/5 — Great but... *2016-08-31, version 1.2.1* Great app but I have not seen any updates for the next cycle... Final multiple not coming up for last cycle in order to know about how much you may need to score for the next exam!!! ### 4/5 — CCC *2015-11-09, version 1.0* I like the app. The only thing I don't like is the PMA scale. It wouldn't let me put in my actual PMA. As soon as I took my finger off the circle it bumped either up or down. I tried several times to make certain it was not me. I would like to see either a type in option or a +/- to adjust. ### 3/5 — Needs fixing *2021-01-27, version 3.0* Smart and needed app. However, when inputting RSCA there is no way to put a decimal point. If that was fixed it would be perfect. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
