Comments on CorpsGuide: USMC Tools for Android

★★★★★ Arley Rojas-Huffman · Jul 3, 2025
Just a good app telling you everything to know about the usmc
★★★★★ Jeff Hinschberger · Aug 1, 2025
5 stars just for Mar admin functionality alone.
★★★★☆ Dakota Castle · Dec 16, 2025
Would appreciate it if the app had all the medals and ribbons in the rack builder. Kind of a redundant feature if it's incomplete.
★★★★☆ Matthew Mangiacapra · Nov 9, 2025
Decent app but I think it would be better if you gave what specific items were on uniforms
★★★★★ Jerhdin · Feb 12, 2026
Tons of good information, and amazingly fast response time and app corrections if you find something wrong or needs added. Recommend this app.
