Thanks for using USCG Prep — keep the feedback coming! ### 1.0.2 — 2026-07-25 Minor bug fixes and performance improvements. Thanks for using USCG Prep — keep the feedback coming! ### 1.0.1 — 2026-07-13 This update is packed with improvements based on your feedback: • Randomized study order — questions within each module now appear in a fresh order every session, so you're always actively recalling, not memorizing sequence. • Topic filters — narrow any module down to exactly what you want to drill (e.g. just Lights & Shapes within the Rules module). • Properly rendered math — formulas in hints and explanations now display as real mathematical notation instead of raw code. • COLREGS module now available for study. • Fixed Module Accuracy stats so they reflect only your selected license. Reminder: you can view and switch your target license anytime under Profile → Target License. Your progress is saved separately per license. Thanks for the great feedback — keep it coming! ### 1.0 — 2026-05-03 No release notes. ## Apps similar to USCG Prep | App | Rating | Price | Category | | --- | --- | --- | --- | | [Captain Sherry Classroom](https://appshunter.io/ios/app/captain-sherry-classroom/id6744043786) | — | Free | Education | | [USCG Exam Prep](https://appshunter.io/ios/app/uscg-exam-prep/id1579535924) | 3.4 (10) | Free | Education | | [Coast Guard Exams](https://appshunter.io/ios/app/coast-guard-exams/id6755545325) | 4.0 (3) | Free | Education | | [USCG Captain Exam Prep 2026](https://appshunter.io/ios/app/uscg-captain-exam-prep-2026/id6774155074) | 1.0 (1) | Free | Education | | [USCG OUPV Exam Prep 2026](https://appshunter.io/ios/app/uscg-oupv-exam-prep-2026/id6759241913) | 3.0 (1) | Free | Education | | [HomeSchoolLog](https://appshunter.io/ios/app/homeschoollog/id6763504025) | — | Free | Education | ## More apps by Serhan Cetin - [VisArch: AI Render & Staging](https://appshunter.io/ios/app/visarch-ai-render-and-staging/id6755615468) - [Handover AI: Marine GPT](https://appshunter.io/ios/app/handover-ai-marine-gpt/id6758022888) - [Denizcilik Akademisi](https://appshunter.io/ios/app/denizcilik-akademisi/id6759873256) - [Terminal - SSH Client](https://appshunter.io/ios/app/terminal-ssh-client/id6760950395) - [Coolify Manager](https://appshunter.io/ios/app/coolify-manager/id6760950561) - [WiFi File Transfer: From PC](https://appshunter.io/ios/app/wifi-file-transfer-from-pc/id6760991506) All apps by Serhan Cetin: https://appshunter.io/developer/1788346221 ## Related topics [uscg exam prep](https://appshunter.io/ios/topics/uscg-exam-prep) · [stcw bst exam prep 2026](https://appshunter.io/ios/topics/stcw-bst-exam-prep-2026) · [uscg oupv exam prep 2026](https://appshunter.io/ios/topics/uscg-oupv-exam-prep-2026) · [captain license](https://appshunter.io/ios/topics/captain-license) · [euro boat master](https://appshunter.io/ios/topics/euro-boat-master) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
