# USCG Exam Prep vs Master

The clearest difference is review sentiment: Master at 97% against USCG Exam Prep's 50%. Master also leads on rating (4.7 vs 3.4) and in-app purchases (none vs 3). USCG Exam Prep's advantage is price (Free vs $1.99) and iOS requirement (13.4 vs 15.0). On ads and device support there is nothing between them.

USCG Exam Prep is free to download; Master costs $1.99 up front. USCG Exam Prep sells 3 one-off in-app purchases. Master asks for nothing beyond the download.

Master holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Master has 94 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 50% of USCG Exam Prep's written reviews are positive against 97% of Master's.

USCG Exam Prep ships an update every 6 months, Master fortnightly. The most recent releases landed on June 11, 2026 and September 22, 2026 respectively.
