# NSCA CSCS Mastery vs RepOne Personal

The clearest difference is rating: NSCA CSCS Mastery at 4.6 against RepOne Personal's 3.6. NSCA CSCS Mastery also leads on update cadence (fortnightly vs every 2 months) and ratings volume (97 vs 16). RepOne Personal's advantage is in-app purchases (none vs 2) and review sentiment (25% vs 17%). On price, ads and device support there is nothing between them.

Both are free to download. NSCA CSCS Mastery sells 2 in-app purchases, starting at $11.99 per month. RepOne Personal asks for nothing beyond the download.

NSCA CSCS Mastery holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: NSCA CSCS Mastery has 97 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 17% of NSCA CSCS Mastery's written reviews are positive against 25% of RepOne Personal's, so the app with the better star average is not the one people write more warmly about.

NSCA CSCS Mastery ships an update fortnightly, RepOne Personal every 2 months. The most recent releases landed on October 12, 2026 and October 5, 2026 respectively.
