# Bluebook Exams vs PowerMath

The clearest difference is rating: PowerMath at 4.0 against Bluebook Exams's 1.4. PowerMath also leads on update cadence (every 3 weeks vs every 6 weeks) and iOS requirement (15.0 vs 18.0). Bluebook Exams's advantage is in-app purchases (none vs 8) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. PowerMath sells 8 in-app purchases, starting at $1.99 per month. Bluebook Exams asks for nothing beyond the download.
