# NCTest vs PowerMath

The clearest difference is in-app purchases: NCTest at none against PowerMath's 8. NCTest also leads on ads (none vs shown). PowerMath's advantage is update cadence (fortnightly vs every 2 months) and ratings volume (179 vs 3). On price, rating and iOS requirement there is nothing between them.

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

PowerMath holds the better App Store score, 3.9 against 3.7. That said, the two scores are not equally well evidenced: PowerMath has 179 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 0% of NCTest's written reviews are positive against 20% of PowerMath's.

NCTest ships an update every 2 months, PowerMath fortnightly. The most recent releases landed on October 7, 2026 and October 14, 2026 respectively.
