# PowerMath vs Studdy

The clearest difference is review sentiment: Studdy at 89% against PowerMath's 20%. Studdy also leads on rating (4.8 vs 3.9) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. PowerMath sells 8 in-app purchases, starting at $1.99 per month and Studdy sells 35 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Studdy holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: Studdy has 13K ratings behind it against 179, so its average is the more settled of the two. Written reviews point the same way: 20% of PowerMath's written reviews are positive against 89% of Studdy's.

PowerMath ships an update fortnightly, Studdy every 10 days. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
