# PDHS Allin vs PowerMath

The clearest difference is rating: PowerMath at 3.9 against PDHS Allin's 2.7. PowerMath also leads on update cadence (fortnightly vs every 2 months) and ratings volume (179 vs 39). PDHS Allin's advantage is in-app purchases (none vs 8) and ads (none vs shown). On price, device support 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. PDHS Allin asks for nothing beyond the download.

PowerMath holds the better App Store score, 3.9 against 2.7. Both are backed by a comparable volume of ratings — 39 and 179 respectively. Written reviews complicate that: 43% of PDHS Allin's written reviews are positive against 20% of PowerMath's, so the app with the better star average is not the one people write more warmly about.

PDHS Allin ships an update every 2 months, PowerMath fortnightly. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
