# Fractio vs PowerOne calculator

The clearest difference is rating: PowerOne calculator at 4.6 against Fractio's 3.2. PowerOne calculator also leads on ratings volume (806 vs 11) and update cadence (every 3 months vs every 9 months). Fractio's advantage is in-app purchases (none vs 2) and review sentiment (67% vs 50%). On price, ads and device support there is nothing between them.

Both are free to download. PowerOne calculator sells 2 in-app purchases, starting at $2.99 per month. Fractio asks for nothing beyond the download.

PowerOne calculator holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: PowerOne calculator has 806 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 67% of Fractio's written reviews are positive against 50% of PowerOne calculator's, so the app with the better star average is not the one people write more warmly about.

Fractio ships an update every 9 months, PowerOne calculator every 3 months. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
