# Fraction Calculator vs iDrawlix Mobile

The clearest difference is rating: Fraction Calculator at 4.7 against iDrawlix Mobile's 1.0. Fraction Calculator also leads on update cadence (monthly vs every 10 months) and ratings volume (174 vs 1). iDrawlix Mobile's advantage is review sentiment (100% vs 75%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fraction Calculator sells 5 in-app purchases, starting at $4.99 per month and iDrawlix Mobile sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Fraction Calculator holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Fraction Calculator has 174 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Fraction Calculator's written reviews are positive against 100% of iDrawlix Mobile's, so the app with the better star average is not the one people write more warmly about.

Fraction Calculator ships an update monthly, iDrawlix Mobile every 10 months. Both last shipped on November 2, 2026.
