# SnapCalc vs Solvio

The clearest difference is rating: SnapCalc at 4.2 against Solvio's 2.7. SnapCalc also leads on update cadence (monthly vs every 16 months) and ratings volume (41K vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SnapCalc sells 9 in-app purchases, starting at $1.99 per 7 days and Solvio sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SnapCalc holds the better App Store score, 4.2 against 2.7. That said, the two scores are not equally well evidenced: SnapCalc has 41K ratings behind it against 3, so its average is the more settled of the two.

SnapCalc ships an update monthly, Solvio every 16 months. The most recent releases landed on October 13, 2026 and October 2, 2026 respectively.
