# CalcFast vs SanpSave

The clearest difference is rating: CalcFast at 4.2 against SanpSave's 1.0. CalcFast also leads on in-app purchases (none vs 2) and ratings volume (21 vs 1). SanpSave's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (16.0 vs 27.1). On price, ads and device support there is nothing between them.

Both are free to download. SanpSave sells 2 in-app purchases, starting at $1.99 per month. CalcFast asks for nothing beyond the download.

CalcFast holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: CalcFast has 21 ratings behind it against 1, so its average is the more settled of the two.

CalcFast ships an update every 2 months, SanpSave fortnightly. The most recent releases landed on November 1, 2026 and October 28, 2026 respectively.
