# CalcFast vs Calculator ×

The clearest difference is in-app purchases: CalcFast at none against Calculator ×'s 4. CalcFast also leads on ads (none vs shown). Calculator ×'s advantage is rating (4.5 vs 4.2) and ratings volume (143 vs 20). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. Calculator × sells 4 in-app purchases, starting at $4.99 per year. CalcFast asks for nothing beyond the download.

Calculator × holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Calculator × has 143 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 78% of CalcFast's written reviews are positive against 73% of Calculator ×'s, so the app with the better star average is not the one people write more warmly about.

CalcFast ships an update every 2 months, Calculator × every 3 months. The most recent releases landed on October 13, 2026 and October 17, 2026 respectively.
