Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
Both ship on a similar rhythm, roughly every 2 months. Both last shipped on October 13, 2026.
