# Slideory vs Calc

The clearest difference is rating: Slideory at 4.8 against Calc's 4.3. Slideory also leads on in-app purchases (none vs 6) and ratings volume (125 vs 36). Calc's advantage is device support (4 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Calc sells 6 one-off in-app purchases. Slideory asks for nothing beyond the download.

Slideory holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 125 and 36 respectively. Written reviews complicate that: 75% of Slideory's written reviews are positive against 77% of Calc's, so the app with the better star average is not the one people write more warmly about.

Slideory ships an update every 3 days, Calc weekly. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
