# Sheet1Calc vs 電卓

The clearest difference is in-app purchases: Sheet1Calc at none against 電卓's 3. Sheet1Calc also leads on ads (none vs shown). 電卓's advantage is update cadence (every 6 days vs every 5 weeks) and iOS requirement (17.0 vs 26.0). On price and device support there is nothing between them.

Both are free to download. 電卓 sells 3 one-off in-app purchases. Sheet1Calc asks for nothing beyond the download.

Sheet1Calc ships an update every 5 weeks, 電卓 every 6 days. Both last shipped on November 5, 2026.
