# Re vs 設計用電卓

The clearest difference is ads: Re at none against 設計用電卓's shown. 設計用電卓's advantage is update cadence (every 3 days vs every 3 weeks) and iOS requirement (12.0 vs 14.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Re ships an update every 3 weeks, 設計用電卓 every 3 days. Both last shipped on October 10, 2026.
