# 年齢・計算 vs PaperCode

The clearest difference is ads: PaperCode at none against 年齢・計算's shown. PaperCode also leads on update cadence (every 3 weeks vs every 10 months). 年齢・計算's advantage is iOS requirement (14.0 vs 16.0). 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.

年齢・計算 ships an update every 10 months, PaperCode every 3 weeks. The most recent releases landed on September 22, 2026 and July 25, 2026 respectively.
