# ビジネス電卓 vs AIメールくん

The clearest difference is ads: AIメールくん at none against ビジネス電卓's shown. AIメールくん also leads on update cadence (every 9 days vs every 24 months). ビジネス電卓's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price and in-app purchases there is nothing between them.

Both are free to download. ビジネス電卓 sells 1 in-app purchase, starting at $0.99 per month and AIメールくん sells 1 in-app purchase, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ビジネス電卓 ships an update every 24 months, AIメールくん every 9 days. Both last shipped on November 3, 2026.
