# 電卓 vs Voice

The clearest difference is ads: 電卓 at none against Voice's shown. Voice's advantage is update cadence (every 2 weeks vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

電卓 ships an update monthly, Voice every 2 weeks. Both last shipped on October 30, 2026.
