# Calculator vs WhisperDirect

The clearest difference is in-app purchases: Calculator at none against WhisperDirect's 1. Calculator also leads on iOS requirement (15.0 vs 18.0). WhisperDirect's advantage is update cadence (every 4 days vs every 6 months). On price, ads and device support there is nothing between them.

Both are free to download. WhisperDirect sells 1 one-off in-app purchase. Calculator asks for nothing beyond the download.

Calculator ships an update every 6 months, WhisperDirect every 4 days. Both last shipped on November 8, 2026.
