# Math vs WidgetCal

The clearest difference is ads: WidgetCal at none against Math's shown. Math's advantage is update cadence (every 3 days vs every 32 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Math sells 1 one-off in-app purchase and WidgetCal sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Math ships an update every 3 days, WidgetCal every 32 months. The most recent releases landed on August 18, 2026 and August 27, 2026 respectively.
