# QuickCalculator vs 拼音

The clearest difference is in-app purchases: 拼音 at none against QuickCalculator's 2. 拼音 also leads on ads (none vs shown). QuickCalculator's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 17.0). On price there is nothing between them.

Both are free to download. QuickCalculator sells 2 in-app purchases, starting at $0.99 per year. 拼音 asks for nothing beyond the download.
