# SPL vs Units Calculator

The clearest difference is in-app purchases: Units Calculator at none against SPL's 1. SPL's advantage is ads (none vs shown) and iOS requirement (9.3 vs 15.0). On price and device support there is nothing between them.

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