# My Knowledge Base vs Formula Lab

The clearest difference is ads: My Knowledge Base at none against Formula Lab's shown. Formula Lab's advantage is iOS requirement (13.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. My Knowledge Base sells 1 one-off in-app purchase and Formula Lab sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
