# Computer Science Dictionary vs Spider AI

The clearest difference is device support: Computer Science Dictionary at 3 against Spider AI's 1. Computer Science Dictionary also leads on iOS requirement (13.0 vs 26.2). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Computer Science Dictionary sells 1 one-off in-app purchase and Spider AI sells 2 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
