# General Knowledge vs VibSolutions

The clearest difference is device support: VibSolutions at 3 against General Knowledge's 1. On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. General Knowledge sells 2 in-app purchases, starting at $8.99 per 7 days and VibSolutions sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
