Why would you want an app that disagrees with you all the time? Good question. Being disagreed with is definitely not a pleasant feeling. But I firmly believe that challenging our own views is a great way to keep our minds open and get closer to the truth. With that in mind, the Contradict app is designed to make disagreement as good as possible. For example, all contradictions will have Wikipedia links, so you can dive into a topic with just a tap.

Verdict
The clearest difference is in-app purchases: Contradict at none against Inspirater's 1. Contradict also leads on ads (none vs shown). Inspirater's advantage is update cadence (every 5 weeks vs every 6 months). On price, device support and iOS requirement there is nothing between them.
