The Spy
Read full descriptionHide full description
Identify the spy! One or more players are spies and the others will have to find them. Every player who isn't a spy will be given the same word - the spies won't know that word. Then, every player has to say a word (the spies too) and each and every player will have to find out, who is a spy (doesn't know the word) and who is a normal player. When the spy finds out the word before the players can identify the spy, they win. Otherwise the players win.

Verdict
The clearest difference is update cadence: The Spy at every 4 weeks against Mental Chronometry's every 42 months. Mental Chronometry's advantage is iOS requirement (15.6 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
