Verdict
The clearest difference is price: SmartFriends at Free against DualBrain+ Brain Training's $1.99. SmartFriends also leads on update cadence (every 2 weeks vs every 22 months) and ratings volume (139 vs 3). DualBrain+ Brain Training's advantage is in-app purchases (none vs 10) and ads (none vs shown). On device support there is nothing between them.
