Verdict

The call

The clearest difference is in-app purchases: BRAIN at none against Mental Age Test's 3. BRAIN also leads on ads (none vs shown) and rating (4.7 vs 4.2). Mental Age Test's advantage is update cadence (every 2 months vs every 27 months) and ratings volume (3K vs 3). On price and device support there is nothing between them.
