Verdict

The call

The clearest difference is review sentiment: Perfusion Mind at 100% against Noji's 64%. Perfusion Mind also leads on ads (none vs shown) and rating (5.0 vs 4.6). Noji's advantage is ratings volume (14K vs 5) and update cadence (every 8 days vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
