Verdict

The call

Brainscape and Cogni both sit at 4.8 stars, but that hides the real split: 83% of Brainscape's written reviews are positive against 36% of Cogni's. Brainscape also leads on ratings volume (22K vs 1.7K) and chart position (#177 vs unranked). Cogni's advantage is update cadence (every 9 days vs every 3 weeks). On price, rating, ads and in-app purchases there is nothing between them.
