Verdict

The call

SonLerni and Capsele both sit at 5.0 stars, but that hides the real split: 100% of SonLerni's written reviews are positive against 43% of Capsele's. SonLerni also leads on update cadence (weekly vs every 3 weeks) and ratings volume (10 vs 1). Capsele's advantage is ads (none vs shown). On price, rating, in-app purchases and monetization model there is nothing between them.
