The clearest difference is rating: +Aura at 5.0 against Cortisol Index's 3.0. +Aura also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.6). Cortisol Index's advantage is ratings volume (4 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
