Verdict
Thinkie and Halo both sit at 5.0 stars, but that hides the real split: 100% of Thinkie's written reviews are positive against 50% of Halo's. Thinkie also leads on ratings volume (11 vs 2). Halo's advantage is in-app purchases (none vs 2). On price, rating, update cadence and ads there is nothing between them.
