Verdict

The call

The clearest difference is ads: Check at none against Chillax's shown. Check also leads on update cadence (weekly vs every 2 months). Chillax's advantage is monetization model (free vs freemium) and ratings volume (10 vs 1). On price, rating, review sentiment and in-app purchases there is nothing between them.
