Verdict

The call

Chatwork and Green both sit at 4.5 stars, but that hides the real split: 45% of Green's written reviews are positive against 16% of Chatwork's. Green also leads on monetization model (free vs free with in-app purchases) and update cadence (weekly vs fortnightly). Chatwork's advantage is ratings volume (57K vs 1.2K). On price, rating, ads and in-app purchases there is nothing between them.
