Verdict

The call

The clearest difference is price: Effectrix at Free against Chomplr's $4.99. Effectrix also leads on rating (4.7 vs 4.0) and review sentiment (67% vs 56%). Chomplr's advantage is update cadence (every 3 days vs every 4 months) and device support (3 vs 1). On ratings volume, ads and in-app purchases there is nothing between them.
