Verdict

The call

The clearest difference is in-app purchases: DevSwipe at none against Cosmo's 4. DevSwipe also leads on review sentiment (100% vs 84%) and update cadence (weekly vs fortnightly). Cosmo's advantage is ads (none vs shown) and ratings volume (855 vs 16). On price, rating and monetization model there is nothing between them.
