Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Cosmo sells 4 in-app purchases, starting at $12.99 per month. DevSwipe asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.8 for Cosmo against 4.9 for DevSwipe. That said, the two scores are not equally well evidenced: Cosmo has 855 ratings behind it against 16, so its average is the more settled of the two. Written reviews are what separate them: 84% of Cosmo's written reviews are positive against 100% of DevSwipe's.
Cosmo ships an update fortnightly, DevSwipe weekly. The most recent releases landed on October 23, 2026 and October 1, 2026 respectively.
