Verdict

The call

The clearest difference is ads: Cosmo at none against DataCamp's shown. Cosmo also leads on review sentiment (84% vs 72%). DataCamp's advantage is ratings volume (4.8K vs 859) and device support (3 vs 1). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. DataCamp sells 10 in-app purchases, starting at $35.00 per month and Cosmo sells 4 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.8 for DataCamp against 4.8 for Cosmo. That said, the two scores are not equally well evidenced: DataCamp has 4.8K ratings behind it against 859, so its average is the more settled of the two. Written reviews are what separate them: 72% of DataCamp's written reviews are positive against 84% of Cosmo's.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
