# O'Reilly vs DataCamp

The clearest difference is in-app purchases: O'Reilly at none against DataCamp's 10. O'Reilly also leads on ads (none vs shown) and ratings volume (34K vs 4.8K). DataCamp's advantage is review sentiment (72% vs 46%) and iOS requirement (15.1 vs 18.5). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. DataCamp sells 10 in-app purchases, starting at $35.00 per month. O'Reilly asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for O'Reilly against 4.8 for DataCamp. That said, the two scores are not equally well evidenced: O'Reilly has 34K ratings behind it against 4.8K, so its average is the more settled of the two. Written reviews are what separate them: 46% of O'Reilly's written reviews are positive against 72% of DataCamp's.

O'Reilly ships an update every 2 weeks, DataCamp fortnightly. Both last shipped on September 25, 2026.
