Verdict
The clearest difference is review sentiment: DrDrugs at 67% against Compendium's 25%. DrDrugs also leads on rating (4.5 vs 4.0) and ratings volume (35 vs 1). Compendium's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 4 months). On price, in-app purchases, monetization model and device support 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. Compendium sells 4 in-app purchases, starting at $3.49 per month and DrDrugs sells 6 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
DrDrugs holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: DrDrugs has 35 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 25% of Compendium's written reviews are positive against 67% of DrDrugs's.
Compendium ships an update every 3 weeks, DrDrugs every 4 months. Both last shipped on October 29, 2026.
