Verdict
The clearest difference is update cadence: Intern Cheat Sheet at every 4 days against Opioid Calculator's every 6 months. Intern Cheat Sheet also leads on review sentiment (100% vs 81%) and iOS requirement (14.0 vs 16.6). Opioid Calculator's advantage is chart position (#173 vs unranked) and price ($0.99 vs $2.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
