Verdict
The clearest difference is in-app purchases: CorePendium at none against STAT EM's 2. CorePendium also leads on ratings volume (1.4K vs 6) and update cadence (monthly vs every 3 months). STAT EM's advantage is review sentiment (100% vs 67%) and chart position (#166 vs unranked). On price, rating, ads and device support there is nothing between them.

Both are free to download. STAT EM sells 2 in-app purchases, starting at $0.99 per month. CorePendium asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.9 for CorePendium against 5.0 for STAT EM.

Written reviews are what separate them: 67% of CorePendium's written reviews are positive against 100% of STAT EM's.
