Verdict
The clearest difference is rating: Atomify at 4.5 against BioViewer's 1.0. Atomify also leads on review sentiment (75% vs 33%) and ratings volume (8 vs 1). BioViewer's advantage is update cadence (every 9 days vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.
