Verdict
The clearest difference is update cadence: RadOnc Reference at every 2 months against BED Calculator's every 41 months. RadOnc Reference also leads on ratings volume (45 vs 3) and iOS requirement (6.0 vs 16.6). BED Calculator's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 80%). On price, ads, in-app purchases and monetization model there is nothing between them.
