Verdict
The clearest difference is review sentiment: BifurcAID 3D at 100% against CathSource's 38%. BifurcAID 3D also leads on rating (5.0 vs 1.6) and monetization model (ad-supported vs paid). CathSource's advantage is ads (none vs shown) and update cadence (every 2 months vs every 12 months). On price, in-app purchases and device support there is nothing between them.
