Verdict

The call

CalcRx and PTCB both sit at 4.7 stars, but that hides the real split: 100% of CalcRx's written reviews are positive against 45% of PTCB's. PTCB's advantage is update cadence (every 2 weeks vs every 10 months) and ratings volume (557 vs 15). On price, rating, ads and in-app purchases there is nothing between them.
