Verdict
JustCall and NUACOM both sit at 4.4 stars, but that hides the real split: 100% of NUACOM's written reviews are positive against 26% of JustCall's. NUACOM also leads on monetization model (free vs freemium) and iOS requirement (12.4 vs 17.0). JustCall's advantage is update cadence (weekly vs every 6 weeks) and ratings volume (1.1K vs 2). On price, rating, ads and in-app purchases there is nothing between them.
