Verdict

The call

The clearest difference is ads: PipeFabAR at none against Calculator +'s shown. PipeFabAR also leads on rating (5.0 vs 4.6). Calculator +'s advantage is update cadence (every 4 days vs every 3 months) and ratings volume (10K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
