# Calculator Smart vs GraphCalcPro2Go

Calculator Smart and GraphCalcPro2Go both sit at 4.7 stars, but that hides the real split: 80% of GraphCalcPro2Go's written reviews are positive against 36% of Calculator Smart's. GraphCalcPro2Go also leads on ads (none vs shown). Calculator Smart's advantage is ratings volume (494 vs 40) and device support (6 vs 3).
