Verdict

The call

Number Sum and Alpha both sit at 4.6 stars, but that hides the real split: 100% of Alpha's written reviews are positive against 21% of Number Sum's. Alpha also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Number Sum's advantage is ratings volume (2.3K vs 3) and iOS requirement (12.5 vs 26.6). On price, rating, update cadence and in-app purchases there is nothing between them.
