Verdict

The call

The clearest difference is rating: ACN/PCN Calculator at 4.6 against FBOlink's 3.5. ACN/PCN Calculator also leads on review sentiment (45% vs 8%) and ratings volume (144 vs 14). FBOlink's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (15.6 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.
