# ACN/PCN Calculator vs FBOlink

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.

Both are free to download. ACN/PCN Calculator sells 10 one-off in-app purchases and FBOlink sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ACN/PCN Calculator holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: ACN/PCN Calculator has 144 ratings behind it against 14, so its average is the more settled of the two.
