# Conversion Calculator vs ServiceVault

The clearest difference is ratings volume: Conversion Calculator at 157 against ServiceVault's 3. ServiceVault's advantage is rating (5.0 vs 4.8). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Conversion Calculator sells 1 one-off in-app purchase and ServiceVault sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ServiceVault holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Conversion Calculator has 157 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
