# Riff vs MD Calculator

The clearest difference is rating: MD Calculator at 4.5 against Riff's 2.0. MD Calculator also leads on review sentiment (60% vs 21%) and ratings volume (79 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Riff sells 5 in-app purchases, starting at $0.99 per month and MD Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

MD Calculator holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: MD Calculator has 79 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 21% of Riff's written reviews are positive against 60% of MD Calculator's.
