Both are free to download. 8 sells 10 one-off in-app purchases and Opti Train sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Opti Train holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 3 and 3 respectively.
