# FastCast. vs OptoFitting

The clearest difference is review sentiment: OptoFitting at 100% against FastCast.'s 21%. OptoFitting also leads on rating (5.0 vs 3.8) and ads (none vs shown). FastCast.'s advantage is ratings volume (282 vs 1) and monetization model (ad-supported vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. FastCast. sells 3 in-app purchases, starting at $0.99 per 7 days and OptoFitting sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

OptoFitting holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: FastCast. has 282 ratings behind it against 1, so its average is the more settled of the two.
