# O2X vs AFT Score Calculator

The clearest difference is rating: AFT Score Calculator at 4.8 against O2X's 4.2. AFT Score Calculator also leads on in-app purchases (none vs 2) and ratings volume (973 vs 68). O2X's advantage is ads (none vs shown) and review sentiment (66% vs 38%). On price, device support and iOS requirement there is nothing between them.

Both are free to download. O2X sells 2 in-app purchases, starting at $9.99 per month. AFT Score Calculator asks for nothing beyond the download.

AFT Score Calculator holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: AFT Score Calculator has 973 ratings behind it against 68, so its average is the more settled of the two. Written reviews complicate that: 66% of O2X's written reviews are positive against 38% of AFT Score Calculator's, so the app with the better star average is not the one people write more warmly about.

O2X ships an update every 3 weeks, AFT Score Calculator every 2 months. Both last shipped on November 3, 2026.
