Verdict
The clearest difference is review sentiment: Ring Sizer AI at 100% against Ring Sizer's 33%. Ring Sizer AI also leads on rating (5.0 vs 4.7). Ring Sizer's advantage is ads (none vs shown) and ratings volume (50 vs 3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Ring Sizer sells 4 in-app purchases, starting at $4.99 per 7 days and Ring Sizer AI sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Ring Sizer AI holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Ring Sizer has 50 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 33% of Ring Sizer's written reviews are positive against 100% of Ring Sizer AI's.
