Verdict
The clearest difference is rating: Ring Sizer at 4.8 against Ring Sizer's 3.7. Ring Sizer also leads on ratings volume (35 vs 3). Ring Sizer's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Ring Sizer sells 3 in-app purchases, starting at $4.99 per 7 days and Ring Sizer sells 4 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Ring Sizer holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Ring Sizer has 35 ratings behind it against 3, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
