# CPR Nutrition vs Custom Rings

The clearest difference is rating: CPR Nutrition at 5.0 against Custom Rings's 4.4. CPR Nutrition also leads on review sentiment (100% vs 75%). Custom Rings's advantage is monetization model (freemium vs subscription) and update cadence (every 4 days vs every 9 days). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. CPR Nutrition sells 1 in-app purchase, starting at $29.99 per year and Custom Rings sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CPR Nutrition holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Custom Rings has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of CPR Nutrition's written reviews are positive against 75% of Custom Rings's.

CPR Nutrition ships an update every 9 days, Custom Rings every 4 days. The most recent releases landed on October 7, 2026 and October 28, 2026 respectively.
