Verdict
The clearest difference is rating: Arm Care at 4.9 against 4APP Sports's 4.4. Arm Care also leads on ratings volume (3K vs 198) and update cadence (weekly vs every 3 weeks). On price, ads, 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. Arm Care sells 10 in-app purchases, starting at $11.99 per month and 4APP Sports sells 9 in-app purchases, starting at $99.00 per month. Whichever you choose, the download price is not the number that matters.
Arm Care holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Arm Care has 3K ratings behind it against 198, so its average is the more settled of the two. Written reviews point the same way: 74% of Arm Care's written reviews are positive against 65% of 4APP Sports's.
Arm Care ships an update weekly, 4APP Sports every 3 weeks. Both last shipped on November 3, 2026.
