# Arm Care vs A.M.P.

The clearest difference is in-app purchases: A.M.P. at none against Arm Care's 11. Arm Care's advantage is ratings volume (3K vs 3) and update cadence (every 9 days vs every 3 weeks). On price, rating, ads and device support there is nothing between them.

Both are free to download. Arm Care sells 10 in-app purchases, starting at $11.99 per month. A.M.P. asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Arm Care against 5.0 for A.M.P.. That said, the two scores are not equally well evidenced: Arm Care has 3K ratings behind it against 3, so its average is the more settled of the two.

Arm Care ships an update every 9 days, A.M.P. every 3 weeks. The most recent releases landed on September 27, 2026 and September 11, 2026 respectively.
