# 慧音FM vs solAR

The clearest difference is in-app purchases: 慧音FM at none against solAR's 1. 慧音FM also leads on rating (5.0 vs 4.6) and iOS requirement (9.0 vs 14.0). solAR's advantage is ratings volume (2.1K vs 3) and device support (5 vs 3). On price, update cadence and ads there is nothing between them.

Both are free to download. solAR sells 1 one-off in-app purchase. 慧音FM asks for nothing beyond the download.

慧音FM holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: solAR has 2.1K ratings behind it against 3, so its average is the more settled of the two.

慧音FM ships an update every 2 months, solAR every 3 months. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
