# MPM vs 声线

The clearest difference is in-app purchases: MPM at none against 声线's 18. MPM also leads on review sentiment (100% vs 66%) and rating (5.0 vs 4.6). 声线's advantage is update cadence (every 2 weeks vs monthly) and ratings volume (12 vs 2). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. 声线 sells 18 in-app purchases, starting at $0.99 per month. MPM asks for nothing beyond the download.

MPM holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: 声线 has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of MPM's written reviews are positive against 66% of 声线's.

MPM ships an update monthly, 声线 every 2 weeks. The most recent releases landed on September 17, 2026 and September 25, 2026 respectively.
