# My Contraction Tracker vs YUNMAI

The clearest difference is review sentiment: My Contraction Tracker at 96% against YUNMAI's 23%. My Contraction Tracker also leads on rating (4.5 vs 2.1). YUNMAI's advantage is ratings volume (400 vs 8) and update cadence (every 3 months vs every 7 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

My Contraction Tracker holds the better App Store score, 4.5 against 2.1. That said, the two scores are not equally well evidenced: YUNMAI has 400 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 96% of My Contraction Tracker's written reviews are positive against 23% of YUNMAI's.

My Contraction Tracker ships an update every 7 months, YUNMAI every 3 months. Both last shipped on November 1, 2026.
