Cry Detector is an app for iOS devices and the Apple Watch that is designed to detect your baby's cry and keep him calm until you arrive. It listen for sounds strong enough to be considered as cries, filtering breathing or other lower sounds, and when the sensor is triggered, a lullaby or a recorded audio of your own will be played. Select between 4 different and famous lullabies, or record your own voice! Remember, your voice is the optimal sound to calm your baby! Play the lullabies at any time with the play button, or activate the detector just pressing the central listening button. The noise level can be checked in the lower coloured band: green for filtered sounds, and red for the strong ones. And if you have an Apple Watch, you will be able to see the status remotely!

Verdict
The clearest difference is in-app purchases: shenqiwei at none against Cry Detector's 1. shenqiwei also leads on update cadence (every 5 days vs every 10 months). Cry Detector's advantage is iOS requirement (9.0 vs 11.0). On price, ads and device support there is nothing between them.
