Pain comes in many forms during the latter stages of pregnancy, but the source of an expectant mother’s discomfort isn’t always clear. Is it gas, urinary irritation, or just normal contractions?

Bloomlife aims to remove this uncertainty with its new pregnancy wearable. Worn on the belly during the third trimester, the device utilizes a sensor to monitor contraction patterns and better detect how a woman’s body is preparing for labor.

Available for both iOS and Android, the pregnancy wearable starts at $149 on Bloomlife’s website.
