Premom’s Origin Story
After starting Easy Healthcare Corporation (EHC) in 2013, and growing it into one of the top online personal and healthcare solution providers, co-founders Sherry Liu and Li Zou founded Premom in 2017, and they have been innovating ever since.
- 2018: Premom launched its revolutionary ovulation test digital reader.
- 2019: Premom hit half a million downloads and the company brought the first quantitative ovulation test to the US market.
- 2020: 10,000 users sign up for Premom’s new 9-Cycle Money-Back Guarantee Program within its first 30 days, and Premom launches the first data-based virtual fertility consultation service through its app.
- 2021: Premom Premium launches with a free hormone testing kit, physician-level cycle reporting, and professional services for a more holistic fertility picture.
The Premom App
Premom is an innovative fertility app designed to help women achieve pregnancy naturally and quickly. The first of its kind, it integrates biotech, medical research and artificial intelligence technology to give each user an accurate, precise and holistic look at their ovulation cycle, period and basal body temperature fluctuation. This helps users understand their unique cycle patterns and learn their most fertile days.
The data that the Premom app collects optimizes for personalized solutions and services for every woman. Users receive the most insightful knowledge on when they ovulate (the most important factor when trying to get pregnant) and have access to professional guidance along their journey to pregnancy.
The Premom Difference
One in six families* experience difficulties conceiving a baby. Until Premom, fertility apps lacked smart technology, which led to inaccurate predictions of fertile windows and a guessing game that made the process of conceiving inefficient.
Born out of the need to solve issues women face in the reproductive health sector, Premom presents the first intelligent digital reader and AI-powered algorithm capable of quantifying data from three real biomarkers: ovulation tests, basal body temperature and period. It gives real-time predictions and a comprehensive view of hormone changes and cycle progression on one simple chart. Premom is a gamechanger for women needing straightforward, quick, affordable and accurate reproductive solutions.
