Read full descriptionHide full description
Pearl Jar is a personal birth log for midwives, obstetricians, health care assistants, nurses, and students. Every birth you register becomes a pearl in your jar, giving you a visual overview of your midwifery journey. After a birth, you can quickly note the essentials: gender, birth type, your role, place, and year. Optional details such as weight category and zodiac sign can be added when you like. Twins and multiple births are handled as connected groups, so your log stays easy to scan. What you can use Pearl Jar for β’ Register births in seconds while the experience is still fresh β’ Watch your midwifery journey gather as pearls on the home screen β’ Get statistics on gender, birth type, places, roles, and more β’ Save private reflections that are only for you β’ Share milestones with colleagues you trust β’ Find and follow other midwives in a closed feed Built with respect for your work Pearl Jar is designed with confidentiality and data minimization in mind. The app uses birth year instead of full dates, categorical weight instead of exact numbers, and private notes are never shared in the feed. You decide what to share, and with whom. For remembering and reflecting Whether you're in practice or training, Pearl Jar gives you a place to collect your experiences. Pearl Jar is a personal practice log. It does not replace medical advice, clinical record-keeping, or your employer's systems.
