PumpKin: Breast Milk Tracker

Track pumps, feeds, and your freezer stash with a partner. Built by PhD human milk researchers who are also parents. Completely free, no ads or subscriptions.

PumpKin is a free pumping tracker and breast milk stash manager for parents who pump. No ads, no subscriptions, just one calm place for milk, feeds, and family.

TRACK EVERY PUMP

• Log sessions in seconds: volume, duration, left and right side, and notes
• Start a pump timer or add a session after the fact
• Drag to split output between sides and see how each side performs
• Optional Milk Measure: estimate volume from a photo of your bottle, always with your consent

KNOW YOUR STASH

• Keep a clear fridge and freezer inventory and always see what to use first
• Freshness windows based on published CDC storage guidance, with separate clocks for fresh and thawed milk
• Forecast how many days of milk you have left at your baby's pace
• Follow every batch from pump to bottle, freezer, feed, donation, or discard

UNDERSTAND YOUR SUPPLY

• Supply trends over 7, 30, and 90 days
• Totals, time, and storage views with per session averages
• Spot patterns early, before milk gets wasted

FEED AND PREP

• Log breastfeeding and bottle feeds alongside pumping
• Prepare bottles for later and keep the plan visible to everyone
• Local reminders support your pumping rhythm and your stored milk routine

SHARE THE MENTAL LOAD

• Invite a partner or caregiver to your household
• Partners can help log pumps and feeds; cheerleaders can follow along, view only
• Your data stays private: it is visible only to the people you invite

WHY PUMPKIN IS FREE PumpKin is built by PhD researchers in human milk, microbiology, and biology who are also parents. We are a public benefit corporation, and our work is supported by research grants rather than app sales, so PumpKin stays completely free: no ads, no subscriptions, no paid plans, and no locked features.

PumpKin is an organizational and educational tool. It is not a medical device and does not replace professional medical advice. Storage guidance reflects published CDC recommendations; always follow the advice of your care team.
