PumpKin: Breast Milk Tracker

PumpKin is a free pumping tracker and breast milk stash manager for parents who pump. No ads, no subscriptions, no one-time payment, just one 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 storage bag, always with your consent

KNOW YOUR STASH
- Keep a clear fridge and freezer inventory and always see what to use first
- Optional storage suggestions based on each bag's dates, where it has been kept, and the guidelines you choose
- 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
- Donating extra milk? See how milk banks work where you live, with a report ready for the bank's call

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.
