MamaFlow - Simple Pumping Tracking Pumping is hard enough without juggling spreadsheets or forgetting when you last pumped. MamaFlow is a straightforward app that helps you log sessions, set reminders, and see your progress over time. Made by a parent who knows the struggle. What you can do: Track your sessions Log volume for each side Add notes about how you're feeling or what's working See weekly trends to spot patterns Quick entry for those rushed moments Set reminders that actually help Different schedules for day and night (because 3am is different) Based on when you actually last pumped Won't spam you when you're already pumping Your data, your way Import from CSV if you've been tracking elsewhere Export everything for your lactation consultant or doctor Everything stays on your phone - no accounts, no cloud nonsense Keep it private No tracking what you do No ads about baby products No account required Good for: Figuring out your pumping routine as a new parent Keeping track when you're back at work Having data ready for doctor visits Seeing if your supply is actually changing or if it just feels that way The real story: I built this because existing apps were either too complicated or missing basic features. When you're pumping every few hours and running on no sleep, you need something that just works. No fancy features you'll never use, no overwhelming interface - just the essentials done well. The app focuses on what actually matters: tracking your sessions, gentle reminders, and seeing patterns over time. That's it.
