Follow your current fast and organize a week that fits your routine. Start or end your timer, adjust times and review your history. Rest days belong in your schedule: the plan should fit your life, not the other way around. The core timer is free. Custom Week is available as a one-time purchase, without a subscription. People who used FastZen before version 1.1.0 keep that access without paying. This is a tracking tool, not medical advice or a weight-loss promise.

PumpPal is a breast pump tracker for moms who want more than a stopwatch. Track pump sessions, log milk output, manage your freezer stash, and see how your supply is trending over time. PumpIQ uses the information you enter to estimate stash coverage, goal progress, and a possible last-pump date so you can plan with more confidence. Use PumpPal on your paired Apple Watch to start and end a pump, then add the amount on iPhone. Home Screen widgets let you see your timer and start a pump with a tap. Features: - Start or log pumping sessions in seconds - Track output, duration, sides, and session history - Manage freezer stash bags and know what to use next - See daily totals, averages, and goal progress - Use PumpIQ for trends, projections, and stop-pumping forecasts - Export your data when you need it PumpPal is designed for late nights, busy days, and every ounce in between. Your data stays on your device. PumpPal does not provide medical advice. For health or feeding concerns, consult your pediatrician or lactation consultant.

Verdict
The clearest difference is update cadence: PumpPal at daily against FastZen's weekly. PumpPal also leads on monetization model (free vs free with in-app purchases). On price, review sentiment, ads and in-app purchases there is nothing between them.
