The short version
Muna is a cycle-tracking and planning app with Grace Mode, brain dump, calendar integration and Muna Chat. Lunar is a task list that hides the tasks you can't realistically start today, based on your energy and cycle phase.
What Muna does well
- Cycle tracking with planning support. Muna plans around your cycle, with daily to-dos, energy forecasts and wellness prompts.
- Check-ins. A daily check-in to tell the app how you feel.
- Calendar sync. Muna syncs Google, Apple and Outlook calendars.
- Grace Mode, brain dump and Muna Chat. Extra tools for harder days and messy thoughts.
- Premium trial. Muna Premium is $9.99 a month with a 30-day free trial.
Where Lunar is different
- Your whole list, filtered. You keep every task. Lunar shows the ones that fit your energy (exhausted, low, okay or high) and, if you choose, your cycle phase.
- Nothing piles up. Tasks that don't fit go quiet. They aren't deleted and they don't turn into an overdue pile.
- AI task breakdown. A stuck task becomes small steps you can actually start.
- No streak shaming. A quiet week is data about your body, not a failure.
- Irregular cycles are fine. Lunar doesn't predict your cycle. You pick your phase at check-in, or skip it.
