The core difference
Motion is an AI calendar that automatically schedules your tasks into open time slots based on deadlines, priority, and meetings. It treats scheduling as the problem: give it your task list and calendar, and it figures out when to do everything.
Lunar treats task selection as the problem. Women with ADHD often know their schedule. What breaks down is knowing which tasks they actually have capacity for today — especially when their luteal phase has wiped out their focus and a full task list feels paralyzing. Motion fills your calendar. Lunar shrinks the list to what fits you right now.
Motion also costs $34/month. Lunar's Pro is $10/month, with a free tier.

Who should use Motion
- You have many meetings plus tasks and need them auto-fitted into a calendar
- Deadlines drive your work and you need AI to prioritise around them
- You can commit to a machine-generated schedule and follow it
- You need cross-platform (Android, web, Mac) access
Who should use Lunar
- Your energy availability is unpredictable — especially week to week with your cycle
- Seeing your full task list at once creates overwhelm and shutdown
- You need to know what you can do today, not just what's scheduled
- You want body doubling and AI task breakdown in the same app
- $34/month is too much for a scheduler
The capacity problem Motion doesn't solve
Motion is built on a reasonable assumption: if you know when to do something, you'll do it. For many people, that's true. For women with ADHD whose dopamine drops during the luteal phase, it's not. You can have a perfectly scheduled calendar and still be unable to start the first item on it because your brain doesn't have the resources today.
Lunar doesn't schedule your time. It reads your energy each morning and shows you only the tasks you have capacity for right now — low-energy tasks when you're depleted, high-focus tasks when you're in your follicular peak. It works with your cycle instead of against it.
Verdict
Choose Motion if you have deadline-driven work, many meetings to work around, and the ability to follow an AI-generated schedule — and if the $34/month price makes sense for your workload. Choose Lunar if your primary challenge is that your capacity fluctuates and you need a planner that knows when you're in a low week. At $34/month vs. free, the decision is often made for you.
