The short version
Structured organises your day on a timeline. Lunar organises it by what your brain can do right now. If your capacity is roughly the same each day, Structured is wonderful. If it isn't, the timeline becomes another thing to feel bad about when the day doesn't go to plan.
What Structured does well
- Gorgeous timeline UI. Tasks become time-blocks on a clean vertical day view.
- Subtasks, repeats, notifications. All the basics, done well.
- Calendar integration. Pulls in events so the day view is complete.
- Popular with ADHD users. Time-blindness benefits from a visual day.
Where Structured stops
- Plans assume capacity. "Email Sarah at 2pm" assumes you have an emailing-Sarah brain at 2pm. ADHD luteal-phase says hi.
- No cycle awareness. The Monday in your follicular week is identical to the Monday in your period week.
- Time-based, not energy-based. A 30-minute block doesn't help when you don't have 30 minutes of focus in you.
- Carryover guilt. Unfinished blocks pile up. Each one is a small reminder of failing your own plan.

Why Lunar exists
Time-blocking is a strategy for people whose limiting resource is time. For ADHD women, the limiting resource is often focus capacity — and capacity moves with hormones, sleep, and the week of your cycle. You can have 8 free hours and still not be able to do the 1-hour task.
Lunar inverts the question. Instead of "when will I do this", it asks "can I do this today, given how I actually feel right now". Two inputs: cycle phase + current energy. Then it filters your list to only what fits.
The capacity vs. time problem
Time-blocking assumes your limiting constraint is time. But for women with ADHD on a cycle, the limiting constraint is often executive function capacity. You can have a perfectly blocked 8-hour day and still not be able to initiate the first task. The block exists. The capacity doesn't.
During the luteal phase, when estrogen falls and dopamine dips, task initiation becomes significantly harder. Not impossible — but harder. A rigid timeline doesn't adapt to that. Lunar does: it asks you how much you have today, and then shows you only what fits. On a depleted luteal day, your "time-block" might be 2 tasks. On a follicular high day, it might be 8.
What a real week looks like
Week 2, follicular phase. You open Structured, your day is well-planned, and you actually execute it. Three deep-work blocks, a couple of quick tasks, done. Structured is working well. You might also open Lunar to choose which flexible tasks go in those blocks — both tools complementary.
Week 4, late luteal. You look at Structured. Meeting at 11, blocked time for "project work" at 2, admin at 4. The 2pm block arrives. You stare at the screen. The project is complex, your brain is static, and you skip it. You push it to tomorrow. Tomorrow is the same. By end of week, you have 6 tasks marked incomplete and a gnawing sense that you've failed your own plan.
Same week with Lunar: you check in as "low energy," your list shows 3 tasks that fit that energy level, and you complete 2. No incomplete blocks. No timeline guilt.
Common questions
Can I use Structured and Lunar together?
Yes — many ADHD women do. Use Structured to block fixed commitments (meetings, calls) and Lunar to decide which flexible tasks belong in the open slots. Structured tells you "I have 90 minutes at 2pm"; Lunar tells you what your brain can realistically do in those 90 minutes today.
Does Lunar have calendar integration?
Not yet — calendar sync is on the roadmap. Currently Lunar focuses on task capacity filtering, not event scheduling. For fixed-time events, Structured or your native calendar works better. Lunar shines for the unscheduled task list: what to actually do with the time you have.
Does Lunar help with time-blindness like Structured does?
Differently. Structured's visual timeline directly helps you see time passing. Lunar's approach is task-duration tagging — each task has an estimated time, and the energy filter ensures you're only shown tasks you have capacity for. It won't track the clock for you, but it stops you from picking a 2-hour task on a 20-minute brain day.
If you came from Structured
You can keep using Structured for fixed-time events (meetings, calls, appointments) and use Lunar to decide which of your flexible tasks belong in today's blocks. Most ADHD women who've tried both find Structured great for the calendar layer and Lunar essential for the task selection layer — deciding what actually goes on the timeline given how you feel that day.
