The short version
Clue logs what your cycle is doing. Lunar uses your cycle to change what your task list shows you. If you just need to predict your period, Clue is excellent. If you have ADHD and your luteal week wrecks your focus, you need something that connects the cycle data to your day.
What Clue does well
- Clean, accurate period tracking. Predictions get better with each cycle logged.
- No pink-ribbon aesthetic. Calm, evidence-based design that doesn't infantilise.
- Privacy-forward. Doesn't monetise your most sensitive data the way some trackers do.
- Mood, symptom, and pain tracking. Decent log of what your body is doing each day.
Where Clue stops for ADHD women
- No task management. Clue is a tracker, not a planner. The data sits in a chart.
- No energy or focus filter. You can log brain fog as a symptom, but nothing in the app uses it to change what you do next.
- Doesn't help on the actual luteal day. Predicting your period doesn't help you decide which of 12 tasks to attempt this morning.

Why Lunar exists
For years women have tracked their cycle and then… done nothing with the data. The chart sits in one app. The to-do list sits in another. Nothing connects them. Lunar's whole thesis is that the cycle data should change what your task list shows you every morning — automatically.
On a luteal-phase exhausted day, you see 2-3 tasks that fit. On a follicular high-energy morning, you see the heavier work. The cycle isn't decorative; it's the filter.
What knowing your phase actually gives you
Clue tells you "you're in your luteal phase." That's useful information. But for women with ADHD, the useful action is: now what do I actually do differently today? Clue stops at the insight. Lunar starts there.
When you check in as "luteal + exhausted" in Lunar, your task list responds. The high-energy tasks disappear from view. The big creative work gets deferred. What surfaces are the small, low-friction things — the admin task that takes 10 minutes, the reply that needs one sentence, the break that's actually on your list as a priority. The phase data becomes a daily planning input, not just a chart.
What a real week looks like
With Clue only. You open Clue on day 22. "Late luteal: you may experience mood changes, bloating, lower energy." You nod, close the app, open your task list (in Todoist, Notion, or wherever), see 18 items, don't know where to start, try one thing, get stuck, feel like you're broken, spiral. The insight didn't help because nothing connected it to action.
With Lunar. Same day. You open Lunar, check in: luteal, energy level exhausted. The list collapses to 2 tasks. You do both. You close the app. That's it. The phase awareness wasn't decorative — it changed what you saw.
Common questions
Should I use Clue and Lunar at the same time?
If you rely on Clue's detailed symptom logging, fertility tracking, or partner sharing features, keep it. Lunar's built-in cycle tracking is lighter — it captures phase and energy, not the full symptom battery. You can run both with minimal effort: track deeply in Clue, plan daily in Lunar. Or consolidate to Lunar if you just need the basics.
How accurate does my cycle tracking need to be in Lunar?
Not very. Lunar doesn't require you to connect a precise cycle history. You select your current phase at check-in — "I think I'm in luteal right now" is enough. If you're unsure, you can use the energy level filter alone and skip the cycle phase entirely. The app adapts to honest estimates, not precise data.
Does Lunar work for PMDD?
Yes — many Lunar users have PMDD. The luteal phase filter is specifically useful during PMDD windows, where the app reduces your visible task list automatically during your most symptomatic days. Several users have described Lunar as the first tool that gave them "permission to have less on your plate during PMDD" without requiring them to manually reschedule everything.
If you came from Clue
You can keep Clue for deeper symptom logging and use Lunar for daily planning — they're not competing. Or simplify to Lunar alone if you don't need the full tracking depth. Either way, the breakthrough is the step from "I see I'm in luteal" to "and here are the 3 things that actually fit today, automatically." That connection is what Clue alone doesn't make.
