What an energy-based planner does
An energy-based planner starts from how much energy you have today, not from the clock. Instead of asking when you will do a task, it asks what you can do with the energy you have, and shows you tasks that fit.
That matters most when your capacity swings from day to day, as it often does with ADHD. The apps below take different routes to the same idea: some filter or hide tasks, some use wearable data, and some build the day around a daily check-in.
Lunar
Lunar is an iPhone planner for women with ADHD that plans tasks around cycle phase and energy. You check in with your energy (exhausted, low, okay or high) and, if you choose, your cycle phase, and your list shows the tasks that fit. You can also add tasks by voice brain-dump.
Best for: women with ADHD whose focus changes across the month and who use an iPhone. Price: free to download, 14-day free trial, then $79.99/yr (App Store listing, October 2026).
Lifestack
Lifestack ("Lifestack: AI Planner for ADHD", by DeMind Inc.) is an AI planner for ADHD that describes "Energy Zones" and connects to wearables and calendars. According to lifestack.ai it runs on iPhone, Mac, Android and Chrome.
Best for: people who want a cross-platform ADHD planner with wearable and calendar integrations. Price: lifestack.ai lists $9.99/mo, $49.99/yr (with a 7-day trial) and a $120 lifetime option (as listed on lifestack.ai, Oct 2026).
Unrush
Unrush ("Unrush: Pace Yourself", by Gejun Zhu) starts with a daily capacity check-in (Full, Half or Survival) that hides heavy tasks on low days. It also uses effort levels and anchor tasks, and it runs on iPhone (iOS 17.6 or later per the App Store listing).
Best for: people who want a simple capacity check-in without cycle tracking. Price: free to start, with a paid Unrush+ tier and a 7-day trial; see unrush.app for current pricing.
ZoBud
ZoBud is a daily planner that asks you to log your energy and mood in quick check-ins, then sizes each task by the effort it takes and matches it to your higher- or lower-energy times of day. It runs on iPhone, Android and the web, and has a free tier.
Best for: people who want time-of-day energy planning on more than one device. Price: free tier available; see zobud.com for paid plans.
Rhevio
Rhevio is an iPhone task planner for adults with ADHD. It picks one task and shows only that, can suggest your energy level from sleep data if you allow Apple Health, and carries unfinished tasks over without streaks to break. It needs iOS 26 or later.
Best for: people who want the app to choose one task for them. Price: free trial, then a subscription; see Rhevio on the App Store.
Phoebe
Phoebe schedules tasks around a repeating energy cycle that you set, anywhere from 1 to 99 days. Many people use it with their menstrual cycle; it also works for shift schedules or other rhythms. You set effort points for each day, so high-energy days take more.
Best for: people who want tasks spread across a cycle, rather than filtered day by day. Price: free during early access, according to getphoebeapp.com.

How Lunar plans around energy
Lunar gives every task an energy level and shows only the tasks that fit how you feel today. Tasks that don't fit go quiet, not away, and nothing is marked late. Read the full explanation in energy-based planning in Lunar.
Your cycle phase is optional context on top of energy. See how that works in the cycle-aware ADHD planner guide, or browse the ADHD planner for women overview.

Common questions
What is an energy-based planner?
An energy-based planner helps you choose tasks by how much energy you have right now, not by the clock. You check in with your energy level and the app surfaces tasks that fit, instead of asking you to schedule everything into time slots.
Which energy planner works with my cycle?
Lunar plans tasks around both your daily energy and your menstrual cycle phase (period, follicular, ovulation or luteal). Sharing your phase at check-in is optional.
Is Lunar free?
Lunar is free to download, with a 14-day free trial, then $79.99/yr.
Does Lunar work on Android?
No. Lunar is on iPhone, iOS 26.1 or later.
Which app plans tasks around my energy level without a wearable?
Lunar does it with two taps: you pick today's energy (exhausted, low, okay or high) and your cycle phase, and it shows only the tasks that fit. ZoBud also uses daily check-ins, Rhevio picks one task for you, and Lifestack reads wearable data instead.
