What each one does.
| What | TimeLoop | Lifestack |
|---|---|---|
| In one line | You say or type what must happen; it plans the day and replans it | A smart daily planner built around your energy, in its own words; its App Store listing calls it an AI planner for ADHD |
| From words to a plan | A sentence, typed or dictated; a scheduler places things around your fixed events (Pro) | “Chat with Lifestack”, a copilot for daily decisions; its App Store listing says you can ask the AI to plan your day, week or routines |
| How the day is sized | One question a day; a low day is offered lighter, with before and after. The answer stays on your phone; free | From your sleep, recovery and focus, in its own words: it drafts a schedule that puts the right work at the right time, and “Energy Zones” align important work with your peak energy |
| Where that comes from | From you: “How are you feeling?”, three faces, one answer a day. TimeLoop measures nothing itself; with Pro it may suggest the answer from what your watch or ring already put on your phone, worked out there | From the iPhone’s health store and from devices such as Oura, WHOOP, Garmin, Apple Watch and Fitbit, by its App Store listing; that data is shown beside your calendar and plans |
| Meals and rest | Lunch and dinner are placed around the times you eat, inside your waking hours; a lighter day never moves a meal | “Meals and Sleep”: each morning the AI has mapped your meals and rest around the day’s demands |
| When the day slips | Running late: the rest of today is planned again, with before and after, and undo | Its chat is “always in context, always adaptive”, in its own words; the pages we read say nothing more specific about a late day |
| Calendars | Reads the calendars on your phone and Google Calendar as fixed events, writes your plan into its own “TimeLoop” calendar, and answers Google Calendar invitations; free | Google Calendar and Outlook, by its App Store listing; its pricing page gives every plan “unlimited calendars and tasks” |
| Tasks from other apps | On iPhone, Reminders come in and get a time, and “done” goes back; free | Todoist and Trello “and more”, by its App Store listing |
| Travel time | Measured from where you are, with a time to leave (Pro) | Nothing about it on the pages we read |
| With other people | Circles joined by a link, a shared list in each, finding a time everyone is free; with Pro, telling them when you run late | Nothing about it on the pages we read; its pricing page offers a “group deal” on request |
| Where it runs | iPhone and Android phones (coming soon to both stores) | iPhone, Mac, Android and Chrome, in its own words, with a web app you sign in to; an Apple Watch app on its App Store listing |
| App languages | English and Slovenian | English, on its App Store listing |
| Free and paid | A free version; Pro monthly or yearly. On the App Store the yearly plan starts with a free week | A subscription, monthly or yearly, or a lifetime plan paid once; a 7-day free trial on the yearly plan. Its pricing page lists no free plan, and its site says “Try free now” |
As of October 2026. What is said about Lifestack comes from its own website and store listing; if it has changed since, their pages are right. Lifestack belongs to its makers and has nothing to do with TimeLoop.
TimeLoop fits if
Your days are shaped by appointments in other places and by other people, you want the way there counted in and the plan moved when you run late, and one question a day is as much as you want asked about how you feel.
Lifestack fits if
You wear a watch or a ring and want the day built around what it knows of your sleep, recovery and focus, with meals and rest planned in, on a Mac and in Chrome as well as on your phone.
Your day.
Planned for you.
You say what has to happen. TimeLoop keeps the fixed things where they are and finds a time for the rest.
On Today
Asked once a day
How are you feeling?
Answered, on a full day
Opened
A lighter day
Gym moves to tomorrow, 17:30.
Study stays: no other day has room.
What TimeLoop adds.
Planned around what cannot move
TimeLoop reads your calendar, treats what is in it as fixed and fits the rest into the room that is left.
A late day, planned again
Tap how late you are and see the rest of the day before and after, with undo.
The way there, and the weather
With Pro: when to leave from where you are, and the forecast at the place, on every event that has one.
The difference that matters most
Lifestack starts from your body. In its own words, it takes your sleep, recovery and focus from a watch or ring and drafts a schedule that puts the right work at the right time, with meals and rest mapped in each morning. TimeLoop starts from your calendar. It asks one question a day, how you feel, and when today holds more than your answer carries, it offers a lighter day: before and after, with undo. TimeLoop measures nothing itself.
If what you want is a planner that follows your body through the day, Lifestack is built for that, and it is on more devices: Mac and Chrome as well as the phone. TimeLoop has nothing like its energy zones. What TimeLoop does instead is fit the day around what cannot move: the meetings, the trips and the people in it.
Asked before you asked.
Does TimeLoop track my energy?
No. It asks how you feel once a day, with three faces, and sizes the day by your answer. It keeps no mood journal. With Pro it may suggest the answer from what your watch or ring already put on your phone, and you still choose.
Do I need a watch or a ring for either?
Not for TimeLoop: the question is answered by you, and a lighter day is offered from that. Lifestack’s App Store listing names the iPhone’s health store and devices such as Oura, WHOOP, Garmin, Apple Watch and Fitbit; whether one is needed is a question its own FAQ answers, on its support pages.
Does TimeLoop run on a Mac or in Chrome?
TimeLoop is for iPhone and Android phones, and also runs in a browser; its Mac app is not out yet. Lifestack says it is available on iPhone, Mac, Android and Chrome.
Where do the facts about Lifestack come from?
From Lifestack’s own website and App Store listing, read in October 2026. If something has changed since, their pages are right and this one is out of date.
Some days you have less in you than the plan assumes. TimeLoop asks how you feel, once a day, and when today holds more than that, it offers to move the heaviest things that can wait.
