Worth knowing

  • The store also lists two "Unlimited Access" purchases at $8.99 and $49.99 without saying what term or features they cover.
  • The App Store listing notes that the app contains advertising.

Lifestack

  • There is no free plan. Once the 7-day trial on the annual plan ends, a paid subscription is required.
  • Only the annual plan includes a trial. The monthly and lifetime plans are charged without one.
  • The Chrome extension supports only certain Google Calendar and Outlook Calendar views, such as day and week.
  • No Windows app is listed. Lifestack is offered for iPhone, Mac, Android, Chrome and the web.

Key features

Day Flow

Voice planning
Say what you need to do and the assistant builds a schedule for the day or the week from it, without typing each task.
Spoken changes
Plans can be changed by request in everyday phrasing, such as moving a dinner to next Friday, adding 10 minutes to a morning run or shifting several tasks to the weekend.
Calendar and Reminders import
Apple Calendar, Google Calendar and Apple Reminders can be imported so events and to-dos sit in one view. The 1.7.0 release notes describe Google Calendar as import-only.
Timing suggestions
The assistant proposes when to fit in things like a workout or a break, and release notes say it reads free time in the day when placing tasks.
Recurring tasks and categories
Tasks can repeat, carry reminders and be grouped into categories. To-dos without a set time can be reordered by dragging.
Widgets
The App Store version history mentions widgets, which returned in version 1.7.5 and received a further fix in version 1.9.0.

Lifestack

Energy Zones
Predicts high and low energy periods through the day from sleep and health data, so demanding work can be lined up with the peaks.
Plan My Day
Schedules the day's to-dos, routines, meals and rest onto the calendar in one step, turning a task list into time blocks.
Chat with Lifestack
An AI assistant you can ask to build a plan for the day or week or to set up routines. The vendor describes it as a round-the-clock copilot for daily decisions.
Wearable and health data
Connects to Apple Health and wearables including Oura, WHOOP, Garmin, Apple Watch and Fitbit. Without one, it can use an iPhone sleep schedule, Google Fit or Samsung Health.
Calendar and task integrations
Brings several calendars into one view and integrates with Google Calendar, Outlook, Todoist and Trello. Calendar events are labelled by type automatically.
Chrome extension and Apple Watch
The Chrome extension overlays energy levels on Google Calendar and Outlook Calendar, and the Apple Watch app shows energy, calendar and to-dos.
