FlowSavvy vs Lifestack

FlowSavvy

• Individuals who want tasks placed on the calendar without manual time blocking
• Deadline-driven workloads that shift often during the week
• People who already keep events in Google, Outlook.com or iCloud calendars

Lifestack

• People who want demanding work scheduled when their focus is highest
• Wearable owners who want sleep and recovery data next to their calendar
• People with ADHD who want structured routines and clear time blocks

FlowSavvy

• Basic schedules only 2 weeks ahead and is limited to 3 repeating auto-scheduled tasks, 5 task lists and 1 set of scheduling hours.
• Priority levels, task dependencies, syncing tasks out to other calendars, and the API, MCP and Zapier integrations all require Pro.
• There is no native desktop app. On a computer it runs in the browser or as an installed progressive web app.
• The vendor aims it at individuals and does not offer team or enterprise features.

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.

FlowSavvy

Auto-scheduling

Places tasks into open time on the calendar based on due dates and durations, and can split a task around events. Basic plans 2 weeks ahead and Pro 8 weeks.

Automatic rescheduling

The schedule is rebuilt whenever an event or task changes, and a Recalculate button puts missed tasks back on the calendar. Reschedules are unlimited on both plans.

Scheduling hours

Sets of hours such as work or personal define when tasks may be scheduled. Basic includes one set; Pro allows unlimited profiles.

Calendar sync

Two-way sync with Google Calendar, Outlook.com and iCloud on both plans. Writing FlowSavvy tasks back to those calendars is a Pro feature.

Priorities and dependencies

Pro adds priority levels and dependency chains for tasks that must follow an order. On the free plan, tasks are prioritized by due date.

Task app sync, API and MCP

Syncs tasks with Todoist, Google Tasks, Microsoft To Do and Apple Reminders. A public API, an MCP server for ChatGPT and Claude, and Zapier are Pro-only.

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.
