The GYST Today screen on iPhone, a week of overdue tasks about to be handled.

Calendar · Tasks · Habits · Lists

From overwhelmed to on top of it.

GYST pulls your calendar, tasks, habits, and lists into one calm place — and uses AI to keep the week ahead handled.

Native iPhone app and full web app. No credit card.

One place for all of it

The stuff of a real life, finally in one view.

Calendar, tasks, habits, and lists don't live in four apps that never talk. In GYST they share one timeline — so nothing falls through the cracks between them.

11 event categories 4 habit types 10 habit tiers 10 themes
GYST week view: a work day, a Hawaii family vacation span, a PTO all-day bar, a Lakers game, and an insight band with weather, markets, and busy hours.

Calendar & timeline

Your real week, at a glance.

Events lay out on a day timeline with the day's weather, markets, and busy hours reading right above them. Trips and vacations stretch across the days they actually span.

  • Recurring events, multi-day spans, and shared family events
  • An insight band with weather, markets, sports, and moon phase on your actual days
  • Month view draws each day's load as a ring of arcs

Tasks

Nothing slips.

Every task carries two dates: when it becomes available, and when it's actually due. GYST hides it until it's yours to do, then nudges you at the edges — and flags anything finished late.

  • Available-from and deadline dates, with priority and recurrence
  • Reminders when a task opens and when a deadline passes
  • Tasks link to events — birthdays even spawn their own reminder
GYST habits dashboard: nine habits with tier-art icons, streak counts from 3 to 90 days, and count, timer, and check-off controls.

Habits & routines

Streaks worth keeping.

Track a habit as a simple check, a count, a timer, or something you're quitting. Every streak climbs ten named tiers, each with its own evolving art — and a missed day can spend a banked cheat day instead of breaking the run.

  • Binary, count, timer, and quit-style habits
  • Reusable checklists and workout routines with per-set tracking
  • On iPhone, habits can auto-complete from your Apple Health rings
A shared birthday wishlist in GYST. A note reads that claims are private — the owner can't see what's claimed, only other members can.

Lists

Shared — and actually private.

Start from a dozen templates: grocery, packing, books, gifts, and more. Share a list with friends for live, item-level collaboration. On a gift wishlist, members can claim items — and the owner never sees who claimed what.

  • A grocery master list that reorders itself to your store
  • Owner-blind claims on gift wishlists

It's alive

The app rewards you for living your life.

Both of these are the real product, running right here on the page — not a video. Try them.

Habit tiers · live

Watch a streak level up.

This is the exact effects engine from the app. Each tap advances the streak a tier — the art evolves and its particles ignite.
