Convenient by design

Five things that only happen
when everything's in one app.

Each workflow shows how multiple modules collaborate without any setup — one shared calendar, one shared budget, one shared notification center.

Workflow 01Travel+Budget+Tasks+Notes

Plan a trip end-to-end without a spreadsheet.

Create the trip once and every linked module reacts. The calendar gets your dates, link a trip bucket in budgets to keep spending in check, the packing list lives with the itinerary, your photos and notes attach to the trip — not to a folder you'll never find again.

1
Build the day-by-day itinerary Travel
Drag bookings, flights, and accommodation onto each day. Offline-cached for the plane.
2
Create a dedicated budget bucket for your trip Budget
Every receipt logged on the trip routes back to it. You see "Hobart: $1,840 / $2,500" on your dashboard.
3
Packing list lives on the trip Tasks
Reusable templates — "Cold weather", "Beach", "Work conference" — tick off as you pack.
4
Tag your note entries Notes
Search "Hobart" later and find the itinerary, the budget, the notes, the photos — in one timeline.

Workflow 02Events+Directory+Budget+Tasks

Throw a wedding — or a backyard birthday — without losing the thread.

Events is the heaviest module in CHAIOS for a reason: occasions touch everything. Guests, vendors, run sheets, budgets, RSVPs and reminders — all of them stay tied to the one event card. Reuse the whole thing as a template next year.

1
Build the run sheet & guest list Events
Timeline blocks, RSVPs, dietary needs, table plans — one source of truth your co-host can edit too.
2
Book vendors from the Directory Directory
Verified local florists, caterers, photographers. Enquiries land in your event inbox, not a generic email.
3
Every quote attached as a line item Budget
Vendor budgets roll into the event total. Hit your cap? CHAIOS tells you before you commit, not after.
4
Reminders fire on the right day Tasks
"Final headcount due" lands in your unified notifications — not a calendar nudge in a different app.

Workflow 03Baby+Health+Household+Notes

Welcome a baby and keep both parents in sync from day one.

Baby tracking gets a bad rap because most apps live in a silo: one parent logs the feed, the other has no idea. In CHAIOS the log is on the family dashboard, the growth charts roll into the GP visit, and the chore split sees the 3am wake-ups.

1
Both caregivers log in real time Baby
Feeds, naps, nappy changes — one shared timeline. No more "did you feed her at 4?" texts.
2
Growth + milestones roll into Health Health
Export a clean PDF for the paediatrician straight from the app. No screenshotting different screens.
3
Household chores rebalance Household
CHAIOS sees who's on baby duty tonight and shifts the dish roster automatically. Reset weekly.
4
A journal you'll actually keep Notes
A few lines a day, document your baby's milestones.

Workflow 04Household+Budget+Tasks+Vault

Run a household where nothing falls through — even the boring stuff.

Quarterly insurance, the smoke alarm battery, the rates notice, the rego renewal — the bills that quietly cost you when they slip. CHAIOS handles the recurring chore + spend + reminder + receipt as one item, not four apps.

1
Recurring household tasks Household
Quarterly, monthly, weekly — with rotation. "Who's on bins this fortnight" answers itself.
2
Each bill auto-creates a budget line Budget
Annual rates of $2,400? CHAIOS reserves $200 / month. You see the smoothed-out reality, not the quarterly shock.
3
Meal plans become shopping lists Tasks
Drag a recipe onto Tuesday — ingredients merge into the weekly shop, sorted by aisle.
4
Policy numbers + warranties in Vault Vault
Insurance policy attached to the chore that renews it — one tap from claim to policy number.

Workflow 05Habits+Health+Tasks+Rank

Build a daily routine that actually compounds.

Habits without context die. CHAIOS pulls your morning run into the calendar, your check-in into the agenda, your streak into your rank — so a 6am run on Tuesday isn't an isolated tap, it's a step in a story that earns points.

1
Streaks with flexible schedules Habits
Daily, weekly, custom ("3× / week"). Sick day? Pause without killing the streak.
2
Logged metrics chart together Health
Running streak + resting heart rate + sleep on one chart. See the loop, not isolated numbers.
3
Today's habits sit in the agenda Tasks
Not a separate Habits screen to remember — they're alongside your 09:30 meeting and your dinner plan.
4
Streaks earn points, points climb ranks Rank
7-day streak = +50 pts. Hit Strategist and unlock the "Disciplined" permanent achievement.

One of each, not a dozen

The four surfaces every module quietly feeds into.

This is what makes CHAIOS one app, not a dozen. The calendar, the budget, the search, the inbox — all unified, all populated automatically by whatever module you're working in.

One calendar. Every module.

Events, due dates, travel, household chores, baby appointments, habit check-ins, savings milestones — all rendered on the same week view. Filter by colour. Share by household.
