Tandem Tandem
Early access
A private family operating system for iOS

Your family, in sync.

Tandem reads your calendars, school emails, and delivery notifications, then answers the four questions you actually open your phone for. It is not a shared calendar. It is an assistant that already read everything.

01

What's happening now

02

What's next

03

What I need to do

04

What I should know

The Tandem feed: Right Now, a leave-time alert, and today's events
01 — MORNINGS

Three numbers, never one.

School bell time, on-campus time, and leave-home time are three different facts, so Tandem keeps them apart. Collapsing them into a single number is how families end up late every morning.

LEAVE HOME
20 min drive, traffic included
8:55 AM
ON CAMPUS
15 min before the bell
9:15 AM
BELL
Oakview School
9:30 AM
02 — INPUTS

It reads what nobody put on a calendar.

A coach moves practice in an email and the calendar never hears about it. Tandem catches the change, puts it in your day, and can always tell you where it got that from.

“Heads up — Monday practice moves to 4:30 at the rec center for the rest of the season.”

03 — RESTRAINT

It only asks when it doesn't know.

Pickup is settled every day, so Tandem never brings it up. Drop-off is the part that varies, so that is the one thing it raises: one tap, two names.

A child's day in Tandem: drop-off offering two names, pickup already settled
04 — UP CLOSE

The parts you'd squint at.

Four details, lifted straight out of the screens above at full size.

The Right Now card: Next, Milo pickup at 3:00 PM, with three bullets — leave for Brookfield Prep at 2:36 PM, Rosa is out at 4:00 PM, still to pack basketball shoes.
RIGHT NOW
One card that answers the whole afternoon — the next thing, and the three facts that change what you do about it.
Theo's day: 9:15 AM drop-off offering Alex or Sam, 9:30 AM at Oakview marked Now, 3:15 PM pickup already assigned to Sam, 3:30 PM basketball practice also Sam.
THE DAY, IN ORDER
Drop-off is still open, so it offers two names. Pickup and practice are settled, so it just shows who has it.
Leave-time alert: Leave for Brookfield Prep at 2:36 PM — 20 min drive, traffic building on Millbrook Road plus 6 min, Sam has it.
LEAVE TIME
Not the appointment time. The time you walk out the door, with traffic already counted.
Two event rows: 8:00 AM Milo at Brookfield Prep marked Now, and 8:00 AM Rosa on duty, regular shift, also marked Now.
EVENT ROWS
Colour-coded per person, timestamped, and tagged Now while they're actually happening.

Private by design.

A family's calendars, email, and children are not training data. Tandem never sells family data and never uses it to train a model.
