WHY IENON

Most crossed wires start
with things kept in different places.

Plans live in a calendar app, the shopping list is buried in a chat thread, and chores get sorted out loud in passing — the more scattered things are, the more often "I thought I told you" happens. ienon gives everything about home a single place to live.

FEATURES

What you can do with ienon

Three core features you will open every day, plus the tools that keep the household running. All inside the same app.

Calendar

Plans and chore turns,
on one shared calendar.

Work meetings, school events, whose turn it is to take out the trash — everyone's day is visible at a glance. "What's on today again?" is answered just by opening the app.

Shopping list & pantry

Let the list carry
"grab this on your way home".

Edit what to buy and what's already in the cupboard together, in real time. Open it on the way home and nothing gets forgotten or bought twice. The moment you tick something off, the other person sees it.

Meals & recipes

"What should we cook tonight?"
Decide it together.

Search recipes by what's in the fridge or by what you feel like eating. Plan a whole week of meals at once and send the missing ingredients straight to the shopping list.

A DAY WITH IENON

A day with ienon

One Friday with the Asahi family: two adults and a one-year-old.

7 AM
Morning
"What does daycare need today?"
Calendar
A quick check of the notes on the calendar event. The same plan is on both phones, so there's nothing to ask.
12 PM
Lunch break
"I'd love to go somewhere this weekend."
Notes
Jot a few places into a note. Before heading home, your partner reads it and comments "let's go here!"
6:30 PM
On the way home
"Milk, bread, and diapers."
Shopping list
Open the shopping list and tick things off. Whoever is home keeps the pantry updated, so nothing gets bought twice.
7:30 PM
Dinner
"What can we make with what's in the fridge?"
Meals
A quick recipe search settles it. Missing ingredients go straight onto the shopping list.
10 PM
Night
"Thanks for today."
Mood stamps
At the end of the day you send each other a mood stamp. An ordinary evening gets a little warmer.

With the virtual member feature, all three kids' schedules finally fit on one screen. "I completely forgot!" happens far less often, and we now run the family calendar almost entirely in ienon.

★★★★★
This is exactly the app we'd been wanting. It's not just shared plans — we track how we're feeling in the same place. The "I told you" / "you never said that" moments have dropped a lot.

★★★★★
We tried a lot of shared calendars and finally settled on ienon. We no longer have to text back and forth about picking things up on the way home, and a small daily stress just disappeared.
