A note from the founder

I’m building a calendar
and I know how that sounds.

When I tell someone what I’m building, there’s a pause first, and then some version of the same sentence:

What people say

“A calendar? Calendars are boring. That space is saturated, and nobody wants another one.”

It’s always said kindly. It’s meant as a warning, and it is a fair one.

They’re also right about what is in front of them. Saturated is the right word for the shelf and the wrong one for the problem: there are dozens of calendars and they are all the same calendar, a grid you feed. After twenty years the kindest thing anyone can say about the category is that it works. So of course nobody asks for a better one. You don’t ask for a better version of something you gave up on.

Then I asked the people who’d applied what they actually wanted. I had a clever answer ready, and I wanted to hear them say it back to me.

Nobody said it. One after another, they told me a version of the same sentence:

What they asked for

“Make it fast. Planning one dinner should take seconds, not an evening of messages, and I don’t want to live in the app to do it.”

Nobody said the word calendar there either. They described one. Ask people cold and a calendar is the last thing they want; ask what is actually slow in their week and they describe exactly what a calendar was supposed to do. That gap is the whole reason I’m doing this.

It wasn’t what I’d been building either, and it took me a few days to stop arguing with it, but eventually I put down the fancier thing nobody had asked for and started building what they’d described.

Once I’d heard it a few times, I couldn’t stop seeing the reason for it. Every calendar you’ve ever used was built for work: meetings, invitees, a free half hour on Tuesday, one person managing their own job.

Your life isn’t shaped like that. Dinner with three friends takes a group chat and twenty messages before anything lands in a calendar, and the people you most want to see are somehow the hardest ones to find a time with. The tool that runs your life is the one doing the least for you.

So it’s not that time is a boring subject. It’s that everything ever built for it was built for work, and you were handed the work one for your life.

So Kalendars is a calendar for your life, not your job.

The first one built like it is 2026 and not 2010, and nothing more exotic than that. The first thing you notice is the speed: planning something takes less time than explaining what you wanted. Three things carry it.

Say it, don’t schedule it. “Dinner with Sam on Thursday” is the whole interaction, and most of the time you won’t type even that. The slot is found and the invites are out before the month view would have opened.

Plan with anyone. You add the people who are coming from your contacts, or a whole group at once, and send one link that drops the plan into their own calendar. No app on their side, no account, and no email address you were never going to have.

Your week in one look. Colored by what it is for rather than by which account it came from, so you can see the shape of the week coming without reading a single title.

None of it has to be learned. Every flow goes where your hand was already going, and the speed does the rest: planning stops feeling like admin and starts feeling like saying what you want and having it be true.

So here is what I’m asking.

Kalendars is coming soon to the App Store. What I’m asking for is the thing I actually need and can’t buy: use it for real, on your own life, and tell me the truth about it, including the parts that are bad.

What you get for that is a real say in what I build next. Some of it is already in:

Plan with someone. For a one-on-one, you offer a few of your times and your friend picks the one that suits them.

Ask Kuberdon. Say a plan out loud and let it do the typing.

And this is coming next:

Find a date. The same for a group: one link, and everyone votes on the days that work.

Your calendar is the app you open the most and love the least. Or you stopped opening it, which is the same verdict said more quietly. That is what I’m trying to fix. I want it to be the one you actually like using.

So yes, a calendar. Of all things. Everyone already has one, I still think none of them has been built properly, and I’d rather be wrong about that in public than right about something smaller.
