Luna  /  About
Two people · Two time zones

Made by two people
who sleep too late.

Luna is the work of Mira and Tom — one in Berlin, one in Mexico City, seven hours apart. We’ve been writing software for phones for a combined eighteen years. This is the first thing we’ve built that we wanted to keep on our own phones.

Mira Karjalainen
CO-FOUNDER · IOS, DESIGN
Berlin

Six years on the iOS team at a sleep-tracking company that ended up selling the data she was hired to protect. She left, moved her studio above a Kreuzberg bakery, and started drawing what a phone could look like at 11 p.m. if nobody was watching. Luna is the answer.

Tom Reyes
CO-FOUNDER · ANDROID, INFRASTRUCTURE
Mexico City

Twelve years writing Android — the last four at a hardware company you've heard of, the four before that at a startup you haven't. He builds the parts of Luna that have to keep working when your phone reboots at 3 a.m. and the schedule has to come back on by itself. Reads astronomy textbooks for fun.

Why we’re building this

Both of us have spent our careers shipping software for phones. Both of us, at some point in the last year, realised we were reading our own apps in bed at midnight and squinting like our parents used to squint at restaurant menus.

The first night Mira tried a homemade red overlay on her phone, she fell asleep ninety minutes earlier. The second night, the same thing. The third night she sent Tom a screenshot at 2 a.m. his time saying “I think this is a product.” Tom, who had been writing his own warm-light prototypes on Android for six months, sent back a screenshot of his.

We could have shipped a free version with banner ads. We could have shipped a subscription. We could have shipped both. Instead we did the boring thing: we charged for it, once, the way you’d charge for a flashlight. The point of Luna is that you stop thinking about it. That is hard to do if the app needs you to renew it every month.

We’re building Luna the way we wish more software was built: slowly, by people whose names you can look up, with no dashboard telling us what to do next. We answer our own email. We push our own builds. When you write to us, the reply is from a person who’s been awake too long.

Come along for the build.

One hundred founders get the first copy, a vote on what we build next, and a thank-you in the credits. We’d like you to be one of them.
