My Story
A few years ago, I caught myself doing something I didn't mean to do.
I'd unlocked my phone to check the time. Forty minutes later, I was inside a feed I hadn't planned to open, on an app I hadn't planned to use. I put the phone down feeling vaguely tired and a little lied to. By the phone, but mostly by myself.
Most apps are designed to capture attention and hold it. A device that's supposed to be a tool but keeps quietly taking the lead.
I'm Rolet. I've been building Yin Yang for the last two years.
What I tried before I built anything
The first thing I considered was a dumb phone. The appeal was obvious: no feeds, no apps, no problem. But a dumb phone on its own wouldn't cover the things modern life quietly assumes a smartphone can do, like scanning a code at the counter, navigating when you're lost, or capturing something worth keeping. I'd end up carrying two phones. And spending hundreds of dollars on a second phone just to get away from the apps on the first one didn't make sense.
So I went looking for a software answer instead, and there were a lot of minimalist launchers to try. Some worked for other people but didn't fit how I actually use my phone. They left out things I depended on, or held the line so tight I just stopped opening them. None of them landed in the middle ground I was looking for.
I couldn't find one, so I started building one.
The first version didn't work
I started in March 2024 with no real roadmap. About six months of solo work later, I shipped the first version of Yin Yang on Google Play in September 2024.
It didn't click. People installed it, looked around, and left. The shape of the idea was right but the execution was off. I'd built what I thought a minimalist launcher should be, not what someone reaching for one actually needed.
So I redesigned the whole app from scratch. Three months, full rebuild. The second version started getting traction. Small, but real. People stayed, sent feedback, told friends.
That was the turn. The year and a half since has been steady iteration. A lot of what's in Yin Yang today started as one sentence in someone's email or review.
The idea I kept coming back to
What kept coming back was that noticing the pattern is half the work. Restriction made me resentful. Awareness changed things.
That's what Yin Yang is built around. The launcher shows you what's happening, you decide what to do about it.
I landed on three screens: a quiet home, one swipe left for awareness, one swipe right for the things I actually need.
Why "Yin Yang"
The name is the philosophy. Not rejecting technology, not surrendering to it. Finding the balance between what your phone can do and what you actually want it to do for you. Useful and quiet. Capable and calm.
Where it is today
A year and seven months on the Play Store. Around 50,000 people use it across 10+ languages, with 4.5 stars from 1,210+ reviews. Still just me building it.
I read the feedback that comes in. The app you're using today is mostly the result of people who wrote to me with one sentence about what was missing or wrong. If you have your own, send it.
