Social media blocker for Android
How much of your life does the feed get?
Tap your hours on social media a day. Be honest: your phone's screen time already knows.
Your 16 waking hours. The bright part is what the feed takes.
What those days turn into
Fewer feeds leaves room for the four things scrolling quietly takes from you.

Deep work
Hours of real focus on the work that moves your life forward.

A clearer mind
Less noise, better memory, ideas that have room to grow.

A healthier body
The walk, the gym, the early night you kept postponing.

A fuller life
Full attention for family and friends, not half of it.

Why willpower fails
Motivation fades by Tuesday. A system doesn't.
Feeds are built by thousands of engineers to keep you scrolling. Fighting that with willpower every hour is a losing game.
The people who seem to have the most self-control mostly avoid temptation in the first place. They change their surroundings, so there is nothing to resist. Umer OS is that change, built into your phone.
Great work came from undistracted minds
Long stretches of quiet thinking are behind some of the biggest ideas in history.

Isaac Newton
Sent home by the plague in 1665–66, he worked alone and laid the groundwork for calculus, optics and gravity.

Charles Darwin
Kept a strict daily routine of quiet work and long thinking walks while writing On the Origin of Species.

J.K. Rowling
Checked into a hotel room to escape distractions and finish the last Harry Potter book.

Albert Einstein
A quiet patent-office job left room to think. In 1905 he published four papers that changed physics.

Marie Curie
Years of focused work in a cold shed lab. The first person to win two Nobel Prizes.

Maya Angelou
Rented a plain hotel room with nothing on the walls, just to write without distraction.

Carl Jung
Built a stone tower by a lake, without electricity, to think and write in peace.

Beethoven
Took long daily walks with a notebook. Many of his ideas began there.
Cal Newport
Computer science professor who wrote the book Deep Work. He has never had social media.
You don't need a plague or a hotel room. You need a phone that stops pulling at you. Umer OS gets you there.

The science, in plain words
Just having your phone on the desk, even face down and silent, lowered people's brainpower in tests. In another room, they did better.
Ward et al., 2017 · ~800 peoplePeople paid to quit Facebook for 4 weeks gained about an hour a day and felt happier.
Allcott et al., 2020 · 2,743 peopleWhen people were interrupted, they rushed to catch up, and felt more stress, frustration and time pressure.
