FIND
Search apps, shortcuts, notes, settings, and arithmetic before your thumb changes its mind.
ANDROID 8.0+ · VERSION 1.0
A quiet home.
A clearer day.
Kern is a minimalist launcher for Android. Find any app in two letters, see your screen time honestly, and pause before the apps you fall into.

KERN / ON YOUR PHONE
Less noise.
More intention.
The actual launcher. A quiet home, fast search, and a little space between you and the next distraction.

SCROLL TO EXPLORE
01 / THE ARGUMENT
Less is useful. Fast is better.
A launcher should remove friction, not only icons.
MINIMALISM IS NOT THE PRODUCT
Removing everything leaves you with less. Kern gives the empty space a job.
NOTICE
See the day as time and interruptions. No score. No sermon. Just the record.
CAPTURE
Keep a page, a task, or a thought one swipe away from wherever you are.

02 / THE DRAWER
Everything. Under one thumb.
A complete app drawer that behaves like you already know it.
FAST WITHOUT REARRANGING ITSELF
Predictions where your thumb starts. The alphabet where it expects to finish.
Frequently used apps sit in a small predicted band. The full drawer stays alphabetical. Search remains at the bottom, inside the natural reach of one hand.

03 / SEARCH
Two keys. Then done.
Fuzzy, ranked, local, and patient with typos.
ONE FIELD. THE WHOLE PHONE.
Type what you mean. Kern works out where it lives.
Initials find apps. Names find shortcuts. A setting opens as easily as an app. Plain arithmetic stays plain arithmetic.

04 / THE LEDGER
The day, without judgement.
144 marks. Ten minutes each. Nothing hidden inside a score.
A RECORD, NOT A REPRIMAND
Every ten minutes gets one mark. The result is a day you can actually read.
Pickups, longest stretch, time away, first reach, late-night minutes. Kern states what happened and leaves the conclusion with you.

Kern stores the package, the hour, and the outcome. Never the title, text, or sender.
06 / PAGES
A place for the thing in your head.
One swipe from home. Plain text. A small grammar.
CAPTURE BEFORE IT BECOMES AN APP
Notes, tasks, and daily pages without opening another system.
Write in short forms that stay readable as text. Export whenever you like. Lock the workspace when the page is not for everyone holding the phone.

07 / FOCUS
Make one thing the only thing.
Timed sessions, a stricter exit, and a moment to breathe.
FOCUS WITHOUT THE THEATRE
Start a timer. Make leaving deliberate. Stop when you are done.
Regular sessions keep time. Strict mode adds friction to the exit. Breathe gives the space between one block and the next. There is no streak waiting to be protected.

Private by default.
Your apps, notes, searches, and daily records stay on your phone.
Your home screen is not an advertising surface.
Your notes, local search and detailed daily records stay on the phone. Kern has no account or ads. Version 1.1 adds optional Firebase usage and crash reports, plus Google Play and Superwall for paywalls and purchases. Settings can turn reports off or reset local analytics; uploaded records need a deletion request.
