Focus, measured
Train your focus like a muscle.
Locked times how long you actually stay locked in, shows you when you drift, and lets your friends see you working. Built by two Berkeley students.

How a session works
One tap is the whole interface.
No pomodoro rules to follow. You work as long as you can, and Locked keeps an honest record of it.
-
Step 1
Lock in
Name your priority, set a goal if you want one, and start. Your screen goes dark and the ring starts filling.
-
Step 2
Tap when you drift
Reached for your phone? One tap pauses. Another tap gets you back. Pause and resume from the Lock Screen too.
-
Step 3
See your flow
Every session ends with your focused time, your longest unbroken stretch, how often you drifted and a flow curve.
After every session
Numbers you can train against.
Locked shows a few plain measures, so you can see your focus getting stronger week by week.
- Focused
Time you were locked in, with pauses taken out.
- Longest
Your longest unbroken stretch. This is the one to grow.
- Drifts
How many times you broke off. Fewer drifts, deeper work.
- Flow
A 0–100 score that climbs the longer you stay unbroken and dips when you drift.
Better with friends
See who's locked in right now.
When three of your friends are working, it's harder to open Instagram. Locked shows who is focusing, what they're on, and what they finished.
Live status
Friends see a green dot while you're in a session.
Feed and hearts
Finished sessions land in your friends' feed. Leave a heart or a comment.
Streaks and recaps
A daily streak, plus a day and week recap of where your hours went.
Brain dump
A thought pops up mid-session? Swipe it into the brain dump and keep going.
The Berkeley beta
We're onboarding 75 students this fall.
We set you up in person, you use Locked for real study sessions for four weeks, and you tell us what works and what doesn't.
- Founding perks for everyone who finishes the four weeks.
- A Founding badge on your profile that nobody else can get.
- A direct line to the two people building it. Your notes decide what ships next.
Or find us tabling on Sproul Plaza.
Questions
Before you sign up
What phone do I need?
An iPhone on iOS 18 or later. There's no Android version yet. If you're on Android, join the waitlist anyway so we know you're out there.
Is it free?
Yes. Timing sessions, your stats, friends and the feed are free. Beta testers who finish the four weeks get founding perks when we launch.
Does it block apps?
Not yet. App blocking is built and waiting on Apple's approval. A Mac app that blocks distracting apps and sites during a session is on the way too.
Who sees my sessions?
Your finished sessions show up in your friends' feeds, and theirs in yours. Brain dumps stay private to you.
What do you do with my data?
We use it to make Locked better, and we never sell it.
