* A moment that’s yours
Make room to think
Protect a stretch of quiet, everything else can wait.
Umbral locks the apps that pull you away for as long as you decide, so you can cross into focus instead of circling it all morning.
Free · iPhone & Android


* The threshold
Concentration has a threshold.
Crossing it takes about fifteen minutes.
There’s a point where the work stops being effort and starts pulling you along, where you look up and an hour has gone.
That state has a name, and it has a door.
Getting to it takes roughly fifteen minutes of uninterrupted attention.
Leaving it takes one glance at your phone.
That’s the trade nobody does the maths on: checking a notification doesn’t cost you thirty seconds, it costs you the fifteen minutes you’d already spent climbing, and the fifteen more it’ll take to climb back.
Umbral is named after the threshold.
Flow is the one worth crossing.

* Flow
Choose the apps.
Choose how long.
They’re gone.
No countdown to stare at, no motivational nudges, no streak begging you not to break it, just the door closed and the room quiet.
25 min
A first push, enough to start, not enough to fear.
50 min
One full block, you’ll cross the threshold with time to spare.
90 min
Your attention already works in cycles about this long, this is one of them, protected.
180 min
A morning, for the work that only happens when nothing can reach you.

* Escapes
Three a day.
Each one costs you.
An escape is 30 points off your balance.
That isn’t a punishment for weakness, it’s the actual price, made visible: leaving doesn’t cost you a minute, it costs you the climb back.
Umbral just puts a number on what you were already paying.
There’s also an emergency exit: it ends the session and wipes that week’s points, never your balance, which you earned.
It exists because real emergencies exist, and it’s meant to feel like one.
* Routines
The same threshold, without deciding every day
Set the hours when certain apps are simply unavailable: weekday mornings, dinner, the last hour before bed.
They work exactly like Flow.
The difference is you set them once and then stop having the argument with yourself.
* Thresholds
For the rest of the day, a pause instead of a wall
You won’t block everything, all day, nobody does.
So for the apps you keep, Umbral holds the door instead of closing it.
Open one and it makes you wait: thirty seconds the first time, longer with every entry that day, up to five minutes, then five real minutes of use before it closes again.
It isn’t a block, it’s the half-second of thought the app was designed to skip.
Most of the time you’ll close it before the wait is over, and Umbral keeps count of those.
Focus isn’t a hack.
It’s a practice.
* Wild Balance
The time you spend on the other side turns into products
Every minute of focus earns a point.
Points become euros at Wild Fuel, real plant-based products, not badges.
Every minute on the other side

Every session you finish

A clean week, 60 minutes, no escapes

300 points = €1 · coupons start at €5, so 1,500 points is your first one
What that looks like in practice: an hour a day, five days a week, no escapes, about 595 points.
Points never expire, so two and a half weeks like that is a €5 coupon off your next order.
Up to €30 a month.
Points don’t expire, a coupon does, seven days after you claim it.
* What we see
Nothing.
Your app selections and your stats stay on your iPhone.
Umbral never sees what’s inside the apps you block, not the messages, not the feeds, not what you do in them when it isn’t watching.
Screen Time is the only permission it asks for.
It’s Apple’s own system, and it’s what lets one app lock another without reading a word of it.
A Wild Balance needs an account, an email and a name.
Without one, Flow, Routines and Thresholds work exactly the same.

Quick answers for curious minds
Learn how Umbral works, and how it pays you back.
Is it free?
Yes. The app costs nothing and there’s nothing to unlock inside it.
Do I need a Wild Fuel account?
Only to collect points. Flow, Routines and Thresholds work without signing in.
What if I really need to get out of a session?
Three escapes a day, 30 points each. Plus an emergency exit that clears the week’s points, not your balance.
How long until I’ve earned something?
An hour a day on weekdays gets you to a €5 coupon in about two and a half weeks. Points don’t expire, so slower still gets there.
What happens to my points if I stop using the app?
Nothing. They stay. The coupon you claim with them expires after seven days.
Does it block calls or messages?
No. Only the apps you pick, and only when you say so.
How do points become products?
Every minute of focus earns a point. 300 points = €1 at Wild Fuel. Coupons start at €5, so 1,500 points is your first one, up to €30 a month.
What does Umbral see?
Nothing. Your app selections and your stats stay on your phone. Screen Time is the only permission it asks for.
