Focus Shield

Go quiet without
going missing.

Silent mode is all or nothing. Everything gets through, or nothing does, and you spend the evening checking whether you missed something that mattered.

Focus Shield works the other way round. You decide who gets through. Everyone else is quietly held back, and nothing is ever lost.

Three people ring tonight.Everyone else finds you unavailable, and you never had to think about it.
The evening it's built for

It's 8pm. You're finally home.

The phone starts again.

A number you don't recognise. Then a betting text. Then the recovery number about a loan that was never yours, for the fourth time today.

You could switch the phone off. You've thought about it. But your mother might call. Your boss might call. The school might call about your daughter.

So you leave it on. And you keep getting interrupted, all evening, by people who have no business reaching you at 8pm.

Focus Shield exists for exactly that evening.

How it works

One switch. Three things happen.

1

Your people ring

Everyone on your allowed list, everyone in your phonebook, anyone you've called first. Their call arrives like nothing changed.

2

Everyone else waits

The unknown numbers, the lenders, the betting blasts. Your phone stays silent and your evening stays yours.

3

Nothing is lost

Filtered calls still land in your log, tagged so you can see exactly who tried and call them back whenever you want.

You choose the tone

Firmly closed, or politely quiet.

The same shield, two very different messages to the person on the other end.

Hard silence Recommended

The call is dropped the instant it arrives and the caller hears the "not reachable" tone, exactly as if your phone were switched off. Persistent callers give up much faster.

Best for: a nuisance number that will not take a hint.

Soft silence

Their phone rings completely normally. Yours stays quiet. They have no idea they were filtered, so there is nothing awkward to explain the next time you see them.

Best for: everyday focus, family evenings, meetings, prayer.

Either way the call still appears in your log tagged Filtered. Nothing is hidden from you, only from them.

Hard silenceRecommended
The call is dropped instantly and the caller hears a “not reachable” / busy tone, so they stop trying. Best for persistent nuisance and scam callers.
Soft silence
The caller hears normal ringing while your phone stays quiet — they can't tell they were filtered. Discreet, but much the same as leaving your phone on silent.
Either way these calls still appear in your log, tagged “Filtered”, so you can call back. Numbers you’ve fully blocked are silently rejected and never logged.
Two words, one big differenceSwitch between them any time you like.
Smart rules

Nobody wants to build a list by hand.

So Focus Shield works out who you already trust, and keeps that current as your life changes.

Everyone already in your phonebook

If you saved their number, you clearly want to hear from them. They're in, automatically, and new contacts join as you add them.

Anyone you called first

You rang the garage this morning, so of course the garage can ring you back. Wazi notices that and lets them through without you lifting a finger.

Reply to someone and they're in

Answering a message is the clearest possible signal that you want to hear from that person. So it counts.

Verified businesses, as a group

Let your bank, your delivery company and the services you actually use through in one switch, without adding each number by hand.

A word on "Contacts Sync". The switch in the app is named badly, so here is exactly what it does: Wazi reads the phone numbers already saved on your phone and writes them into its own storage on that same phone, so it knows which callers are your people. Numbers only, never names or emails. Nothing is uploaded, there is no copy on our servers, and turning it off clears the list straight away.

Every one of these is a switch you control. Nothing is decided for you, and nothing turns itself on quietly in an update.

Temporary passes

A pass that expires on its own.

You're expecting a delivery. Or a plumber. Or the driver who's about to call from outside your gate. You want that one number to reach you, today, and never again after that.

Give it a pass for an hour, or four, or a day. It removes itself when the time is up, so your allowed list never fills with strangers you no longer need.

  • Pick from your contacts, or type a number in
  • Choose an hour, four hours, a day, or until you remove it
  • Set it for calls, messages, or both
  • A live countdown shows exactly how long is left

There's a temporary block too, for the number that's having a very persistent day.

The honest bit

"But what if I miss
something important?"

That's the right question to ask, and it's the one Focus Shield was designed around. Four answers.

A real emergency still reaches you

If the same number calls twice within three minutes, Wazi lets the second one ring. That pattern almost never means a salesperson. It means somebody is trying urgently to reach you, sometimes from a stranger's phone.

Nothing is hidden from you

Every filtered call appears in your log, tagged so you know why. You can see who tried at 9pm and call them back at 9am. The shield keeps them out of your evening, not out of your life.

Your people were never at risk

Everyone in your phonebook is allowed automatically. For Focus Shield to block your mother, you would have to not have her number saved.

One tap turns it off

It's a switch at the top of the screen, not a setting buried six menus deep. Expecting an important call from a number you don't have? Turn it off for an hour.

Who turns it on

Different lives, same relief.

The student in exams

Three hours where only family and the department can reach you. Everything else waits until you walk out.

The one in back-to-back meetings

Clients ring through. Betting blasts don't. And you never had to remember to switch anything on, because open hours did it.

The one at prayer

An hour of genuine quiet, without the guilt of being completely unreachable if something happened at home.

The one expecting a delivery

A pass for the rider's number that vanishes by itself tonight, so tomorrow's list is as clean as yesterday's.

The shop owner after hours

Customers reach the shop between 8 and 6. After that, the phone belongs to the family again.

The one being harassed

A lender chasing a debt that was never yours. Hard silence, and they hear a dead line every time until they give up.

Take your evening back

Your phone.
Your rules.

Focus Shield is in the free version. No card, no trial, no catch.
