Quell the noise.
Find your calm.

Quell sorts your notifications by itself — promotions are muted into one quiet group, messages come straight through, and what's urgent stands out. All of it on your phone. None of it anywhere else.

01

See the triage happen

A morning's worth of notifications, sorted in seconds. This demo runs entirely in your browser — the same way Quell runs entirely on your phone.

Messages pass through

People always reach you. Quell never touches a real conversation.

Promotions go quiet

Sales, campaigns and "we miss you" pings are swept into one silent group you can always reopen — nothing is ever deleted.

Urgent stands out

Deliveries, banking alerts and emergencies get flagged — never buried, never lost.

// no servers involved. not now, not ever.

// live

Try the triage yourself

Type any notification — the same kind of triage runs right here, in your browser. Nothing is sent anywhere.

Simplified for the web — the real Quell runs deeper rules, fully offline on your phone.

02

Calm, engineered

No rules to write, no filters to maintain. Quell works from the very first notification.

Automatic triage

Every notification is classified in real time: personal, transactional, promotional or urgent — right on your phone.

Mute promotions

Marketing lives in one silent bundle you can clear with a swipe — or ignore forever.

Urgency detection

Deliveries, banking and emergency alerts are recognised and surfaced — the things you can't afford to miss.

Local history

Review what was sorted and why, for up to 30 days. Stored only on your device, excluded from cloud backups.

Built to be trusted

If anything can't be sorted safely, Quell leaves it visible. Losing a notification is the one thing it refuses to do.

Offline by design

Quell declares no internet permission. Your notifications physically cannot leave your phone.

03

Privacy is not a setting

Most apps promise not to misuse your data. Quell goes further — it can't. With no internet permission in its manifest, there is no pathway for your notifications to go anywhere. That's not policy. That's physics.

Verifiable

Check the app's permission list yourself: no internet. The claim is auditable by anyone, anytime.

Nothing collected

No analytics, no trackers, no crash uploads, no accounts, no fingerprinting. The Play data-safety label reads: none.

Yours to delete

History lives in local storage for 30 days, excluded from cloud backup. Uninstall, and every trace is gone.

Quell works in airplane mode. Forever. Try that with any cloud app.

Questions, answered

When can I get it?+

Quell is entering closed beta on Google Play. Request an invite by email and you'll get the opt-in link as soon as the beta opens.

How much will it cost?+

One single purchase at launch — no subscription, no ads, no "premium" upsell. During the beta, Quell is free for testers.

Which languages does it understand?+

Quell ships with English and Portuguese, and its triage understands notifications in both.

Why Android only?+

Only Android gives apps a supported way to manage notifications (the notification listener API). iOS doesn't — so a genuine Quell for iPhone isn't technically possible today.

What does Quell read, exactly?+

The content of incoming notifications — that's what sorting requires. It is processed on-device, kept at most 30 days in local history, and never transmitted. The full details are in the privacy policy.

Your phone, finally quiet.
