The complete operating layer for kosher devices

Kosher technology has always been a step behind.
That era is over.

KolBo builds the entire application layer of a kosher device — 22 interoperable apps, engineered in-house, secured before they ship — and licenses it to the manufacturers who intend to lead this market.

The applications this market has never had — until now

Anyone can remove features and call it kosher. KolBo builds what the community has been waiting for, from a blank page, to a standard the general market doesn't match.

First in the Jewish world

KolBo Safe

The family safety platform — real-time family location, arrival alerts, and peace of mind, built on kosher infrastructure from the ground up. Parents have watched the rest of the world have this for a decade. Now it belongs here too.

Live family map — every family member, one glance, always current
Arrival & departure alerts — school, home, yeshiva, seminary
Private by design — family data stays in the family, period

First kosher navigation

KolBo Go

Navigation has been the missing pillar of every kosher device — the one app families had to go without, or go around. KolBo Go is turn-by-turn navigation built kosher from the first line of code. Not modified. Not wrapped. Made.

Full turn-by-turn navigation — the real thing, on a kosher device
Compliant by architecture — nothing to disable, nothing to bypass
Works with the suite — one tap from Contacts, Directories, and Safe

The Suite · 22 applications

Everything a device needs. Nothing it shouldn’t have.

KolBo means “everything in it” — and the suite earns the name. Every app below was built in-house on one platform, one cloud, one security layer. Tap any tile and see why no one else can copy it.

Safe

Family safety platform. First in the Jewish world.

The moat

Real-time family location, arrival alerts, and a live family map — the first platform of its kind ever built for the Jewish world. One glance and you know everyone is where they should be.

Go

The first kosher turn-by-turn navigation.

The moat

Every shul and kosher business on earth is built into the map. Full turn-by-turn navigation, kosher from the first line of code — one tap from Contacts, Directories, or Safe.

Search

A proprietary kosher search engine.

The moat

Not a filtered feed sitting on someone else’s index — our own engine, built on open sources, returning clean, relevant results tuned for how this community actually searches.

Browser

The first kosher Chrome, built from the ground up.

The moat

The first kosher Chrome in history — the full Chromium engine, re-engineered in-house with protection fused into the build itself. Nothing to disable, nothing to bypass.

AI

A kosher AI assistant.

The moat

Intelligence with boundaries — a real AI assistant with kosher guardrails engineered in, and safeguards that keep AI out of the wrong hands on kids’ devices.

Phone

Calling, rebuilt clean.

The moat

Open any contact and see every call, every text, and every email with them in one unified timeline. Not even Apple or Samsung ships this. That’s what happens when one company builds all three apps.

Text

Managed, secured messaging.

The moat

Messaging with the security layer built in — and every conversation feeds the unified contact timeline shared with Phone and Mail.

Mail

The first kosher mail client, built from scratch.

The moat

KolBo Mail is built from the ground up — not a reskinned inbox. Spam defense, AI-abuse protection, and child-safe controls are part of the architecture, and it plugs straight into the unified contact timeline.

Community groups, without the account.

The moat

Your favorite community groups, hand-picked and ready to join — without even needing a WhatsApp account. The connection people want, minus the exposure they don’t.

Voice

Dictation & voice notes.

The moat

Speak once, use everywhere — voice flows into Notes, Mail, and Text. And with the custom Hebrew keyboard and kosher video calling, the whole input layer is ours.

Keyboard

Custom Hebrew keyboard + kosher video calling.

The moat

A Hebrew-first keyboard built in-house, paired with kosher video calling — the everyday touchpoints most platforms outsource, we engineered ourselves.

Zmanim

The engine behind the whole suite.

The moat

Zmanim isn’t an app here — it’s a service every other app draws on. The Calendar schedules around it, the Alarm wakes by it, the Library opens to the right daf because of it.

Calendar

The executive calendar.

The moat

An executive-grade calendar with weather and zmanim woven directly into your schedule — you see the day as it will actually be, not just what’s booked.

Alarm & Clock

The alarm with accountability.

The moat

A first anywhere: let a friend or chavrusa lock your alarm so you can’t snooze it (PIN and setup required). Wake up for the daf because someone’s counting on you to.

Weather

Forecasts without the feed.

The moat

Clean forecasts, zero news feed — and integrated straight into the executive Calendar so your schedule already knows about the storm.

Contacts

One contact list — plus every shul.

The moat

Every shul and kosher business, preloaded. One list shared across the entire suite — tap any entry and Go is already navigating.

Camera

Our own camera, protected.

The moat

Built in-house with sight protection in the pipeline itself, and every capture syncs automatically to your KolBo Cloud.

Gallery

A protected photo library.

The moat

Our own gallery, not a stock viewer — synced to KolBo Cloud, where everything is stored and protected under the same security layer.

Player

Your music, from your cloud.

The moat

Prepare any playlist on your kolbo.cloud account and the Player streams it to every device you own. Your library, your rules, our infrastructure.

Library

Every sefer. No internet needed.

The moat

Every sefer, filtered with customizable toggles, fully offline. A complete beis midrash in your pocket that works in a basement, on a plane, anywhere.

Calculator

With a built-in maaser tracker.

The moat

A calculator that knows who’s using it — maaser tracking built directly in. Every calculation of tzedakah, tracked and totaled where the math already happens.

Notes

Notes that follow you.

The moat

Synced through KolBo Cloud to every device, dictation-ready via Voice, and protected like everything else — because one cloud carries the whole suite.

Tap any app to reveal the moat — the part nobody else in the market has.

One platform · One cloud

Twenty-two apps that behave like one product

A bundle is apps sitting next to each other. A platform is apps built for each other. Zmanim drives the Alarm. Weather lives inside the Calendar. Contacts hands a shul to Go. The Camera, Gallery, Notes, and Player all flow through your KolBo Cloud. No one else can offer this — because no one else builds all of it.

One account, one cloud

Sign in once and everything follows you — photos, notes, playlists, contacts. KolBo Cloud is the proprietary backbone that stores it all, protected under our own security layer.

Apps that talk to each other

The unified contact timeline — calls, texts, and emails in one view — only exists because Phone, Text, and Mail share one platform. That's a feature Apple and Samsung can't ship, and our answer to why interoperability is the moat.

One update pipeline, one security layer

The whole suite updates together and sits on the same enforcement layer. Devices in the field stay current, compliant, and protected for their entire life.

For kosher device manufacturers

The devices that ship this suite will define the next decade

A complete application layer, ready to license. Twenty-two apps your customers will compare to nothing — because nothing else like it exists in this market.
Pre-secured and compliant out of the box. Every app ships on our enforcement layer, so your devices clear community standards the day they leave the line.
Flagship exclusives your competitors can't answer. Safe and Go are category firsts. The manufacturer whose devices carry them isn't competing on price anymore.
Wholesale terms, engineering-led integration. We integrate onto your hardware, run the update pipeline, and support the fleet. You ship complete devices.

The security layer

Under everything we build sits security nobody can peel off

The same enforcement layer that protects every KolBo device is available on its own — for any iPhone or Android, for families, schools, and organizations.

Tamper-resistant by architectureProtection is enforced at the device-policy level. Remove the management layer and the safeguard stays locked. Proven on real hardware, not in a slide deck.
AI sight protectionState-of-the-art models screen images, video, and text in real time. Protection at the level of what the eyes see — not just which sites load.
Tiered to each familyFrom encrypted DNS to full-path content inspection — every device configured to exactly the standard its owner requires.
Self-service in minutesEnrollment, configuration, and billing in one portal. No appointments, no technicians, no waiting.

Built in Brooklyn

The kosher world deserves technology built for it — not handed down to it

Every application, every platform service, and every line of the security layer is engineered in-house and proven on real devices before it ships. That's the standard. That's the company.
