01What we build

Apps across every dimension of life.

Intelligent software should serve every human need — spiritual, recreational, practical and protective. Each category below is one we have actually shipped into.

01

Religious & Spiritual

Liturgical calendars, fasting companions and prayer tools built with content accuracy as the first requirement.

02

Security & Privacy

On-device scanning and breach detection. Tools that protect data without collecting it themselves.

03

AI & Companions

Model-backed assistants with memory and context, wrapped around a deterministic system of record.

04

Games & Puzzles

Mechanically honest games. Prime Lock turns number theory into something people play voluntarily.

05

Productivity & Utilities

GPS tracking, trip logging and everyday tools engineered to be correct before they are clever.

06

Environment & Awareness

Apps that make invisible systems legible — and give people something concrete to act on.

03How we work

A process built around shipping, not slide decks.

Four phases, run in the open. You see working software early and know exactly what happens after launch.

01

Discover

We map the users, the constraints and the one sentence the app has to answer before anything is designed.

02

Design

Prototype first, including the disconnected and empty states. Validated before production code exists.

03

Build

Agile cycles on a shared foundation. Working software early, reviewed against store policy from day one.

04

Maintain

Release is the start. OS updates, policy changes and support are an ongoing commitment, not a phase.

04Why Zecrari

Three commitments we do not trade away.

These are not positioning statements. They are constraints that have cost us features and revenue, and they are the reason our apps behave the way they do.

01

Offline-first by default

The answer a user opened the app for resolves on-device. Networks are treated as optional, never assumed.

02

Collect nothing you don't need

Privacy Lens classifies apps on the device itself. Catholic Calendar collects nothing at all and carries no advertising.

03

One foundation, many products

Shared networking, storage, consent and release infrastructure — so a platform change is fixed once, not six times.

06From the blog

What we are learning.

Engineering writing from the people doing the work — not a content marketing pipeline.

07FAQ

Questions we get asked.

Something not covered here?

hello@zecrari.com

Our products currently ship on Android via Google Play. iOS is the most frequent request we receive and is on the roadmap — we are building the shared foundation first rather than porting six apps independently.
