News
Announcements that actually reach people.
Categorized community updates — worship, events, service teams, and matters of the house — with images, reactions, and read signals so nothing falls through the cracks.

Three spaces, one home
News, events, and chat share a single warm surface — built around the rhythm of a community, not the template of a generic app.
Announcements that actually reach people.
Categorized community updates — worship, events, service teams, and matters of the house — with images, reactions, and read signals so nothing falls through the cracks.
A calendar that brings people along.
A shared view of community life with member-only invitations, going / maybe / no responses, locations, and event-tied group chats that start right where the invite lives.
Real-time conversations, in real groups.
Household, service, project, and event groups with threaded replies, image and file sharing, read indicators, roles, and a Socket.IO backbone that keeps flowing even on patchy networks.
The Rózsakerti Baptista Közösség is a close-knit congregation where life happens across conversations, Sunday announcements, shared events, and a steady rhythm of everyday care. As the community grew, that life started to live in too many places at once — scattered across emails, private messages, social media, and in-person reminders — and staying connected became harder than it should be.
Vandslab partnered with the community to design and build a private mobile app for iOS and Android that brings everything together: news, events, real-time group chat, and member management — all in one warm, focused space, available only to approved members of the community.
Before the app, information traveled the way it had for years — spoken on Sunday mornings, emailed during the week, shared in private messages and on social media. It worked, but nothing was truly in one place. Members missed announcements, events lost momentum between channels, and group conversations got buried.
The goal wasn't to build another generic chat app. The community needed something that respected how they actually work: a quiet, private space where only approved members can join, where news and events live next to the conversations about them, and where leaders manage everything from their phones — no desktop dashboard.
On top of that, this is a high-trust environment. Membership is gated, content stays within the community, and the app has to feel safe and personal — not corporate or noisy.

Vandslab built a dedicated native-quality mobile app using React Native and Expo, designed around the community's real day-to-day. News, events, and real-time conversations share a single home — and everything stays private. New members join only after administrator approval.
The news surface is built around real life: categories for worship, events, service teams, and community matters, with images, reactions, and read receipts. Events get the same care — calendar view, RSVPs (going / maybe / no), location handling, and automatically created group chats tied to each event.
At the heart of the app is a real-time chat system built for how this community talks. Groups by household, service, project, event, or topic; threaded replies, image and file sharing, read indicators, mute settings, clear member roles (owner, admin, member). A Socket.IO backbone with auto-reconnect keeps conversations flowing.
Leaders manage the community from the same phone in their pocket. The in-app administration covers member approvals, roles, permissions, news and event editing, targeted announcements, and activity insight — no context switch, just one tool that works wherever the community is.
Built with React Native and Expo in TypeScript, the app ships to both iOS and Android from one codebase. New features reach every member on every device the same day, with consistent behavior across platforms.
Socket.IO powers the real-time layer with automatic reconnection that handles patchy networks and background-to-foreground transitions gracefully. Messages, threads, reactions, and group updates sync instantly across devices.
Every new sign-up goes through administrator approval. JWT-based authentication, role-based permissions (owner / admin / member), and encrypted local storage (MMKV) keep member data safe on the device — closed, personal, community-controlled.
News and events share a flexible data model supporting categories, featured items, images, reactions, and engagement signals. The same architecture powers Sunday announcements and service team updates — evolves with the community without rework.
Expo push notifications keep members informed in real time. Admins can target specific groups or roles, so notifications land with the right people and stay quiet for everyone else.
Expo Updates delivers new versions over the air — improvements and fixes reach every member without a new app store release. The community stays on the latest experience with minimal friction.
The Rózsakerti Baptista Közösség now has a single digital home that matches the warmth of the community it serves. News, events, and conversations live together in one place, protected behind administrator approval, shaped around the way the community actually works.
The app replaced a patchwork of channels with something simpler and more personal. Members open one app instead of four, leaders manage everything from their phones, and the everyday rhythm of the community stays in sync, in one place, and always with the people it's for.
