About this app · Built by Z&D
One masjid app.
One masjid app.
Every device. Any city.
The Jackson Heights Islamic Center website and its native apps for iPhone, iPad, Mac, Android and Windows run on one platform. It can be set up for your center's location, prayer calculation, name and colours, and every app keeps working without a connection.

See it as your center, right now
Pick a city, a calculation method and a colour. The phone below works out today's real prayer times for that place in your browser, using the same calculation the apps use when they are offline.
That is the whole difference between two centers: the site values drive the website, the admin console and every native app, and the theme sets the colours.
One codebase, many centers
Reproduced for every location, each with its own look
Each center gets its own copy: its own website, admin console, database and store listings. The times below are calculated live for each city.
Native on every platform
Not a website in a wrapper. A real app on each device.
Each app is written in the language its platform was designed for, so it opens fast, scrolls smoothly, follows the device's own design and works with its notifications, calendar and maps.
Mac
Swift · SwiftUI- Next prayer and countdown in the menu bar
- Sidebar window, ⌘R to refresh, ⌘, for settings
- Runs in the macOS App Sandbox
- Same database design as iPhone
Android
Kotlin · Jetpack Compose- Material 3 in your colours, edge to edge
- Bottom bar on phones, side rail on tablets
- Background refresh with WorkManager
- Adhan reminders that survive a restart
- Small, optimised release build
Windows
C# · WinUI 3 · .NET 10- Windows 11 look with the Mica background
- Side navigation, F5 to refresh
- Prayer reminders as Windows notifications
- Remembers its window size and position
Website & admin
Python · FastAPI · SQLite- Fast pages, no heavy frameworks
- Admin console for the committee
- Live prayer countdown and adhan
- Donations, contact, newsletter
One shared contract
Same data, same rulesAll the apps follow one written specification and are checked against the same prayer-time test data, so a time shown on Android is the time shown on iPhone, Mac, Windows and the website.
Always fresh, never stuck
Every device has its own database
The committee updates the site once. Every app picks up the change by itself and keeps a full copy, so it opens instantly and keeps working underground, on a plane, or when the Wi-Fi is down.
- Ready on first launchThe current content is built into the app, so it is complete even with no internet.
- One request to refreshOn launch, every few hours in the background and when you pull to refresh. If nothing changed, almost nothing is downloaded.
- A month of prayer timesAbout 30 days are stored on the device; if those ever run out, the app calculates the times itself.
- Messages wait their turnContact and newsletter forms are saved on the device and sent as soon as it is back online.
Made yours
What every center can change
Location & prayer
Coordinates and time zone, 10 calculation methods, Hanafi or standard Asr, iqamah offset, Jumu'ah times. Every time can still be set by hand.
Brand & design
Name and wordmark, colours, logo and app icon, hero photos and wording. A new look comes from settings and one theme, not new code.
Content
Events, causes and fundraising goals, announcements, team, programs, gallery, sermons and testimonials, all in the admin console.
Donations
Your own PayPal donate button on every page and in every app; fundraising progress bars update with the site.
Reminders
Optional adhan reminders for each prayer, scheduled on the device itself, with the real adhan in the prayer details.
Your domain & stores
Your web address with HTTPS, and the apps listed on the App Store, Google Play and the Microsoft Store under your organisation's own name.
Your center, live
Four steps from first call to the app stores
- 1
Tell us about your center
Location, calculation method, iqamah practice, Jumu'ah, your logo and colours, and what you'd like on the site.
- 2
We set up your brand and content
We configure the platform, bring over the content from your current site, create your logo files and app icons, and load your events and causes.
- 3
Try it on your own phones
Your committee gets test builds for iPhone and Android, and the Mac and Windows apps, plus a private preview of the website.
- 4
Go live
The website goes online on your domain with HTTPS, and the apps are submitted to the stores under your organisation's accounts.
Full tech team support
A team behind your app, not just a download
Z&D built this platform and looks after it. Your committee runs the center; we keep the technology running.
Talk to the team- Setup & migrationConfiguration, branding, content import and store listings handled for you.
- Hosting & updatesCloud hosting with HTTPS. Every update is checked after install and rolled back automatically if it fails, with a database backup taken first.
- New OS versionsThe apps are kept current with each year's iOS, macOS, Android and Windows releases.
- SecurityProtected admin sign-in that locks out repeated wrong passwords, strict security headers, and no secret keys inside the apps.
- TrainingYour committee learns the admin console: prayer times, events, causes and messages.

Data syncOne JSON document at

Speed goalUnder one second from tap to today's prayer times; network work starts only after the first screen is shown.
Questions
Common questions
Does our center need its own server?
The website runs on a small cloud server or in Docker; we can host it for you. The apps don't depend on it: they work offline and refresh from your website whenever they can reach it.
Can we keep our own iqamah times?
Yes. Adhan times can be calculated automatically every day, while iqamah follows a fixed offset or is entered by hand by the committee. Jumu'ah is always set by you.
We have several locations. Can each have its own app?
Yes. Each location gets its own settings: coordinates, calculation method, name, colours and content. The apps are built from the same code, so a new location takes a set of settings, not a new project.
Who owns the data and the store listings?
You do. The content is a single SQLite database that you can download at any time, and the apps are published under your organisation's developer accounts.
Is there advertising or tracking?
No. There are no adverts, analytics or trackers. The apps download data only from your own website and the AlAdhan prayer-time service; maps and video thumbnails come from the device's own maps app and YouTube.
