Features
PrayCalc uses the shared Ummat account system — one sign-in works across every app in the ecosystem (web, mobile, desktop, TV). Auth runs against auth.ummat.dev (Hasura Auth). The web app keeps the session in httpOnly cookies behind same-origin /api/auth/* proxy routes; mobile stores tokens in expo-secure-store and desktop in a tauri-plugin-store file.
| Tier | Price | What you get |
|---|---|---|
| Free | $0 | Full prayer time calculator on every surface: web, mobile, desktop |
| Ummat+ | $9.99/yr | Everything in Free, plus TV app access and Smart Home integrations |
Ummat+ status is checked server-side wherever it matters — the client never decides who gets Plus. Billing runs through the shared Ummat backend (Stripe + Apple/Google IAP webhooks keep entitlement in sync).
| Surface | Free tier | Ummat+ adds |
|---|---|---|
| Web (praycalc.com) | Sign in/up, saved settings, calculator | Plus badge on the account island, /upgrade checkout flow |
| Mobile (RN) | Sign in/up, calculator, notifications | Pair a TV from Settings > Connect TV |
| Desktop (Tauri) | Sign in/up from the Account tab, calculator | Entitlement badge, link out to /upgrade
|
| TV | — | TV app pairing, account-linked control, and deep display settings are Plus-only |
| Smart Home | — | Google Home / Alexa account linking, device + token routes |
Note: Stripe is not yet provisioned for this account. Until then, /upgrade shows a "launching soon" state instead of a live checkout — nothing charges. Signing in, syncing settings, and using the calculator work today on every surface regardless of tier.
An unpaired PrayCalc TV shows a 6-digit code on launch. A signed-in Ummat+ user adds that TV to their account from any surface, then controls it remotely. No remote control needed after setup — masjids running several TVs manage all of them from one phone or laptop.
Add a TV
- Web: praycalc.com account page, "Add TV" — enter the code shown on the TV screen
- Desktop: menu-bar app, "My TVs" tab — enter the code
- Mobile: Pair TV screen — enter the code
What syncs, and how fast
Once paired, every setting change made from web, desktop, or mobile reaches the TV in about 5 seconds. The TV polls its own settings row on that interval, so there's nothing to refresh or reboot.

| Iqama times | Per-prayer minutes-after-adhan offset (no sunrise iqama) |

Multiple TVs
One account can pair and manage any number of TVs. Each TV keeps its own independent settings.
Mawlid content is excluded from all TV displays.
See also Smart-Home for the TV Command Center on Android TV/Fire TV, which is a separate feature.

A public reference page for schools, universities, correctional facilities, hospitals, the U.S. military, employers, and government agencies on Islamic religious obligations and reasonable accommodation.
-
Multi-year Islamic dates table — Ramadan, Last 10 Nights, Eid al-Fitr, Day of Arafah, Eid al-Adha, and Ashura, computed via the Umm al-Qura calendar (
@umalqura/core). Auto-starts at the current Hijri year and runs 15 years forward, so it never needs manual updates; the current year is highlighted. - Accommodation guidance by topic — Ramadan Suhoor/Iftar timing, the two Eids, daily prayer, halal dietary needs, dress/modesty, Hajj travel, religious property, and end-of-life — each with specific callouts for prisons, hospitals, schools, the military, and employers.
- Authoritative references — EEOC, U.S. Dept. of Education, CAIR, DOJ RLUIPA, Federal Bureau of Prisons (P5360.09), and DoD Instruction 1300.17.
