Open Lingua Sacra on the webFree tier on every platform. No install, no credit card. Optional Full Access is $9.99/year or $39.99 lifetime.
Why a web version?
Lingua Sacra started on iPhone and Android, where the core learning path still works offline — on commutes, in the confessional line, during Mass prep in spotty rectory Wi-Fi. But plenty of Catholics who want to learn Latin are at a desk: seminarians studying for morning office, homeschool parents preparing tomorrow's lesson, choir directors marking up hymn translations.
For them, waiting to get home to their phone was the wrong friction. So the full app now runs in any modern browser — same lessons, same Vulgate reader, same spaced-repetition system, same crown levels. A single Supabase account ties it all together: start a lesson at your desk, finish it on your phone on the way to adoration.

Pricing
Lingua Sacra is free to use on every platform. Every account gets a permanent free tier: the first 10 of 202 lessons, the four core prayers (Pater Noster, Ave Maria, Gloria Patri, Signum Crucis), Vulgate Genesis and the Gospel of John, the Liturgy of the Hours, and the Mass companion. Full Access — every lesson, every prayer, the full Vulgate, every recording, every practice tool — is an in-app purchase: $9.99/year (auto-renewing subscription) or $39.99 one-time for lifetime access. Both options grant the same content and restore to the same signed-in account across iOS, Android, and the web.
On iOS and Android, Full Access is purchased through the App Store or Google Play in-app purchase. On the web, in-app purchase is rolling out shortly; for now the web app uses the same signed-in account, so anyone who already has Full Access on iOS or Android will see it unlocked on the web automatically. No free trial, no ads, no upsells.
Frequently asked
Is this the same app, or a trimmed-down version?
The same app. Same 202 lessons, same Vulgate chapters, same prayers, same crown system, same spaced-repetition review queue. The web build is a React Native Web compile of the iOS/Android codebase, so content parity is automatic.
Does my progress sync?
Yes, as long as you sign in with the same account. Create an account on the web and your XP, streaks, and SRS cards appear on iOS and Android on first login. The reverse works too.
What about offline?
The web app needs a connection. If you want fully-offline Latin — underground parking garages, airplane mode, rectory Wi-Fi outages — install the iOS or Android app. That's what they're built for.
Where does web payment happen?
Web in-app purchase is rolling out shortly via RevenueCat's hosted checkout. Until it lands, the simplest path to Full Access on the web is to buy on iOS or Android (App Store / Google Play in-app purchase) and sign in with the same account — the entitlement restores automatically on the web. No free trial is offered on any platform; no credit card is required for the permanent free tier.
Which browsers are supported?
Any modern evergreen browser: recent Chrome, Safari, Firefox, or Edge. Audio playback uses standard HTML5, so no plugins or extensions are needed.
How do I get a refund?
Web purchases go through Lemon Squeezy, which handles refunds within 14 days for any reason — reply to the purchase confirmation email. Mobile refunds go through the App Store or Google Play per their own policies.
