ntfy is a free, open-source notifications app we use to push card alerts straight to your phone the moment we spot something. No account, no spam, no tracking, it simply delivers your alerts instantly. You can use push, email, or both.

1. Install ntfy: iPhone (App Store) or Android (Google Play).
2. Open it and tap + Subscribe to topic.
3. Paste your private topic below and tap Subscribe. That's it, alerts now arrive as push notifications.

This topic is unique and private to you, and you'll only ever get alerts for the cards you choose to track.
