App, PWA and push
People receive and answer notifications at app.notific.me, in English, Portuguese or Spanish. It is a web app that can be installed like an app (a PWA) on phones and computers, and it works with alerts even when closed. Native iOS and Android apps come next.
Install the app
Section titled “Install the app”- Open app.notific.me and sign in.
- Tap Install on the invite that appears, or Install app in the menu (or the browser’s install icon in the address bar).
- Open notific.me from your home screen or app list.
- Open app.notific.me in Safari and sign in.
- Tap Share (the square with an up arrow) in the toolbar.
- Scroll and tap Add to Home Screen, then Add.
- Open notific.me from the home screen.
On iPhone, alerts with the app closed work from iOS 16.4, when the app is opened from the home screen.
Turn on notifications
Section titled “Turn on notifications”- In My notifications, tap Turn on in “Get alerts on this device”.
- Allow notifications when the browser asks.
- In Devices, use Send test push to check that it works.
If you blocked notifications before, allow them again in the site settings of your browser.
How delivery works
Section titled “How delivery works”| Situation | Path | Latency |
|---|---|---|
| App open | WebSocket gateway | Tens of milliseconds |
| App closed (PWA) | Web Push (VAPID, encrypted end to end) | Usually 1 to 2 seconds, no guarantee |
| App closed (native) | APNs (iOS) or FCM (Android) | Usually 1 to 2 seconds, no guarantee |
| App opens again | Incremental sync from a cursor | Immediate |
- Because Web Push is encrypted end to end, it shows the title and summary. Native pushes carry the minimum, and the app fetches the content.
- Tapping a push opens the notification or the decision directly.
- A subscription the push service reports as expired is removed from the device automatically.
- Signing out removes the Web Push subscription of that device (shared computers).
Devices
Section titled “Devices”Devices lists every phone and browser signed in to your account, with push status and last seen. You can rename a device or revoke it: it is signed out and stops receiving notifications immediately.
Deciding in the app
Section titled “Deciding in the app”- The inbox highlights what is waiting for your decision.
- Each decision shows the card, the questions and the required level.
- On the web app, levels 0 and 1 need only your session. Levels 2 and 3 need the 2FA code, and level 2 can use your 2FA window. Level 4 (quorum) needs the native app.
