Last Gart event sent … seconds ago.

Gart alerts and check-ins travel over public Nostr relays. This page reads those relays straight from your browser. Anyone can see that an alert went out and when. The content is ciphertext that only the sender and the Responders can read.

Source: public Nostr relays, read by your browser since you opened this page. Each figure counts only what the relays reached still hold.

Last 30 days

Alerts and check-ins per day.

Alert events (kind 694) Check-ins (kind 313)
Relays

Relays transmitting Gart.

The same event often goes through several relays and is counted once.

Method

Read the figures as a lower bound.

Relays delete old events on their own schedule, so the figures above count only what they still hold. When a relay does not answer, its events are missing from the total, and the third figure says which relay is missing.

The total reads seven relays: the five listed here, which the Gart app sends to, and nostr.oxtr.dev and relay.nostr.net, which keep older Gart events that the app's relays have deleted.

The figures count events. An alert sends a start, location updates and a stop, and each of them is one event.

Feed

Every alert is encrypted.

Only your Gart Responders can read it. They hold the decryption key.
