Sigtrail

See when your connection is really slow, on Wi-Fi and on mobile data. Everything stays on your iPhone.

Status: in development and testing. Not yet on the App Store.

What it does

Measures latency, jitter and packet loss, and gives a 0 to 100 quality score.
Keeps a history with charts, so you can see patterns such as a slow commute hour.
Home Screen and Lock Screen widgets, and a Live Activity for the Dynamic Island.
Phone heat tracking using the four levels iOS reports (not degrees).
Optional map of where your connection was weak, with location rounded to about 220 metres.

Privacy first

All history is stored on your device. Nothing is uploaded.
No accounts, no ads, no analytics, no third-party SDKs.
Location is off until you switch it on.

Good to know

iOS does not expose signal bars or dBm, so Sigtrail judges quality from the radio type and measured latency.
Widgets refresh when iOS allows, so they are not live.
Requires iOS 17 or later.
