River Pulse

Zoomable geographic context using official Environment Southland station positions. Select a layer, then click any marker for its exact reading and report time.

Use your phone to photograph a repeatable local reference. The app saves the photo, capture time and phone GPS accuracy beside an official-gauge snapshot. It does not infer the local water level.

Test record — I am not at the calibration siteUse this when checking the phone workflow elsewhere. Test records never affect calibration maturity, the pulse marker or the map, and can be deleted after checking.
