Depth Watch
Depth Watch lets you track how deep the water is at spots you care about - a dock, a boat launch, wherever - calculated automatically from the live sensor reading. Sign in to set it up; your spots are saved to your account and follow you to any device.
You'll sign in directly with Google or Microsoft on their own site - we never see or store your password.
The blue pin marks the sensor. Tap the orange pin icon in the bottom-left of the map, then click where you want to track depth (tap it again to cancel). Pins stay put otherwise - tap Edit on a spot below to drag and fine-tune its location. The locate icon in the bottom-right shows your current location on the map, handy for placing a spot near where you are. Click any pin to see its current reading.
Give each spot a name, then enter the date, hour, and depth you measured there. We'll calculate every spot's current depth automatically. Everything here saves to your account as you go.
