User reviews

You ruined it.

You people have ruined what once was a great tool. Can not move map to look for other monitor sites. Map keeps coming back to my location. I don’t want alphabetical order I want west to east order like I had it setup before you changed it. Please advise, send phone number for consultation.

Súper

Excellent app

Layout change

I used the old layout style very often (im a fisherman)
Not sure why the layout changed, but I don’t like it. I’d rather know the CFS instead of water height

Very intuitive

Is there a way to add alerts to the app if what you are monitoring surpasses a certain height?

Great app. Responsive developer.

Works just like it says on the tin. Sent in a feedback request and received a thoughtful and personal response rather than a generic “thanks for your suggestion” reply.
