The App was really simple to use and made us think about the present local wildlife and the state of our local river. Even though it is small it is still vitally important to our local ecosystems.

Great way to really focus on our local river

The apps guidance really allowed me to pause for longer and really look… as a result of pausing longer, I saw a kingfisher on my local stretch of river which I’ve never seen before!
