Question about Datel GO-TCHA Evolve for Pokémon GO - Grey

Hello I have bought a Go-Tcha evolve. Unfortunately, it doesn't show me the time and the pedometer function doesn't appear either. Is it correct that there is no app for Android but only the link https://www.go-tcha-evolve.co.uk/webapp/ for settings? There you can adjust very few settings :-(( . Or am I doing something wrong? Thank you for your answer.
