App recommendation to create /follow HIIT workouts and use a timer etc

[bear78]

Hi! I’m looking for an app to create my own HIIT workouts to do in the gym or at home.

I know the type of workouts I’m looking for. Something like this -

A good mix of strength and cardio.

I’m just not comfortable creating the workouts on my own yet and I don’t really want to do follow along videos in the gym. I want the exercises maybe a demo and instructions about how many sets and a timer.

Thanks!
