Android Gym App Suggestions

I've recently started back at the gym (this may explain the recent fracking reports around Glasgow!).

Previously I had used Samsung Health, but for reasons known only to Samsung they have over complicated the interface, and removed the facility where you could arrange the various exercises as per your routine. When you finished one exercise, it opened up to your routine and you chose the next exercise, and so on.

Now you have to choose Start, go down the list of various exercises, open it up and off you go. And you have to do this for every exercise. I also cannot find a way to arrange them as per a routine. 

So, if anyone could suggest a gym oriented app that has;

the flexibility to arrange exercises to a routine.

Record what weight(s) I'm using on a piece of equipment,

Record distance and time goals for treadmill and exercise bikes. 

That would be greatly appreciated.
