Workout planner/tracker app

Hey guys,

I am trying to find a good app for workout planning and tracking. I am currently using Strong, which works well for keeping track of my workouts, but planning workouts ahead of time seems to be out of scope for that app.

The background for this is that I want to change my routine to wendler 5/3/1 and I want to have the app tell me the amount of sets and reps as well as the weight that I am supposed to use.

I hope my request makes sense for you guys, I am sure there's something out there matching my needs.
