Best Bodybuilding app.

So. my N4 is finally shipping.
Hooray for me.

I am currently using Jefit, but am wondering if there might be a better option for android. Ive heard of gymrat, but havent ever used it as I am on iphone right now.

What it needs to have:
The ability to easily and quickly reorder the exercises in a muscle group you are currently working out.
The ability to quickly tell you what you last lifted last time you worked that exercise.
The ability to easily create your own exercises
An easy to navigate UI

What I would like it to have:
Only shows routine to work if you have not worked that routine in the past 5 days.... or at least tells you when you last performed X routine.
The ability to track how far you have run/ hiked (may need a different app for this one)

Very simple to find it in Apple store.. same kind of apps according to your requirements Such as Easy Gym Log, Body Shop Fitness App, Daily Leg Workout, Gorilla Workout and Fitness Tips.

GymGoal ABC helps newbies learn the basics of bodybuilding.
This app consists of a data source of over 280 workouts described in written guidelines and cartoon cases. It also includes a minimum of 39 strength-training workouts and about 24 aerobic workouts.

Fitocracy works well and has tracking capabilities on thier website also
If you want to have a workout made for you:
Bodbot - free and very easy for beginers to get a workout in and start lifting.

Best weight lifting app for serious lifters or people on a legit program that has tracking capabilities?
Google drive.
I upload my 5/3/1 spreadsheet and track it all through there, and it has pages for each month(12 before you reset) as well as each week's liftings schedule.
I open drive, and google music strap the phone to my forearm, fire up the BT headphones, and it's my world for 2 hours every day.

You should check out GymProvise ([Only registered and activated users can see links. Click Here To Register...]). It is a paid app that's a Workout Tracker, Workout Planner, Exercise Directory, Progress Tracker and general fitness companion.

It's got 350+ exercises with images and instructions, lets you setup your Training Program in minutes, supports advanced training techniques like Supersets & Dropsets, and enables you to easily track your Workout in real time with many tracking features e.g. Rest Timer/Stopwatch. It also has a bunch of great Charts to see your progress, and lets you post summaries of your Workouts to Facebook, if you choose.

All of the "need to have" features stated by the OP (exercise reordering, view last logs easily when tracking, creating custom exercises, intuitive UI) are built into the app.

It was designed and built by a small group each of whom have more than 10 years of training experience. We know our way around a Gym and we think that is pretty well reflected in the app. We also know that a bodybuilding/fitness app should not disrupt or intrude into Workouts by being cumbersome and difficult to use, otherwise it defeats the purpose of said app.
