droidBuilding

droidBuilding - 1RM is a fantastic app for Android S.O. that allows you to calculate your 1RM, trace your progress and have all 1RM's organized by date/exercise and see the chart of your progress! Download it for free from Google Store!

For the ones who desires something more there's droidBuilding - PRO! It has all the features that you can find in droidBuilding - 1RM + some mighty perks! You can build your workout plans, log your progress and decide optimal weight to use according to the last 1RMs and execute them at the gym.

It has also an amazing feature: The Workout Player!

It is an easy to use interface that you can use directly at the gym on your device that shows you in a comfortable way what exercises you have to do in a training session, with all the details about reps/weights/rests/exercises. It does also track the times spent for each exercise, notifies you with a sound or a vibration when rest time is going to elapse and finally gives you some infos and statistics at the end of the session.

Workout Player can even work on Wearable devices!

As you can see droidBuilding - PRO is full of smart utilities, so is not for free...but it deserves a lot ;-) Give it a try!
