Its not one of the best... It is the BEST app out there. I have been using it for over a month now and its quick and easy to track the workouts and put extra pounds on the barbell or shoot for more reps if you know it. Bravo Gym Hero!! Only thing lag behind is you have to buy the pro version to get the version. But thats alright! Totally worth it! Cheers
