fitness app (strength)

The first thing that came to mind for me was Fitocracy. Knowing nothing about apps I did a quick google search and the site says that an Android app is coming. If so, I'd recommend! I love that site, has a lot more exercise/strength related stuff and levels.

Jefit is a well application for strength training - but may be a bit more 'advanced' than you're looking for.

I use and quite like Fitness Buddy. The paid version has over 1700 exercises in its database, with pictures and descriptions about how to do each one. It has an entire section of body weight only exercises for all body parts. You can use the library to custom build your own workouts, or you can choose from a very generous selection of on board workouts, including some workouts that consist exclusively of body weight exercises. You can even enter your own exercises if you have some that you enjoy but that aren't included in the 1700 exercises.

I've used it to assemble and track several different types of workouts from heavy lifting, to crossfit type workouts. You can also track cardio workouts (running, cycling, rowing, etc.), though I much prefer Endomondo for tracking these workouts. It also gives you a place to record your weight and host of other body measurements (biceps, chest, waist, etc.)

It's very easy to record and recall workouts so you know exactly the weights and reps you've done before. It's a very good tool to aid you in making sure you are progressing, for the most part.

It has weaknesses, however. It frequently crashes. I thought perhaps it was my phone, but I've ready many others who complain of the same issue. It's not necessarily fatal when it crashes. I just start it up again and it runs fine. I've never lost any data when it crashes, so it's mostly just a nuisance.

I also wish the exercises in its database that are more suitably tracked by time and reps offered this option. All of the exercises in its database force you to track them as weight and reps which just doesn't fit some of the exercises. If you custom create the exercises, you have many options as to how to track them, but the ones that come native to the application can only be tracked as weight and reps (except the cardio exercises). I also wish the app would generate progress charts for custom exercises, as it does for the native exercises. It will generate a printed history of all exercises, custom or native, but only the native exercises can be charted.

I also wish it had a companion website like Endomondo where everything is uploaded. I worry that if I lose my phone to theft or accident, I will lose all my data. I do back it up to my laptop using MobileGo, but it isn't an automatic process. I have to remind myself to back it up, and my memory is hardly a reliable application. But even with its warts, I really like app and use it almost daily.

I use gymrat for tracking what i do on what days etc, its got some good features.

Are you looking for something to tell you what to do or just to track what you are doing? I would recommend doing a proven lifting routine and tracking it with.....dunt dunt duhhhh, My Fitness Pal.
