I’ve been using Noom Walk for almost a week. I’ve found it to be a useful little Android App, and I think you might like it too.
What is Noom Walk?
Noom Walk is a pedometer simulator for Android smart phones. I’m running it on the Evo 4g. I haven’t been able to find anything to explain HOW it works, but I’m assuming that the Evo’s sensor that determines its orientation is probably the mechanism that’s also used to count steps. If anyone knows better, please correct me in the comments.
How well does Noom Walk work?
Noom Walk’s description says that it uses very little battery power, but I’m seeing that it’s using a noticeable amount on my phone. I love the Evo, but it’s not exactly known for getting great battery life anyway, so that may be an issue more with this phone than with others.
As for accuracy, Noom Walk seems to be counting me a little on the low side. It’s nothing big, and it’s really no more inaccurate than some pedometers I’ve owned. I carry my phone in my pants pocket, so users who carry it in a case on their belt may see better accuracy than I am.
Noom Walk setup
Setup and use is super easy. The simplicity is one of the nice features of the app. There’s nothing to tweak and fiddle with really — just an app that does what it says it’s going to do.

As you can see, you fill in a few questions so Noom Walk can be more accurate, and you’re set. Noom Walk will run in the background and count your steps. It’s also smart enough to reset itself daily.

You can open the Noom Walk widget and view this screen, which gives you your steps, approximate miles, and calories burned. Noom Walk also keeps a history of how you’ve done, which is also a nice little feature.
Conclusion
Noom Walk is a great little free application to help you track your activity daily. Since my surgery, walking is just about the only exercise I’m allowed to do for now, so this application is great for me. I can estimate my daily steps without having to remember to wear a pedometer. If you’re like me, you’re much more likely to remember your cell phone!
