Can one assume the apps on the Sprint software store are compatible to device?

I've had my Sprint HT Pro for almost two weeks. While browsing the programs, I clicked on an icon for the Sprint software store. It displayed a lot of apps I've never heard of, and some I have. My question is: is it safe to assume any of the mobile apps displayed in the Sprint store on my device are compatible with the HT Pro? What if they're not? If I attempt to download one that isn't compatible, will I be notified during the install? Should I just browse for apps outside my device and do the installation by USB cable? Thanks!
