I doubt an app could damage the card, heat possibly could, a drop, or sometimes electronics are just defective or go haywire for no reason. I think its worth the extra money to invest in a good quality card, but that's no guarantee, either. Best bet is to back up data frequently if you have some important stuff on there. Micro SD cards are not the most reliable storage device.
