Mobile app vs. Web app (SaaS)

Mobile apps are good for

• nonnetwork-intensive application
• precision-relaxed drawing application (due to small screen size)
• hardware-accelerated application
• delay-sensitive application
• strict user interface application
• platform-dependent user group 
• enough storage mobile devices
• high development budget
• trendy requirement

Otherwise, go web apps in the form of SaaS.
