Native Mobile Review
Ranked in these QuestionsQuestion Ranking
Pro No servers
Depending on what you are developing of course, but for apps that stand alone, not having to run up or maintain web or other servers can be a bonus as developers can work anywhere with nothing more than their development environments.
Pro Slicker UIs
The web has progressed greatly but mobiles still have it when it comes to performant UIs that delight the user. Ultimately though, your app or web site is really only as good as your designers and coders.
Pro Simpler to develop
The thing about developing for devices (particularly iOS) is that there are far less variations in hardware and software than the Web. No trying to handle all the variations of IE, Firefox, Chrome, Safari etc on Windows, Linux and OS X. Same goes for the APIs, no where near as many issues with things working or not working and it's rare in a mobile to have to do any sort of if-this-platform-or-that-platform style coding which I often saw when doing web work.
Con Development cost
Again depending on what you are doing, you may need developer memberships, device purchases, etc. Of Course web develop can also come with it's own costs too.
Then there are the development costs. On average, a mobile development takes longer than a web development. Although it's all going to come down to the skills and quality of the developers you have. Just because something is done fast, doesn't mean it's a good basis for a company. I've see companies start up based on a few weeks work and a couple of years later be in dire trouble because they kept trying to patch a hacked together product rather than writing a solid one.
Con Uncontrolled software updates
It is posible to code your app to ensure users download the latest, but generally speaking your dealing with hundreds of thousands of installs which you cannot control. So if you have backend servers as part of your application, you'll need to have a strategy for handling different versions of your app.
