Despite the overwhelming evidence that shows native apps are more popular than the mobile web, we should remind ourselves that native apps are not without their flaws. Here’s noted usability expert Jakob Nielsen on the problem with native apps:
Apps have the obvious downside of requiring more development resources, especially to be truly optimized for each device. If a company doesn’t have enough resources to do this right, it’s better to have a nice mobile site than a lame app.
A second downside of apps is that users have to install them. Our testing shows poor findability and usability in Apple’s Application Store, and many users won’t even bother downloading something at all for intermittent use. So ask yourself whether you’re really offering something within the hardcore mobile center of need: time-sensitive and/or location dependent, and whether your offer is truly compelling in this crowded space. Most companies are never going to make it big in mobile. In some cases all they need is to make their main website somewhat mobile-friendly. Many others should deliver a dedicated mobile site but not bother with apps.
