&gt; There are plenty of apps that are guilty of this as well. Instagram comes immediately to mind.<p>For native apps it&#x27;s a design choice.  For whatever reason (good or bad) they don&#x27;t want you to zoom in.<p>For websites instead, pinch to zoom exists for a design deficency, mostly for web pages not optimized for small sized screen. Responsive web design is helping but the gap is not filled yet. Hopefully it&#x27;s just a matter of time and we&#x27;ll experience beautiful mobile websites.<p>For all other needs, there is OS assistive zoom.
