For an "app" to have any hope of being downloaded it has to have a fun or handy informational bent. If it obviously is designed just for marketing your business only your closest relatives and bill collectors will bother with it.
This particular app looks like a standard mobile website template, so maybe it would be better if you just use it as a mobile website. When people visit your website using their mobile device it can be placed to come up automatically and will be much easier to read on a tiny screen than your standard site, and this way will be valuable without being seen as storage sapping phone clutter.
Keep the "find us" feature unless you don't want anyone to find your physical address using their phone.
