Hey Cody,
Currently you can review products from the desktop version of our site, not yet on mobile — but that is something we plan on updating in the near future. The review form is located at the bottom right of every product page.
Elite points can be spent by adding items to your cart, then viewing the cart page at:
https://store.theory11.com/cart — As long as you're logged in, and have elite points, you should be able to convert as many as you like into a cash coupon to use during checkout by dragging the slider left-to-right.
You can learn more about the elite program here:

And of course, always happy to answer any questions you may have
