The world’s largest online shopping mall can fit in the palm of your hand. Check out three of the ways Amazon helps you find and save items, compare prices and place orders–all without ever booting up your computer.

1. Amazon Remembers

Part visual sticky note, part search engine, Amazon Remembers allows you to snap and save a photo of items you’d like to remember–whether it’s your neighbor’s enviable set of lawn flamingos, or office supplies that you keep forgetting to order. Amazon takes the functionality one step further by scanning your photo and searching the vast reaches of the Amazon inventory for something similar.

2. Scan It

For quick price comparisons on the go, not much beats Amazon’s mobile “Scan It” feature. All you have to do is open the feature, line up the barcode and wait for your results.

3. Mobile 1-Click Ordering

Simply enable Mobile 1-Click Ordering in your Amazon app settings, and you’re well on your way to being the fastest shopper in the West. 1-Click Ordering allows you to skip those bothersome checkout and order confirmation steps. Just beware that, in exchange for lightning-fast ordering, you’re giving up the chance to alter shipping methods or add any gift options.
