Rack::SimpleUserAgent is Rack::Request extension which detects user-agent from user-agent string. No complicated logic for the detection, it simply(stupidly) checks if user-agent includes particular string or not.

Available Detection Methods
request ─ from_smartdevice? │ ├─ from_ios? │ ├─ from_android? │ └─ from_windows_phone? │ ├ from_smartphone? │ ├─ from_android_mobile? │ ├─ from_iphone? │ ├─ from_ipod? │ └─ from_windows_phone? │ ├ from_tablet? │ ├─ from_ipad? │ └─ from_android_tablet? │ └ from_googlebot? ├─ from_googlebot_news? ├─ from_googlebot_images? └─ from_googlebot_video?
rack-simple_user_agent automatically makes all detection methods available.
Action Pack Variants Usage
These methods are useful when you use the Rails' Action Pack Variants (as of Rails4.1).
class ApplicationController < ActionController::Base before_action :set_request_variant def set_request_variant request.variant = :smartphone if request.from_smartphone? end end
Then, you can use two types of view. For example:
require "sinatra" require "rack/simple_user_agent" configure do use Rack::SimpleUserAgent end get "/" do if request.from_smartphone? "Hello World from smartphone" elsif request.from_tablet? "Hello World from tablet" else "Hello World" end end
