 ## Compatibility
 
-For the sake of simplicity this example works Anroid only. However, Xyfi does work on iOS with [gyroscope normalization](https://www.npmjs.com/package/gyronorm).

 In the end we decided to go with a Wi-Fi router and captive portal technology. Most smartphone users know how to connect to Wi-Fi, so there was plenty of familiarity there. We also loved the perceived sorcery of the captive portal popping up immediately.
 
-The great thing about captive portal technology is that it’s supported by all but the very oldest of smartphone/OS combinations.. Also, since a captive portal is essentially a web page, we can get the UI done with classic web development technologies.

 There are many ways to configure a captive portal. For example, [nodogsplash](https://wiki.openwrt.org/doc/howto/wireless.hotspot.nodogsplash), which works with the custom firmware, [OpenWRT](https://openwrt.org). Or the firmware [DD-WRT](https://www.dd-wrt.com) has [its own set of captive portal solutions](https://www.dd-wrt.com/wiki/index.php/Captive_Portal) as well.
