I'd like to share my thoughts and opinion with other users about my prefered typing keyboards to input text. I've been using Fleksy Keyboard since the first day of purchase from the AppStore on fall 2012. I love how fast and acurate I use to type on Fleksy, it was a new typing experience for me. When the iPhone 5S came out this fall things have been changed, the processor on the iPhone 5S has made my typing experience better and much faster than previous iPhones using the iOS keyboard. I applied the same typing tecneeq I learned from Fleksy and had good results I can say. One feature I really love about Fleksy is browsing through the list of word suggestions, while in iOS keyboard I couldn't brows the list of available suggestions. Another reason I don't use Fleksy in my iPhone 5S because I couldn't change the default iOS input keyboard to Fleksy and type in using other languages such as Arabic. The iOS keyboard in my opinion does a great job for me.
I am very pleased to hear other users ideas and know what do they like the most.
