As wanted to programing on iPhone, I installed a application called Buffer Editor which costed me ¥60!! After a while using, I just want to say: what the fuck of this ¥60 shit!!!

• the shit UI which costed ¥30 unless the logo icon
• the shit features' usage costed ¥28 which make a coder like a foolish
• the left ¥2 given the author, go back home and wash your mind for 10 years

At last I have to install Textastic instead which cost ¥68. Both ¥60s, why your distance so much long? Even though Textast is less of features, the UI and the operation logic is like silk. 

For all application developers: make your production worth for users, don't lose your face in public.
