I use both Evernote and Yinxiang Biji China (印象笔记) to take different notes and share to different people. I've installed: Evernote desktop for my ThinkPad PC with Windows 8.1 Evernote desktop for my Surface Pro with Windows 8.1 Evernote Touch for my Surface Pro with Windows 8.1 Evernote for my Lumia 920 Windows Phone (Win8) I've figured out a way to switch account on my desktop version - I just need to set my system locale to Chinese Simplified (China), without changing any other settings. How can I switch between Evernote and Yinxiang Biji (印象笔记) on my Windows Phone and Surface (Evernote Touch) as easy as the desktop version? For my Lumia phone, the only way I've figured out is to set my region to China. That stinks. It means I need to restart my phone. Plus, I am living in US, it is not convenient at all to use a cell phone with region setting in China. For Evernote Touch for my Surface... Sorry, I've figured out no way... Thanks in advance for any suggestions from you guys! It will help me a lot if I can easily switch account on my phone and Surface (Touch).
