In usual fashion, Microsoft acquired Wunderlist in 2015 and has decided to sunset Wunderlist for the successor To-Do. (http://www.zdnet.com/article/microsofts-wunderlist-successor-to-do-hits-public-preview/)
Unfortunately To-Do requires a Microsoft Office subscription so it no longer works for me. What are some alternatives for Wunderlist users?
On another note, it's a bit sad that Microsoft acquired two of my favorite productivity apps: Wunderlist & Sunrise and has sunsetted both. I really miss Sunrise Meet.
