Wunderlist

I have been using Wunderlist for several years. It is my favourite apps as it is free, supports synchronization across devices, supports Android and Chrome extension.

Unluckily, it is going to shut down in May 2020, as it is superseded by Microsoft To Do.

Though Microsoft To Do supports Android and web, it doesn’t support Chrome extension.

There is a great difference of using webpage and a browser extension. The former is when visiting the page, the browser will download the HTML, CSS, and JS then run the web app; the latter is to download the HTML, CSS, and JS as an extension, and run the extension to use the RESTful (or JSON) API directly, without re-downloading the page as the former. This also means, the latter is faster than the former.

Microsoft To Do allows import all the data from Wunderlist. But if import twice, the data will be duplicated. Whatever it is, Wunderlist is definitely going to be replaced.
