Free - no ads - open source. Companion for the Chrome extension "Plus for Trello"
http://www.plusfortrello.com
This is a much-lighter version of Trello meant for users of "Plus for Trello", however its also good as a light way to view boards, lists and cards (title and description only), using less memory than the official Trello app.
If you use Plus for Trello:
** It is not a good idea to start trying Plus with this app.
** Use the Chrome extension first.
This app can also run from https://app.plusfortrello.com from any phone or browser, or as a Trello power-up.
