Looking for alternative to Trello? Zenkit is the answer. It's a collaborative project management software with easy, sleek interface and relatively fast for old devices. Zenkit features calendars, to-do list and necessary things you need to create a progress with your project. Even offering the same service, Zenkit allows you to import from Trello boards just in case you prefer Zenkit over Trello. But what makes Zenkit is different is that, this software comes with mind map view of the board.
As claimed from their website, one of striking difference from Trello and Zenkit is the privacy. So, if you are privacy driven user, Zenkit may offers alternative option for you. They are a company based in Germany and follows the strict GDPR data processing. It also follows SSL protected data transfer which means the data is securely transferred using encryption protocol. This benefit is a plus poin for Zenkit compared to Trello.
