I am an entreprenuer, freelance designer, and business consultant. I rely on technology to keep in touch with teams/clients while working any and all of my projects. Like a lot of poeple I found trello when looking for free alternatives to similar apps. I figured it would fit my needs, but didn't expect much. Trello by far is better than I expected. Even witout upgrading to any of the paid options, I find Trello is way more useful than I ever thought it would be. It is really easy to navigate and understand and within a day of setting up my account, I recieved emails in my inbox with videos on how to get the most out of the app. I strongly recommend trello to anyone who needs to organize to-do lists, task, project guidelines, etc. with a team of 2 or more people.
Though I love Trello, there are a few things preventing me from rating it 5 stars:
1) Though it provides excellent push notifications to my mac, I wish that I was able to add a trello widget to notification center in MacOS. It would be a bonus if it were an iOS widget as well, but I would rather have one for mac.
2) There is no menu bar icon. Having a quick glance access in the menu bar would be AMAZING.
All in all, this app and service is great. If you need to colaborate on any projects in the near future, you need to give Trello a try.
