My team has 8 people, we work remotely most of the time, we have to track our projects closely on daily basis.

Our team exists based on the university funding, so we cannot afford some high-end solutions like Asana or Omnifocus or Wrike.

We have some people who are NOT tech savvy AT ALL, which means we need to find a solution that is easy to use without a steep learning curve.

We don't need Gantt Chart, task dependency or timer. We just need a good tool to collaborate with each other.

Any recommendations?
