Bloo is soo simple and easy to use, everything is straightforward and up to point. You can get up and running immediately after the on-boarding, no tutorial/guides needed (For ones who need it, they have good documentation as well).
Usually, project management tools have lot of options to achieve a hundred different things which makes managing the "project management tool" a task, but never got that feeling with Bloo. Sadly, I wasted a lot of time and money hopping from one PM tool to another and never knew about this tool. Now I am set! Bloo is underrated!

However, Bloo doesn't sacrifice functionality with its simplicity. Some of the features I love are,

🌮Ability to give clients short-term access to projects
🌮Calendar view of all activities.
🌮Automation rules for tasks
🌮Custom fields
🌮CSV file import
🌮Highly Customizable notifications
🌮Chat discussion within the projects

Some other +ves
🌮Neat UI/UX
🌮Cool mobile app
🌮Unlimited Storage

They deploy updates every now and then, and their roadmap is also good.
Support team is fast to respond and they are very helpful :) A friendly bunch ..

I was not able to find any negatives with this.. (maybe because I am blinded to finding cons with this one XD) Most of the features I thought was missing in Bloo is already on the roadmap.. I want them to stay for the long haul.

As for the pricing, it is very reasonable with Tier 5 giving Unlimited users. A thing to note is you can create one company for purchasing one set of codes. For a second company, you need another set.
