I like the fact that it is a completely private tool. I use it to communicate with my project partners. It is very convenient since I can use it to assign taks for a project, share a folder full of files, and not just a unique file. If you use Dropbox or Google Drive, you cen replace the native file manager by a Dropbox or Google Drive Widget.
I do not need to use a task manager app with my Whaller teams thanks to the native task kanban but it is not as powerfull as Trello even if it meets my needs.
The customer support is great. It is easy to get help from their founders and engineers and they help you implement Whaller if necessary.
Overall, Whaller is a very nice tool for teams. It can be a social network for you company, a file management tool, a project management tool and even a simplistic version of Sharepoint.
I think the mobile app is one thing that needs to be improved. It is something that is very common with apps that offer a lot of features: they can’t all fit in a mobile format. They said they are improving the mobile map so it will be ok soon. I do not even use the app thatmuch but I had to fill that space.
It is a great tool for education and work because it makes your productivity increase. However, to make sure it is really useful, you’ll need to convince, and even force your team to use it. There will always be people that will not fancy using a tool they don’t know and you need to convince them. It is also true for every collaboration tool.
I was using Flock before Whaller. Flock is nice but I needed several oher features and adding a common Dropbox/Box, Trello/Asana, calendar integration that will satisfy everyone in my team would have been complicated. Whaller offers all these features even if they are not as powerfull. It is enough for me and my team.
