Ora is, at its core, a task manager, but it's so much more. You can use it to project plan and share ideas.
If you look at the Ora website (link below) you'll see how you can add "clients" (parent) to your projects and they will be able to see what you're working on. This might be a nice way to share information with parents as well as keep yourself or your teams organized.
Ora is free to use with paid subscriptions to gain more features.
There is a deal going on through AppSumo (link below) where you can get a lifetime subscription for a 1-time price of $59.
