Web: We've often covered collaboration tools for small groups and teams. Groupiful is a new webapp that's potentially useful for families trying to organise group activities and small startup teams looking to organise work.
Groupiful offers a clean, open interface that gives you a quick view of the work and activities you have to tackle in the centre, your upcoming events and recently uploaded or accessed files on the right, and your latest notes and personal to-dos on the left. You can create different "groups" to keep your personal life separate from your business one, or to distinguish specific projects. That way the family holiday you're working on doesn't get in the way of the bedroom remodel you're trying to manage.
If you have friends or family members working on the same event or project with you, you'll see the things they do and you can comment on them and star them. By default, your dashboard shows you all of your groups and all activities — click on any group to see only the relevant updates for that project.
Groupiful is free for anyone who needs to join or create up to 10 groups with up to 10 users each, which should be more than enough for most people. If you need more users or more storage space, premium plans are available.
Groupiful does a good job of expanding from a traditional to-do list without overwhelming you with enterprise-level features. If you're on a small team and need to collaborate, or you just want to bring a little order to your household or community group, it's definitely worth a look.
