HeapNote is a custom-fit online notebook. It lets
you manage your ideas, bookmarks, todo lists, expenses or anything
else that is important to you with an extremely flexible,
powerful and easy to use interface.
All your data is securely stored, available 24
hours a day, thanks to Google App Engine.
Each note can have multiple fields (either text or
numeric). Numeric fields are automatically summed up. You
can use it e.g. for simple tracking your expences.
To categorize your notes you can also use labels
which are organized into a tree. You can easily mark notes with
labels using drag & drop.
