Zoho Planner is a free online organizing tool. It is a space where you can write to-do lists, set reminders, make and keep notes, and upload documents and images. All of this information can be shared with friends, colleagues, family, or even the general public. Zoho Planner shares some of the same features of other online calendar applications such as Google Calendar < http://www.google.com/calendar/ > or 30 Boxes < http://www.30boxes.com >, where activities can be written on an online calendar. What makes Zoho Planner different is that it emphasizes the tasks and activities that you need to complete, rather than simply being an online version of an agenda. For people who like to make lists of what they need to complete, Zoho Planner can be a valuable tool, especially for people who like to contextualize their lists with notes, uploaded documents or images, and tags, which makes Zoho's product more robust than other online to-do lists. Its free price also make it more attractive than a similar product from Backpack whose free plan limits the number of people you can collaborate with to two, the number of pages you can create to five, and does not allow for items any files to be uploaded.
