Life as an entrepreneur might seem glamorous to the outside observer: building something from the ground up, attending networking events, being your own boss, and setting your own hours. As any entrepreneur knows, however, the early years are anything but glamorous. They’re full of sleepless nights, crushing insecurity, and too many cups of coffee. Building a business is challenging and time-consuming work, and it’s often very isolating. Most entrepreneurs start out working by themselves, and have to do everything, from the bookkeeping to the marketing. No one is good at everything, and tough tasks can sometimes be overwhelming or waste precious time. The good news? There are so many great online tools available to entrepreneurs these days—tools that can help with time management and make getting enough sleep a little bit easier.

If you’re an entrepreneur, check out these 5 free time management tools to help you stay sane!

1. Toggl

If you’re like most people, you waste a lot more time than you think you do. Unfortunately, that’s difficult to quantify unless you have the cold, hard data in front of you. Toggl can give you that. Toggl is a time-management tool with a very simple premise: tracking your tasks. It’s super easy to use, and you can track individual tasks with the click of a button, pause and come back to projects, and see how long you’ve worked on each one throughout the day. Different features allow you to tag different projects and clients, and you’ll get a weekly summary of your tracked tasks every week. It’s a must for anyone who gets motivated by the ticking clock. Need evidence you’re working too much? Ask Toggl!

2. Trello

Trello is an extremely powerful project management system, thanks to its overall simplicity. You can create “cards” for different projects, and organize them in lists. These lists are contained on boards, giving you the flexibility to separate and organize all your tasks. You can drag and drop these cards to different lists, set due dates, add attachments and notes, and assign other Trello members to specific cards. This is a great tool for entrepreneurs who have several projects in the works, or who work with multiple freelancers. Everything can be tracked in one place, and the software can be integrated with other tools!
