This isn’t an app but I had to add this because your grammar will set you a part from every other writer on the Internet. People will take your business seriously. You could lose a job due to mistakes in your writings. Grammarly is a simple Chrome extension that critiques your writing and spelling in whatever web document that you are working on. This way you can see what mistakes you are making and quickly fit them.
Even if you only download one of these apps, I promise you you’re freelance career will be upgraded.
