I just came across two similar but different apps that could be of great help to solopreneurs, freelancers, startups and small businesses. Both apps are great for project management and have additional useful features. These offerings come from our neighboring state of Georgia created by 23rd & Walnut.

I took some time to explore the demo versions of both versions mentioned below. Each version has an intuitive interface and a solid accompanying feature set.

Solo - Cost - $0 - As you may have guessed is positioned for solopreneurs and freelancers. The bonus with this version is that the program is absolutely free. This app is more than just project management. It also offers, task management, file management, a project calendar, a task timer, an activity stream, a global search, client pages and HTML emails.

Duet - Cost - $49 - This version focuses on multiple users and the additional features they need. This version has, file management, task management, a visual invoice builder, integrated team messaging, payments via PayPal or Stripe, reporting, an activity stream and project calendar.

My suggestion is to try out both versions via their online demos and really think about the feature set you and your venture need. I think you will be really impressed with the quality of the apps. I was, and that is why I've shared them with you.
