Project management software

One of my biggest frustrations with the management softwares is their cost. Some of them provide free versions, like Trello, but they have limited features, which makes it quite bothersome. Recently found with that's free with good functions and has a good mobile app to support them, Quire, but I'm still searching for more softwares to try out.

The biggest problem - high cost for task management software. But I found really good and cost-effective one - TMetric tmetric.com/.

I highlighted these features for myself:

• Task management;
• Billing and Invoicing;
• Timesheet Management;
• Offline Time Tracking;
• Mobile app Time Tracking;
• Overtime Calculation.
