+==========
+
+Awesome Timesheet is a mobile app that helps me to instantly record 
+any time spent on projects in just a click. It's so effortless.
+
+Regardless of the device, the timesheet app is just one click away. 
+Look at the chrome plugin. No need to sign in, just click and start. 
+It's smooth. It works offline too and is automatically synchronized 
+with my Odoo account.
+
+Plus, I get individual statistics via the mobile and chrome plugin. 
+I can go further in the analysis in my Odoo account. I receive reports 
+of timesheets per user, drill-down per project, and much more. 
+
+Awesome Timesheet is fully integrated with Odoo invoicing, the customer 
+billing is done automatically. But also with Odoo projects. It's time-saving!
+
+Download awesome timesheet now and gain in productivity.
