Update - Now Available Open Source - I have stopped further development of this product.  I hope that a talented .Net developer can take it to the next level.

I'm releasing a beta build of a time entry application for Freshbooks.  I created it to help make sure make entering my billable time easy when I'm on the go...and I wanted to learn a little more about mobile device development since I typically focus on Microsoft infrastructure products such as Hyper-V or Exchange 2007.

• (0.5) Submits time entry on the go including Project, Task, Date, Hours, and Notes

Use

• Press Get Freshbooks Data to fetch tasks and projects and tasks (also invoices, clients, payments, and . 
• Select the Project and the task you are working on.
  Note - You must manually remember what projects are associated with each task.  There may be errors if the task is not associated with the project.
• Enter the select the hours to be logged up to a maximum of 12 per entry.

FAQ

• Error 401 - Your API token or URL is set incorrectly...most likely your API token
• Connection Timeout.  Make sure you have good reception or have internet access.  If your not connected to the internet, it may timeout the first time, just retry.

Known Issues:

• Only works with one user, the administrator.  Other users/employees cannot submit time. This is a limitation of the Freshbooks API.
• Only supports time entries for Projects/Tasks, no invoice support in the short term.
• Random errors when getting project info or submitting time.  You should be able to just retry by clicking the button again.
• Tasks cannot be filtered based on project selected due to the current API of Freshbooks...or a heavy performance loss.
