Isimio

Isimio is a highly configurable scheduling application on the Salesforce platform, which can interact with all of your date or time-based data. Whether you manage remote workers, support cases, projects, assets, or any number of other utilities, you can use Isimio to see a clean view of your data, and edit it with a mix of intuitive UI and smart features that are otherwise unavailable on Salesforce. In addition, you get real-time validation against any number of compliance rules you set up.

Isimio supports 1st and 3rd party plugins. For example: staffing companies can get time & attendance, work-time regulation compliance, candidate matching, and a candidate mobile app.
