Timeneye is a time tracking and time reporting web app made with usability in mind; it is extremely easy to use and to set up, so that employees will really enjoy it and project managers won't have to keep reminding them to enter their timesheet.
To achieve this, Timeneye keeps its interface essential and non-invasive, giving users the possibility to track time from the web-app, a Crome Extension or an Android native app (iOS and Windows Phone native apps are coming soon).
Timeneye gives its best when integrated with Basecamp: it is the only time tracking tool that allows Basecamp users to track time directly from there, just adding the time spent on each to-do as a comment on the to-do itself: Timeneye syncs with Basecamp and pulls these time entries, making them readily available for reports.
Timeneye can be tried for free. After the trial, there are monthly plans for each type of company (pricing depending on the number of projects used).
