Great for time tracking, works the best with Chrome extension plus Android app.
I didn't use all the features available but for my needs it worked out perfectly. Their customer service is very responsive and polite when it comes to inquiries made.
With the TrackingTime Extension for Chrome, Firefox, Safari, and Edge enhance SupportPal with time tracking. Get automatic timesheets and enjoy TrackingTime’s in-depth analytics.
