Clockify

Free version is very good, tracking of time and working time log are very easy and flixable , reports are very helpfull

Tracker has no uper limit to stop at even you forgot to stop it for days (continiously)
Not very powerfull with task tracking where there are no tastk status or team calloperation of tasks, as least in free account

The interface is nice, the reports get me what I need for invoicing. I can tag any recorded time as billable or not billable and even enter the dollar amount.
I tag entries for specific clients or types of work with various colors which helps differentiate entries.
The weekly emailed report helps me make sure my time is on point.

I didn't find the Windows desktop tool all that helpful, I just use the web interface.
It's not as streamlined to create a new project or client easily. I have to type a project name (which doesn't exist) then I can create it on the fly, but with no details such as setting the color or client. So I have to go to another part of the interface, track down this new project so I can set the client and color, etc. I wish I could set up all the details about project and client directly from the time-entry page and not have to go around the interface to finish adjusting it.

I don't really care for tracking precise start and stop times separately. Each time I have to stop and start a particular project time, it creates another entry. I prefer a generic single timer that accumulates, rather than a bunch of sub-time-entries like 10:34-10:45, 11:02-11:18, 12:50-1:42. This doesn't do much for me. I just want a single timer that says I worked 3.4 hours or whatever. But this is pretty minor thing. I can ignore all the sub-entries for the most part. But where this gets ugly is when I want to come back and enter time manually. If I need to adjust times, it's nearly impossible because I don't want to create time entries that overlap with existing entries. There is a lot of fudging numbers around so I can line up my projects.

There's so much to appreciate about Clockify, but what stands out most is its remarkable User Experience (UX). I've had the pleasure of using it across a few companies, with over 100 users involved, and the feedback has been overwhelmingly positive. Clockify's intuitive design allows for seamless navigation and operation, effectively minimizing the learning curve and enhancing productivity. The trial version, in particular, deserves commendation for its comprehensive features without any intrusive upselling, truly epitomizing value.

If there's one area where Clockify can improve, it would be a slight update to its User Interface (UI). While the current version is certainly functional and efficient, it could benefit from a few aesthetic and usability updates to better match its excellent UX. However, I want to emphasize that this is a minor tweak and doesn't drastically affect the overall satisfaction derived from using the platform.
