Also curious how Hyperlogs compares to Toggl? I use Toggl for my DevOps consulting company and it works well.
That all said, you should give it a shot. Sign up and try it, it is free for one user.
I disagree that it's more streamlined though. toggl's killer feature is the ability to switch between tasks with 1 click as I'm performing the work. For mine this is the big distinction between an after-the-fact timesheet data entry app like hyperlogs and an actual time-tracking app like toggl.
The majority of my interaction with toggl is via the desktop app and chrome plugin, any competitor without these integrations is a non-starter.
