It's got a reactive web design that is mobile-friendly and desktop-friendly It was easy to tailor to operations management for commercial real estate. It can run on a very lightweight server infrastructure.
It's completely open source with a quite polished interface. There's enough options here to run a full company (variable rates per company). You still need invoicing software (say Invoice Ninja) to finish the billing, but Kimai can produce excellent billable hours reports.
It has downloads that are not for windows. It is unclear how someone who is not a programmer can use it. Most likely we need to wait for someone to offer it for free for non-programmers.
A good tech could figure this out pretty quickly but you're right - it's not plug n play in Windows although it is possible to get this running.
You could run it in a VM (HyperV) or with Docker (which might be easier). Windows has HyperV included and Docker Desktop is free but it does require a bit of tech knowledge to get these set up.

Open software, web-hosted, could be used in a simply way.
Kimai tries to be both straightforward and complex - something quite rarely achieved in programs. One has to take some time to trial-and-error (documentation is rather concise) to figure out how some elements of the interface works, but than it is seems to be just great! Unfortunately, the mobile interface has to be installed separately, although mobile devices are quite wide-spreed today (and will more).
In nutshell: nice, one-task, useful software.
