It works fine for my use-case which is basically just tracking my work-time for the employer I’m working at, so I don’t really use the freelancing options like invoicing.
Had some problems with the docker container, because they did some breaking changes, but overall it works for me.
It also supports SAML so I can use it with Keycloak and there is an app for the iPhone, which I’m using that works nicely with it.
