What software is better for construction workers?

I think construction workers can use fishing nets to pick up jobs. First of all, it is a mobile phone software, which can be installed as long as it is a smart phone, which is very convenient. Secondly, the software specially designed for construction workers is professional and formal, and the big platform is safer. Finally, his ability to find a job covers all kinds of job recruitment information on construction sites all over the country, and he can find any job.
