Startup Idea: Construction worker timesheet mobile app

Startup idea to develop a mobile app that allows construction workers to record their own work times, eliminating the need for them to rely on their managers' judgement, and reducing potential conflicts.

i work in construction and feel like my boss often isnt recording my work times correctly. if an app could be made that i could clock in and out of on my phone was available, that would really help. he also likes to drink a lot and i miss out on work a lot because of that and it makes it hard for him to accurately record my times. if i could do it from my phone it would eliminate a lot of arguing at my job. no, i just rely on my boss.
