I want to build a timesheet recording platforms for all the 30 interns at my internship. A simple platform where the interns have to come in the Cyber Security Center to do their hours and log in electronically and log out using their phones or laptops with GPS location. So that could only do that if they are at the physical location of the internship. Else their hours would not be counted.The biggest catch of the century:- There is no budget availableI searched online thereu2019s free programs but offer only upto 2u20133 people else youu2019d have to pay for the program.Please advise something easy to build this setup as I donu2019t have any experience in coding. I know how to build website using readymade tools.
