Simple In Out is an employee in/out board that works across multiple platforms:
As well as providing a useful visual display of who’s in and out it’s also possible to use the system for employee timekeeping, notifications when people come in/out and integration with Slack or other systems via web hooks or the API.
Simple in/out uses the employees’ phone’s operating system to detect the geographical area using cell towers or local WiFi Networks. It’s possible to use beacons to improve the accuracy. Beacons are better when you need to use Simple In Out with smaller areas (10-20 metres), moving areas or areas with poor cellular reception or no WiFi.
