As answered by people managing DevFinanceTools and TimeFlip.
TimeFlip's answer:
We are building a human-friendly and educating IoT device to help individuals in managing their time and workload. Unlike pure digital time tracking apps, TimeFlip is a connected, physical device. This provides radically different UX and ensures ease of use and instant adoption. TIMEFLIP2 is an app-powered dice that makes time tracking easy and accessible to anyone, irrespective of their level of computer literacy. This tactile device sits on the user’s desk and logs time with a simple flip. The device comes in the shape of a dodecahedron with 12 sides that can be assigned to 12 different tasks or activities. At the start, a user marks his/her tasks or activities on the sides of TIMEFLIP2 and assigns them in the mobile app. The tracker is fully set to work. Now a user only needs to place TIMEFLIP2 so that the current activity is facing up and the device will log time for it. Time logs are stored in the local memory without the need of permanent connection to the app. The tracker automatically syncs with the app once the app is opened. The app pushes time logs further to AWS cloud for storage, visualization and export via our proprietary web interface.
