Great idea, I bought one when my DGT Cube broke down but sadly it doesn't live up to its advertising hype. To begin with it cost over 50% more than the DGT Cube, which sadly is now obsolete. Opening it to change batteries involves damaging the casing slightly. It should pause if you tap it, but that rarely works and I have to pause it in the associated app. However, it randomly pauses itself and keeps losing time over a work day. The manufacturer did eventually replace it, but the replacement loses time as well. This makes it useless to me as I need to charge my time to various Companies and I can't trust the device to be acurate.
