Latch has been forced upon me by the new owners of the apartment complex where I live. I miss my physical key. it doesn't require electricity to function properly, it doesn't notify anyone when I come and go, and, it doesn't drain my phone battery cause it works without having to turn on GPS & Bluetooth. I see no good reasons for latch to be used in a residential setting. It only makes sense for places that need high levels of security and monitoring, like the pentagon.
