Altro Smart Lock is a Bluetooth & Wi-Fi enabled smart lock. Its unique design makes it unpickable and tamper-proof. Security means not just feeling like all is well, but knowing it is. We have noticed that current dead-bolts are not secure enough and smart-locks are just adding convenience while they do not add to existing security. So we set out to build our own. Altro makes your Smartphone your new smart key—and more. Lock and unlock your door, create virtual keys for guests, and keep track of who comes and goes, all from your iOS or Android smartphone.
