In the current state Cowry is quite similar to those, except we will have our mobile apps released soon(as far as I know they don't have that), so you will be able to manage your rigs on the go.
What will make us quite different in a few months is the option to put your GPUs up on a marketplace, where AI/ML researchers can rent it for a higher value than you would earn by mining coins. Our architecture won't require any extra hardware(extra RAM, high-end CPU, extra SSD storage, etc) in a rig, since the only thing the researchers will rent is the GPU.
Another cool feature we are working on is an open hardware rig resetter, you can buy the hardware part and just put our firmware on it and you can manage it from your Cowry account.
