Do these label printers work with iPhone and Android?

The Bluetooth thermal models (Phomemo 241BT, Nelko, JADENS, Nelko P21, SUPVAN E11) all advertise iOS and Android apps. The Rollo USB model does not — it's wired to a Windows or Mac computer. The Brother QL-820NWB supports Wi-Fi, Ethernet, Bluetooth, and USB, which is part of why it costs what it does.
