IoT for connecting

Everyone and Everything



Simblee is IoT for connecting Everyone and Everything (IoT4EE).

It incorporates Mobile, Bluetooth® Smart, Mesh, Cloud and other forms of wireless connectivity.

Simblee is high-quality, cutting-edge and performance focused.

Using the Simblee mobile browser on a phone or tablet, anyone can interact with Simblee enabled devices instantly without needing to download additional apps for each device.

In just hours you can create functional IoT applications using the Simblee development environment.

Developers can start developing mobile apps without having to first learn Xcode or Android SDKs.
