# Overview Blynk offers native iOS and Android mobile apps which allow to remotely control connected devices and visualize data from them. App operates in two modes: #### **Developer Mode** The primary function of Developer Mode in the mobile app is to [build and edit the Mobile Dashboard User interface (GUI) for the given Device Template](https://docs.blynk.io/en/~/revisions/ynmC8lZ6FPocTYWigjcO/blynk.apps/constructor). Mobile Dashboard is built from Widgets - modular UI elements which can be positioned on the canvas. Every Widget serves a special function (a button, a slider, a chart, etc). Every Widget has it's own settings based on its functionality**.** #### **End-user mode** This mode is used by both the makers and the end-users. It's focused on devices, automations and notifications view and management with the help of widgets and additional screens containing specific information about data that is set/sent/received to/from Blynk.Cloud and devices. ## Home screen Home screen consists of up to 3 tabs depending on the configuration: [Devices](#devices), [Automation](https://docs.blynk.io/en/~/revisions/ynmC8lZ6FPocTYWigjcO/concepts/automations) and [Notifications](#notifications) ### **Devices** ![Devices tab](https://user-images.githubusercontent.com/72790181/119994901-b923c300-bfd5-11eb-9475-a0d1826a875b.png) This section is open by default when you open the app. All created devices will be listed here and their tiles will look according to their [template ](https://docs.blynk.io/en/~/revisions/ynmC8lZ6FPocTYWigjcO/blynk.console/templates)type.
