Lesson 4

WhatsApp is one if not the easiest app to use of all. Its simplicity allows the user to chat with friends and even form groups chats to chat with several friends at the same time.

Facebook is an app that is easy to use, but however it is not a easy as WhatsApp. Facebook's Messenger has way to many menus and different ways of using which make it a very useful app but not as easy to use as WhatsApp.

Snapchat is a very fun app to use, but with each update, it keeps getting more difficult to use, since each time they are adding new things to the app, which only complicates more the use of it.

Clash Royale as most games is very intuitive, but as you progress through the game, it obviously gets more difficult. It is one of the most simple strategy games, but because it is a so simple game, everybody knows how to play it well and everybody becomes a very good player.

Lesson 7

I could incorporate the accelerometer, Bluetooth, camera and touch screen in the OM Arcade app since all of these features can be used on a gaming level.

Lesson 9 Activity

Lesson 10

The principles that will be important for my app would be the clarity, the user interface (UI), and depth. The clarity is vital in an app development so the user experience is simplified by making the text legible. The UI is the most important principle since it is the basis in the app's functionality which will help improve the user's experience at the moment of using the app. Depth will help detail certain elements of the app by using visual layers and motion to show relationships between different elements in the app.

Lesson 11

This icon seems very appealing since it has very vivid colors and the little ghost is something very original which makes the user be curious about the app and want to download it.
The simplicity of Lucky 21 made me engage immediately since it is a very self explanatory game and vey easy to win.
