15 App Ideas to Build and Level Up your Coding Skills

1. Countdown Timer

Tier: 1-Beginner We all have important events we look forward to in life, birthdays, anniversaries, and holidays to name a few. Wouldn’t it be nice to have an app that counts down the months, days, hours, minutes, and seconds to an event? Countdown Timer is just that app! The objective of Countdown Timer is to provide a continuously decrementing display of the he months, days, hours, minutes, and seconds to a user entered event.

2. FlipImage

Tier: 1-Beginner It’s important for Web Developers to understand the basics of manipulating images since rich web applications rely on images to add value to the user interface and user experience (UI/UX). FlipImage explores one aspect of image manipulation — image rotation. This app displays a square pane containing a single image presented in a 2x2 matrix. Using a set of up, down, left, and right arrows adjacent to each of the images the user may flip them vertically or horizontally. You must only use native HTML, CSS, and Javascript to implement this app. Image packages and libraries are not allowed.
