Coding Apps for Preschoolers, Teens and Grown-ups 

Known to all, programming skills lead to dozens of lucrative careers in technology. And, with the advent of technology, code learning is now accessible and more effortless.

As a result, the number of people who want to build a career that requires coding skills is growing fast. Alike learning any second language, encoding requires regular practice to master. However, it is not easy for today's students to get the time or access to computers to practice, so that is why mobile devices have come in handy. Students can simply download coding applications onto their mobile devices and start learning the art of coding right away.

This article talks about the best coding applications for students who want to learn to code across different age groups.

Coding Apps for Preschoolers

GoldieBlox: Adventures to coding

Available at zero cost, the "GoldieBlox: Adventures in Coding" teaches the fundamental concepts of coding in a story-based adventure where kids code a solution to deliver cupcakes all over town. Designed for kids' 4years and up, the app has various puzzles that increase in complexity as users' level up. It is packed with mini-games, stickers and allows kids to code their puzzles.

Goldieblox is based on a group of friends who marked a "birthday" on the calendar but did not know who that is. They resolve the issue in GOLDIEBLOX: ADVENTURES IN CODING - THE ROCKET CUPCAKE CO. making cupcakes for everyone and delivering them to town using rocket-propelled skateboarding until they find the party. Additionally, children play mini-games to collect ingredients and make cupcakes and program paths using visual code blocks. Each level adds to the adventure, and children can watch videos or customize coding puzzles.

Participating in a diverse and curious group of friends shows how excellent coding and engineering can be in an adventure based on history that is likely to attract more girls. This code-learning app is pretty run-of-the-mill as far as visual coding games go. Here learners can replay to fix mistakes or get help from Ruby Rail's notes (a character who is a nice nod to MIT's Ruby on Rails programming language), but more specific hints about various obstacles would help kids through sticky frustration. The mini-games develop spatial reasoning and connect with the theme of history. However, the sandbox and Goldie TV stand out, inspiring creativity and thoughtful design without restrictive stereotypes.

Compatible with:iOS.

Compatible with: iOSAndroid and Web.



Hopster is an animal-themed pre-coding logic game that helps kids learn the fundamentals of coding. Here, children are presented with a series of logical problems to solve, getting different animals to where they need to be. It is an educational puzzle game in which kids guide the animals to their homes or their parents. This app teaches basic concepts, using step-by-step instructions (an algorithm) and grouping repetitive instructions into a function. It simply begins with a bear, a void space and a cave. Children have two paths: horizontally and vertically. They have to choose and place the correct route to lead the bear into the cave. Eventually, the pathway puzzle pieces become arrows. However, when it comes to the most advanced stages, the kids no longer set the arrows directly on the animal's path but instead put the "commands" in a series of blocks at the bottom of the screen. Puzzles are divided into two levels: Each level has seven animals, and each animal has five jigsaw puzzles. When children complete a puzzle, they get a sticker for this animal's page in a free play area sticker book. The app is available free of charge but charges $1.99 for in-app purchases to unlock challenges.

Compatible with: iOS.

Once these have been mastered, students are free to create their own coding programming stories.

Further, Hopscotch provides excellent, quirky graphics that look like old school arcade games, which can be accessed by simply signing in with an account and email address. The Home screen of the app shows two options, Make or Play. The Make option lets you begin a project. Parents and kids will find that very overwhelming, and we suggest you follow one of the projects with the in-app video to get used to the controls. It has got four of them. At the same time, the play option seems to be locked in a different screen version of the application. However, there are many options here and several different categories.

Tynker: Fun Coding for Kids


Designed especially for kids, Tynker is a programming language app with over 20 million kids as their learners.

Whether they want to build an app or make their game, the easy drag-and-drop visual blocks make it really simple to do. Precisely, Tynker is part of an expanding category of LEGO-like programming tools, where children assemble blocks of code to create operational computer programs. The approach, made popular in education circles through MIT's free Scratch platform, encourages learning through exploration rather than memorization of arcane programming formats and formulas.   

Players encounter new programming concepts step by step as they try to solve programming mini-puzzles. A typical puzzle provides them with a few simple code blocks such as jumping, walking and repetition.

When the blocks are assembled in the correct sequence, a colourful cartoon character ambles across the screen, hopping onto the obstacles and reaching a reward on the other side. A variety of challenges take the player into outer space, solving puzzles on locked doors using programming code, and even a set of levels where programs cause a small robot to draw shapes on the screen. Feedback after each level rewards the stars for correct responses and provides guidance when the program is unable to resolve the assigned task.
