KidsScript is a full-fledged programming language app for kids and teens. Through visual block programming that is compatible with JavaScript, we have made it possible for even young children to use JavaScript. You can get used to programming while having fun creating various shapes and games. And from version 2.0, it supports hobby electronic work! You can program the currently popular microcontroller called ESP32 using KidsScript's code. And you can learn how to use various electronic parts, drive your own robot car, and do anything with your creativity! The app has a wide variety of samples and detailed tutorials, so please give it a try! [App's main specifications] ●Simple app No login or account creation is required. And this app doesn't contain ads. And it doesn't collect any personal information, so you can enjoy it casually. ●JavaScript compatible language The language of this app "KidsScript" is compatible with JavaScript 1.5 and allows JavaScript to be manipulated as visual blocks. Therefore, you can naturally get used to JavaScript through coding with this app. ●Appropriate age This app is mainly intended for children aged 13 and over. But even children as young as 9 years old can touch and play with the samples together with an adult. [ 9 - 12 years old ] - can play samples with adults - can create elementary programs with adults [ 13 - 15 years old ] - can do tutorials by oneself - can create elementary programs by oneself [ 16 - 17 years old ] - can understand all samples and tutorials - can create programs freely by oneself ●Supports Bluetooth communication By connecting two KidsScript apps via Bluetooth, you can create codes that communicate in real time. Therefore, you can also create online battle games! ●Supports ESP32 Targets ESP32-DevKitC-32E. By installing "KidsScript firmware" on the ESP32 side, KidsScript and ESP32 will be able to communicate via Bluetooth in real time, making it possible to code ESP32 with KidsScript. KidsScript firmware for ESP32 is distributed on the KidsScript official website. [URL] https://www.kidsscript.net/ ●More than 150 code samples included with this app It's fun just to look at various samples and play! ●More than 30 tutorials included with this app The app comes with an "interactive tutorial" that will teach you how to do it, so anyone can get started easily. Even if you have no programming experience, it's okay!

Verdict
The clearest difference is in-app purchases: KidsScript at none against techSampler's 1. KidsScript also leads on update cadence (every 5 weeks vs every 4 months). techSampler's advantage is iOS requirement (7.0 vs 12.0). On price, ads and device support there is nothing between them.
