Development with Kotlin is often cheaper than with Java, as well as being easier to maintain during a project\u2019s development.<\/li>\n\n\n\n<li><strong>Ease of use for developers.<\/strong>  There are many additional features that are not available in Java. For example, data class, getters, and setters to reduce boilerplate (and therefore the amount of code), protection from null, and a simpler class structure.<\/li>\n\n\n\n<li><strong>Security.<\/strong> The language and its programming environment are products of one company. The error base is constantly updated and helps edit code until the program is executed.<\/li>\n<\/ul>\n\n\n\n<p>Disadvantages of Kotlin:<\/p>\n\n\n\n<ul>\n<li><strong>Slower speed compared to Java.<\/strong> Kotlin works on the JVM engine, which was developed for Java, so the compilation speed is slower.<\/li>\n\n\n\n<li><strong>Smaller community.<\/strong> Kotlin is not as popular as Java, so there isn\u2019t as large of an accumulated base of use cases and error solutions.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-lazyblock-heading lazyblock-heading-1hy4sa\"><h2 class=\"article__h\">We create mobile applications <\/h2><\/div>\n\n\n<p>Kotlin OS is often used to develop mobile apps on Android: 80% of the top downloaded apps on Google Play are developed using Kotlin. At OrbitSoft we also use this language to write mobile apps &#8211; for example, for an entertainment platform in Canada we developed a VPN-connected app for easy access across multiple countries.<\/p>\n\n\n<div class=\"wp-block-lazyblock-link-text lazyblock-link-text-HCebD\">      <aside class=\"article-aside js-article-aside_under\">\n    <div class=\"article-aside__body\">\n                            <a href=\"https:\/\/orbitsoft.com\/blog\/vpn-app-how-we-fixed-others-mistakes-and-launched-the-project\/\" class=\"article-aside__link\" rel=\"nofollow\">\n                                              <span class=\"article-aside__txt\">\n                      <span>VPN app article <\/span>\n                  <\/span>\n                        <\/a>\n        <\/div>\n<\/aside><\/div>\n\n<div class=\"wp-block-lazyblock-figure lazyblock-figure-1GxL9O\"><figure class=\"article__figure \">\n        <div class=\"article__figure-img\" >\n        <img decoding=\"async\" src=\"https:\/\/orbitsoft.com\/blog\/wp-content\/uploads\/3333.jpg\" alt=\"\">\n    <\/div>\n                <figcaption>This is the app interface on Kotlin.

Thanks to Kotlin, the functioning of the application is invisible to the user\u2019s eye. But it works, and doesn\u2019t require a large number of resources to maintain.<\/p>\n\n\n\n<p><strong>Cascade Connection makes the connection process invisible. <\/strong> The VPN allows the user\u2019s device to connect to a specific server and access the desired content. Sometimes, when connecting, errors occur, and a connection can\u2019t be established.<\/p>\n\n\n\n<p>Cascade Connection solves this problem seamlessly: if it fails to connect to one server, the application automatically connects to another. The user is blissfully unaware.<\/p>\n\n\n<div class=\"wp-block-lazyblock-figure lazyblock-figure-27f4s7\"><figure class=\"article__figure \">\n        <div class=\"article__figure-img\" >\n        <img decoding=\"async\" src=\"https:\/\/orbitsoft.com\/blog\/wp-content\/uploads\/4444.png\" alt=\"\">\n    <\/div>\n                <figcaption>Kotlin is a safe language. When executing a script, it checks variables using the null command.<\/figcaption>\n    <\/figure><\/div>\n\n\n<p><strong>Base for application logic changes.<\/strong> During the application\u2019s time in the field, the company\u2019s sign-up approach changed several times. First there were free accounts for 7 days. Then a switch was made to a completely paid scheme, where a person couldn\u2019t use the service without a subscription. Finally, a combined option appeared.<\/p>\n\n\n\n<p>By changing the application logic to Kotlin, it made everything easier to read and understand. The project is now supported by a different development team. They rarely need to ask for clarifications due to the now easy-to-read code.<\/p>\n\n\n<div class=\"wp-block-lazyblock-figure lazyblock-figure-Z1GaH4S\"><figure class=\"article__figure \">\n        <div class=\"article__figure-img\" >\n        <img decoding=\"async\" src=\"https:\/\/orbitsoft.com\/blog\/wp-content\/uploads\/555.png\" alt=\"\">\n    <\/div>\n                <figcaption>Kotlin code is more compact than the same code in Java.<\/figcaption>\n    <\/figure><\/div>\n\n<div class=\"wp-block-lazyblock-banner lazyblock-banner-ZJdCUP\"><div \n  class=\"banner\n   \n  \" \n  >\n    <div class=\"banner__body\">\n        <h2 class=\"banner__h\"> We release projects for online and offline business<\/h2>\n        <div class=\"banner__content\">\n            <p><strong>We work with businesses of any scale.<\/strong> Our clients include international companies, large and medium-sized businesses, and startups.<\/p>\n<p><strong>Telecom<\/strong>: cellular operators, Internet service providers.<\/p>\n<p><strong>Finance<\/strong>: electronic payment systems, insurance companies and brokers.<\/p>\n<p><strong>Retail<\/strong>: stores, trade networks.<\/p>\n<p><strong>Internet advertising<\/strong>: advertising agencies, advertising networks.<\/p>\n<p><strong>Medicine<\/strong>: clinics, medical services.<\/p>        <\/div>\n                            <div \n              class=\"banner__button button js-form-modal\n               button_style_light-on-promo2\">\n              Discuss or order development                          <\/div>\n            <\/div>\n    <div class=\"banner__photo\">\n        <img decoding=\"async\" src=\"https:\/\/orbitsoft.com\/blog\/wp-content\/uploads\/friendship.png\" alt=\"\" class=\"banner__img\">\n    <\/div>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Kotlin is a language developed by a Russian company called JetBrains.
