The software development packages needed to develop, deploy, and manage mobile apps are made from many components and tools which allow a developer to write, test, and deploy applications for one or more target platforms.
Front-end development tools are focused on the user interface and user experience (UI-UX) and provide the following abilities:
• UI design tools
• SDKs to access device features
• Cross-platform accommodations/support
Notable tools are listed below.
First party tools include official SDKs published by, or on behalf of, the company responsible for the design of a particular hardware platform (e.g. Apple, Google, etc) as well as any third-party software that is officially supported for the purpose of developing mobile apps for that hardware.
Back-end tools pick up where the front-end tools leave off, and provide a set of reusable services that are centrally managed and controlled and provide the following abilities:
• Integration with back-end systems
• User authentication-authorization
• Data services
• Reusable business logic
Available tools are listed below.
With bring your own device (BYOD) becoming the norm within more enterprises, IT departments often need stop-gap, tactical solutions that layer atop existing apps, phones, and platform component. Features include
• App wrapping for security
• Data encryption
• Client actions
• Reporting and statistics
Many system-level components are needed to have a functioning platform for developing mobile apps.

Criteria for selecting a development platform usually include the target mobile platforms, existing infrastructure, and development skills. When targeting more than one platform with cross-platform development, it is also important to consider the impact of the tool on the user experience. Performance is another important criterion, as research on mobile apps indicates a strong correlation between application performance and user satisfaction. Along with performance and other criteria, the availability of the technology and the project's requirements may drive the development between native and cross-platform environments. To aid the choice between native and cross-platform environments, some guidelines and benchmarks have been published. Typically, cross-platform environments are reusable across multiple platforms, leveraging a native container while using HTML, CSS, and JavaScript for the user interface. In contrast, native environments are targeted at one platform for each of those environments. For example, Android development occurs in the Eclipse IDE using Android Developer Tools (ADT) plugins, Apple iOS develop…

According to a 2020 Industry Report on Applications, 46% of mobile app users have stated that they have stopped using or uninstalled an app due to poor performance. Design experts advocate for the following design principles to create successful and effective mobile apps:

Clutter-free screens: Keeps interactions quick and simple, allowing users to focus on one specific task rather than being overwhelmed with multiple features and tasks. Design experts strongly advocate for one task per screen and recommend breaking down long forms into pages and progressively revealing new tasks or fields to minimize clutter.

Reduce cognitive load: Makes user journey through the app seamless and preserves natural flow through the app. Design experts suggest incorporating autocomplete, spell-check, prediction text assistance, and dropdown menus to reduce cognitive load. Design experts also recommend the state of the app be preserved when users temporarily leave the app and re-enter so that users can continue their journey from where they have left off.

Simple navigation: Around 11% of people have uninstalled apps due to their complicated interface. Design experts state it is paramount to present the navigation bar visibly in your app to help users navigate to frequently used and high-priority screens instantly. They suggest the use of recognizable icons specific to the device operating system to help users easily take actions such as opening a menu, changing settings, going back a screen, and searching within a page. According to them, a user should not be confused while navigating the app, so an orderly, clear, and logical navigation flow drives engagement and discovery in the app.

Notifications: It’s reported that around 19% of users uninstall an app due to frequent push notifications. Notifications should be sent with careful planning according to design experts. Experts state notifications should be sent at a time most convenient to users in their time zone and the messages should be personalized to bring great value to them.

Speed Appearance: About 19% of people uninstall apps due to hang up issues. Design experts state it’s important to make sure the app is fast and responsive so that users don’t have to wait for content. They state developers should deliver content faster or give the perception of progress. Some approaches suggested by the experts are the use of skeleton screens which show the layout of the app with content grayed out, progress bars or loading spinners, tasks being carried out in the background and delivering the content quickly when the user requests for it, or giving users some tasks or content while they are waiting for a page to load.

Usability: Approximately 85% of mobile users use their phone with one hand, thus design experts state it is important that the top-level menu, frequently used controls, and common action items are within the reach of the user’s thumb. They also stress the importance of readability and it’s recommended that the text size is at least 11 point font so that users can read it at the typical reading distance without zooming in. It is recommended that headers and titles on th…
