Development of a mobile product has ceased to exist the privilege of large technology corporations with huge budgets. Today, almost anyone with an idea and a basic understanding of the logic of processes can create their own application for Android and iOS . The market for tools for no-code and low-code development is growing rapidly, allowing you to bypass the need to learn complex programming languages like Swift or Kotlin at the initial stages.
However, the path from idea to upload to the app store is full of technical nuances and pitfalls. It is important to understand that creating a product is not just about drawing beautiful buttons, but about thinking through the architecture, server part and user experience. In this article, we will look at what tools exist, how much developer accounts cost, and how to avoid common mistakes when developing on your own.
Choosing a development strategy: code or constructor
The first decision you have to make concerns the implementation method. The traditional way involves writing native code. For iPhone this is language Swift and environment Xcode, and for Android - Kotlin and Android Studio. This method gives maximum performance and full access to the smartphone hardware, but requires months of training.
An alternative is cross-platform frameworks such as Flutter or React Native. They allow you to write code once and run it on both platforms. This is the golden mean for those who are ready to learn to app, but want to save time. However, for beginners, visual constructors remain the most accessible option.
Platforms like Adalo, Bubble or Glide allow you to assemble an interface from ready-made blocks, like a Lego constructor. You drag elements onto the screen, set up connections between them and receive a ready-made file .apk or link for installation. This is an ideal start for testing a hypothesis without investing in expensive specialists.
⚠️ Attention: Free plans in constructors often limit functionality or add watermarks of the platform brand. For a commercial project, immediately plan your subscription budget.
Designing the interface and operating logic
Before opening any development tool, you need to clearly imagine how your application will work. Adding features randomly leads to an awkward product that no one wants to use. At this stage, a user scenario is created and thought through ( a prototype and a user scenario is thought through (User Flow).
Use paper and pen or specialized tools like Figma to draw screens. Determine what actions the user performs when logging in, how registration occurs and where the main control buttons are located. The logic should be intuitive so as not to require a long learning curve.
It is important to immediately determine what data the application will store. Will it be a simple task list running locally on the phone, or a complex social network with photos uploaded to the server? The choice of databases backend solutions depends on this. For simple tasks, the built-in capabilities of designers are often sufficient.
Before starting development, draw a diagram of the screens on paper. This will save hours of rework during the layout process and will help you see logical holes in the script.
Don't forget about adaptability. The interface should be displayed correctly both on small screens of budget smartphones and on large tablets. In the settings of most modern tools there is a preview for different screen resolutions, which is worth using.
Technical implementation: functionality assembly
The process of directly assembling the application depends on the chosen platform. In visual designers, you work with a palette of components. You add lists, input forms, maps, and media players and associate them with actions. For example, pressing a button Submit can trigger writing data to a table.
If you chose the programming path, you will need to configure the environment. To work with Android Studio you need to install JDK (Java Development Kit) and configure the emulator. The emulator allows you to test your application on a virtual device directly on your computer, without connecting a real phone.
Pay special attention to API integration if your application requires data from external sources. This could be the weather, exchange rates or payment system. Working with API requires an understanding of the request format JSON and authorization methods. Errors at this stage often lead to the application crashing upon loading.
☑️ Ready for assembly
During the development process, constantly save project versions. Using version control systems like Gitallows you to roll back if a new change breaks everything. Even in constructors there is a history of changes, but local backups will never be superfluous.
Testing and debugging before launch
The assembled project must be thoroughly tested. Errors that are not noticeable at the development stage can appear on real user devices. Testing is divided into several stages: functional, usability and cross-device. Ignoring this step leads to bad reviews and removal of the application.
For Android, the process of installing the test version is simple. You collect the file .apk or .aab and transfer it to the device. In your phone settings you need to allow installation from unknown sources. For iOS, the situation is more complicated due to the closed ecosystem Apple.
To install an application on iPhone without publishing it in the App Store, you will need a developer account and use the tool TestFlight. This is Apple's official beta testing platform. You upload the assembly to App Store Connect and invite testers via email or link.
| Platform | File format | Installation tool | Complexity |
|---|---|---|---|
| Android | .apk / .aab | Direct installation / ADB | Low |
| iOS | .ipa | TestFlight / Xcode | High |
| Web App | PWA | Browser | Medium |
⚠️ Attention: When testing on real devices, be sure to check the operation of the application when the Internet is poor. Many users experience an unstable connection, and the application should not freeze in such conditions.
What is ADB and why do you need it?
ADB (Android Debug Bridge) is a universal command line tool that allows your computer to communicate with your Android device. It is used to install applications, view system logs and debug code in real time.
Publishing in application stores
The final stage is entering the market. To do this, you need to register in the appropriate console panels. Google Play requires a one-time fee of $25. After payment, you get access to Google Play Consolewhere you fill out the description, upload screenshots and the application file itself.
The Apple ecosystem requires an annual payment. A developer account Apple Developer app costs $99 per year. The moderation process in the App Store is much stricter than that of competitors. Moderators check not only functionality, but also compliance with design guidelines, as well as the absence of hidden functions.
When filling out a store card, use keywords in the title and description for ASO (App Store Optimization). This will help users find your app through search. Be sure to add an attractive icon and promotional video if the functionality allows it.
Moderation time on Google Play usually ranges from 2 to 7 days, while in the App Store the process can take a week or more due to manual review.
It is worth considering that store rules change frequently. What was allowed yesterday may cause a build to be rejected today. Always check the latest requirements in the help sections for developers before submitting for review.
Project support and monetization
Launch of an application is not the end, but the beginning of work. You will have to constantly monitor user feedback and fix bugs. Mobile operating systems are updated annually, and the old application may no longer work on new versions Android or iOS.
The issue of monetization should be resolved in advance. There are several main models: paid download, subscription, in-app purchase or advertising. The choice depends on the type of product. Utilities often operate on a subscription model, and games operate through in-game purchases.
Special networks are used to connect advertising, such as Google AdMob or Unity Ads. You implement their SDK into the project, and advertising begins to be shown to users. It is important to maintain a balance so that ads do not irritate the audience and do not lead to the deletion of the application.
⚠️ Attention: Violation of monetization rules, for example, hidden subscription or fraudulent clicks on advertising, will lead to permanent blocking of the developer's account without the possibility of recovery.
Plays analytics plays a key role in development. Connect Firebase or AppMetricato understand how users interact with the interface. Data about which screen people close the app on will help you improve your product and increase audience retention.
How much does it cost to make an app yourself?
The cost varies from 0 to several thousand dollars. If you use the free plans of designers and do everything yourself, the costs will be minimal (only time). However, publishing on the Apple App Store requires $99/year, and on Google Play it costs $25 one time. Professional development tools can cost from $30 to $200 per month.
Do you need to know programming to create an application?
No, it is not necessary. Modern No-Code platforms allow you to create full-fledged applications, online stores and delivery services without writing a line of code. However, knowledge of the basics of logic and databases will significantly simplify the process and expand the possibilities.
Is it possible to release one app on Android and iOS at once?
Yes, it is possible. Cross-platform technologies (Flutter, React Native) and most designers allow you to export a project for both operating systems from one database. You don't have to make two different applications from scratch.
How long does it take to verify an app in stores?
On Google Play, automatic and manual verification usually takes from 2 to 5 business days. In the App Store, the process is strictly manual and can last from 3 to 10 days, depending on the workload of the moderators and the complexity of the application’s functionality.
What to do if the application is rejected?
You must carefully study the letter from the moderators, which indicates the specific reason for the refusal (violation of content rules, bugs, payment problems). After the comments are corrected, the application is sent for re-checking. Frequent failures can lead to account blocking.
