No, it is NOT a builder and it is NOT an automated service.

Your application development is done manually by our specialist using Android Studio and Xcode tools. All applications are tested before publishing.

You will be able to send Push notifications manually using the Onesignal panel. This is a special panel from

Such push notifications are sent to all users of the application, there is an opportunity to write the title of the message, text, there is some filtering by recipients.

The app has NO hidden functionality, no left program code, no ads, we don’t steal data. All app analytics data is stored on your accounts.

We are interested in providing a quality service. Applications are developed using cleanly written program code and support the latest requirements.

You pay for the development of the app once, once the app is ready, there are no subscription fees. If you will need technical support, this service is paid separately.

You can convert a website into an app with almost anything.

The advantage will be if your website will have a responsive layout or have a mobile version, use current web technologies, fast loading speed and no errors on it.


Creating a developer account on Google Play requires a one-time registration fee, which is subject to change. Now the fee is $25. Check the official Google Play Developer Console to register developer account.

The Apple Developer Program has an annual fee, which is $99/year. This fee allows you to publish and distribute apps on the App Store. Check the Apple Developer website for the most current pricing information.

The time it takes for your app to be published on Google Play can vary. Typically, it takes 1-2 days to a week for the initial review, but the entire process may take longer depending on the complexity of your app and any required modifications.

The App Store review process usually takes from 1-2 days to few weeks, but it can vary based on factors such as app complexity, adherence to guidelines, and any requested changes during the review.

For Google Play, you can find detailed information on the Google Play Developer Policy. This document outlines the rules and policies that apps must adhere to for publication. Visit the Google Play Developer Policy page for the latest guidelines.

For the App Store, refer to the App Store Review Guidelines provided by Apple. These guidelines cover various aspects of app design, functionality, and content. Access the App Store Review Guidelines on the Apple Developer website for the most up-to-date information.


The Android App Bundle is a publishing format introduced by Google for Android applications. It is a more modern alternative to the traditional APK (Android Package) file.

The AAB contains compiled code and resources, and it differs by including multiple device configurations and language resources in a single, optimized package.

Google Play uses the AAB to generate APKs tailored to individual devices during the app installation process.

Yes, while the Android App Bundle (AAB) is the preferred format for publishing on Google Play, developers can still generate APKs from the AAB for testing or distribution through alternative app stores.

However, Google Play encourages the use of AAB for its benefits in optimizing app delivery and reducing download sizes.

App signing is the process of digitally signing your Android app with a private key to verify its authenticity. It is crucial for app security and integrity, ensuring that the app has not been altered or tampered with during distribution.

A keystore is a file that contains cryptographic keys and certificates. In app signing, it stores your signing key.

During the app’s release, you provide the keystore file and password to sign the app. It’s crucial to keep the keystore secure, as losing it may complicate app updates.

No, you cannot change the signing key for an app after it has been released. The key is tied to the app’s identity, and changing it would be equivalent to releasing a completely different app. It is essential to safeguard your signing key and keystore.

No, Google Play does not support rolling back to a previous version of an app after updating with an AAB.

Ensure thorough testing before releasing updates to avoid issues, as users will receive the latest version available on the store.


The IPA file is the final distribution package for an iOS app that is submitted to and downloaded from the App Store. It contains the compiled executable code, assets, and necessary metadata for the app.

Developers generate the IPA using Xcode during the app’s development and submit it to the App Store for distribution.

A Distribution Certificate is a cryptographic key pair used to sign your app and associate it with your Apple Developer account. It is essential for submitting your app to the App Store.

We generate a Distribution Certificate in the Apple Developer Center and use it to sign your app before submitting it for review.

No, the Bundle ID and App Store Connect App ID are unique identifiers tied to your app’s identity on the App Store. Changing them would essentially create a new app.

It’s crucial to choose these identifiers carefully during the initial setup.

Yes, you can make changes to your app before it is approved during the review process. Simply upload a new build with the necessary modifications through App Store Connect.

However, once the app is approved and live on the App Store, certain changes, especially those related to the app’s identity (Bundle ID, App Store Connect App ID), cannot be modified.

During the review process, you can make changes to the app’s metadata, screenshots, and other non-binary elements in App Store Connect.

However, any changes requiring a new build (code modifications, feature additions, bug fixes) will necessitate the submission of a new version for review.

That means we have to start all over again. So, this way, once the publishing process has started, we can’t change anything.
