Create an application for Android

Good day.

My name is Alexey, I represent the Mobiwolf team — we have been developing mobile applications for Android for over 14 years and provide long-term technical support.

We can take on your Android project in Kotlin and guarantee exactly what is critical for you:

Our relevant experience

• Clear integration of AdMob ads (banners, interstitials, rewarded, adaptive blocks, eCPM testing).
… • Google Play Billing (subscriptions) — correct integration, validation, handling of cancellations/refunds.
• Minimum errors and no crashes — strict work with logging, ANR, Crashlytics.
• Push notifications via FCM: topics, custom payloads, background/foreground notifications, action handling.
• Experience in scalable development, when it is necessary to create dozens of similar screens.
• Simple, readable, and maintainable code, ready for further improvements.
• Ongoing support for publications in Google Play: updates, Google requirements, minor edits at a reasonable cost.

Technologies

• Kotlin (if necessary, we can offer alternatives — Jetpack Compose or hybrid, we can discuss).
• Firebase (Crashlytics, Messaging, Analytics).
• Google Play Billing v6.
• AdMob + mediation (if needed).

How we work

• Quick immersion in the project.
• Clear deadlines and transparent stages.
• Always stay in touch and support the application after release.

I am ready to receive a link to Figma to assess the exact timelines and cost of development.

I would be happy to collaborate and am ready to discuss details in personal correspondence.

Sincerely,
Alexey, Mobiwolf

Hello!
More than 8 years of experience in developing Android applications. We are ready to develop your project. However, unfortunately, until we familiarize ourselves with the design and technical specifications, it is difficult to estimate how much time is needed for development and what the cost will be. Please send a link to the design and the technical specifications with a description of the application's functionality.

Hello!
My name is Alexandra. I develop mobile applications and have experience with both Kotlin and Flutter (Dart) — including subscriptions, ads, push notifications, and stable publishing on Google Play.

Why my experience is suitable

I have worked with AdMob — fast ad display without delays, correct initialization, and fill rate checking.

Experience implementing Google Play Billing: subscriptions, trial periods, status checking, purchase restoration.

… I guarantee stability — no crashes and proper error handling.

I have configured FCM for push notifications, including tokens, topics, and custom messages.

I write clean, clear, easily modifiable code.

I can take the application for further support and regular updates — Google really often changes requirements.

Regarding the development stack

Yes, I can complete the task in Kotlin, as specified in the technical specifications — I work with Android SDK, Jetpack, Coroutines, Billing, AdMob, and Firebase.

But when it comes to practicality and future scalability, Flutter (Dart) will allow:

to easily release an iOS version later without starting from scratch;

to adapt the application for the Web if necessary;

to maintain one codebase instead of two;

to make changes and updates faster (ideal if the application will grow).

At the same time, all the mentioned functions — AdMob, Billing, FCM — are implemented just as reliably in Flutter.

I am ready to discuss both options and offer the optimal solution for your project.

About the project

I will do:

all pages according to the Figma layout,

replication of similar screens,

clean architecture,

support during publication.

I am ready to start after discussing the details. I would be happy to work on your application!
