Where to start?


Share your idea

Simply describe how your dream mobile app should look & what functionality it should include.

Consider our solution

In return, we will send you working prototype of your App. We will send you also a quotation. 

Let's make an app!

If you like and accept our approach, we will create your mobile app. 

Further development

When your app is ready, we will share with you full source code. We can help you also publish your app in AppStore and Google Play. 

Unusual workflow

Our team redefined the approach to mobile app development. Conventional workflow includes both designer and developer in a team working separately on specific stages of development.

We do this a bit different.

In Stonks designers and developers work simultaneously over a specific part of an app. Such workflow significantly reduces time of creating functional UI. And developers can implement backend quicker. 

Reasons why we get things done fast

Aside to programming, we use no-code and low-code solutions to optimize workflow without affecting app quality.

We are small, remote-working team with comprehensive skills.

In Stonks we grow library of pre-made apps that can be adapted to your needs quickly.

Our apps are based on Flutter. It means we will create your app both for Android and iOS at once.

Does it sound good?
