Questions before starting a mobile project

Do you build mobile apps for YouTubers as well as games?

Yes. Depending on the channel’s product idea, we plan iOS and Android apps with the interface, content flow, accounts and server work they need. The brief defines which features belong in the first release.

Can I commission a story-led mobile game with level progression?

Yes. We can plan the character, gameplay, missions and levels together. The first playable build is used to assess the controls and core game loop.

Must the first release launch on both stores?

It can target iOS, Android or both. The choice depends on your audience, scope and budget. Each portfolio product’s platform availability is shown through its own store links.

What should I share to get started?

Send your channel link, audience, app or game idea, characters we can use and target platforms. These help us define the first release and the project deliverables.
