Mobile app development FAQs

Does APPS 365 GAMES build mobile apps as well as games?

Yes. We build mobile apps for iOS and Android as well as Roblox and mobile games. Eight of our own apps are live on Google Play, from an encrypted life planner to AI video apps.

How much does it cost to build a mobile app?

It depends on the app. A simple app with a few screens is a much smaller build than one with accounts, AI features and subscriptions. We scope it on a free call and send a written quote before work starts.

Can you add AI features to an app?

Yes. Our own apps use AI to read photos, make short videos, give voices to characters and write conversations, and they say clearly when something is made with AI.

Do you handle App Store and Google Play submission?

Yes. We prepare the listings, privacy details and builds for both stores and handle the submissions.

Can you build an app for our existing web product?

Yes. GrowFleet is an example: its app brings a web platform to the phone, with approvals straight from a notification.

Do you work with clients outside the UK?

Yes. We are based in London and work with clients worldwide.
