Filling information (sometimes a copywriter may be needed).
Testing (this stage of work takes a lot of time – only after finding and fixing all the shortcomings can the application be released “into the world”).
Bugfixing – latest technical improvements.
Delivery of the project to the client.
Placing applications on Google Play and the App Store is the bulk of the promotion work. Dedicated specialists issue requirements (keys – by which accompanying texts are written, placements, etc.), thanks to which the application is tested and approved by app stores and becomes available to a wide audience.
If this application is for internal communication (B2B), then this block of work can be skipped.
Team: project manager, Android / iOS developer, backend and API developer, QA specialist.
