iOS App Store & Android Google Play Release
A correct build can still fail at signing, distribution or store review. We address certificate/account ownership, testing tracks, target SDK requirements, staged rollout and recovery for iOS and Android releases.
Implementation scope
Xcode or Gradle builds succeed locally but fail in CI or with release signing.
Ship and update apps with repeatable builds, verified signing, beta testing and store release controls. We work against agreed platforms, repository access, constraints, milestones and acceptance tests—not a one-size-fits-all app package.

Frequently Asked Questions
Answers to your questions
Will Demonic Binary publish from its own developer accounts?
The recommended setup is publishing from customer-controlled Apple and Google developer accounts, with appropriately delegated permissions and documented signing ownership.
Can you guarantee App Store or Google Play approval?
No. Apple and Google control store review and policies. We can improve submission readiness, diagnose rejections and help correct issues.
Our Approach
How we work with your team
Discovery
We review your goals, existing environment and the systems or workflows involved.
Engagement planning
Code changes, integrations, production access and release support are agreed separately where needed. We define the delivery plan and responsibilities together.
Results and handoff
Your team receives the agreed implementation or findings, testing results and a clear next-step plan.
