SubmitCheck
App Store submission preflight, built from the realities of shipping iOS software.
SubmitCheck compares build metadata, App Store Connect configuration, and current Apple requirements to surface detectable gaps before review. Raw app binaries and Apple API private keys stay on the developer’s machine.
SubmitCheck is the first public release from emonster.dev—not the limit of the developer-tools division.

Illustrative findingVersion mismatch
Review
The version prepared in App Store Connect does not match the selected build.
No binaries or API keys were sent to our servers.
Built by developers, for developers.
The new division begins with a simple premise: release useful tools from the same experience used to build and ship software.
Proven internal foundations
Public tools begin with workflows emonster has used and refined through real software work.
Developer-focused products
Each release starts with a concrete problem developers need to solve.
Credibility before claims
We describe what a tool does, where its evidence comes from, and what remains outside its scope.
