Deliver a release decision, not merely a build that launches

Yudun compares the original and protected candidates under the same conditions across upgrade, launch, critical flows, crashes, performance, rollout, and rollback so security and engineering can make the release decision together.

Are these problems holding back your app?

  • A vendor demonstrates installation but never runs the critical business flow
  • The tested file is not the package that will ship
  • A hardened build crashes and security and engineering cannot isolate the cause
  • Missing device or OS coverage is presented as compatibility passed

How Yudun handles them

  • Candidate identity binding

    Fix file digest, signing identity, version, and protection configuration so every evidence item refers to the same deliverable.

  • Performance and compatibility PoC

    Compare upgrade, cold launch, critical flows, crashes, and resources with conditions and uncovered scope recorded.

  • Failure isolation and release gates

    Separate build-chain, protection-policy, third-party SDK, and business-code causes and prepare rollout stop and rollback conditions.

Public assessment: compatibility considered installation, three cold launches, and critical business flows

The Yudun performance and compatibility center publishes a redacted candidate-level baseline method instead of treating one launch screenshot as stability evidence.

What the assessment disclosed

  • Established clean-environment installation and launch preconditions
  • Recorded three cold launches and critical business-flow behavior
  • Kept package size, crashes, device matrix, rollout, and rollback in scope

Scope: The public baseline applies only to declared candidates and conditions; it does not promise a universal compatibility rate.

From assessment to delivery

See the delivery method
  1. 01

    Set acceptance questions

    Define business paths, target devices, OS versions, and the actual risk the purchase needs to answer.

  2. 02

    Run a comparative PoC

    Test original and protected candidates under the same conditions and record pass, fail, and uncovered.

  3. 03

    Form the release decision

    Summarize risk, limitations, rollout, and rollback so the result can enter release approval.

Questions before purchase

Does successful installation and launch mean acceptance passed?

No. Critical business paths, upgrades, failures, compatibility, performance, and rollback still require verification.

What should be checked first after a hardening crash?

Confirm candidate identity and reproduction conditions, then isolate application launch, class loading, native loading, resources, and third-party SDKs.

Is average performance enough?

No. Record conditions and include tail behavior, crashes, package size, memory, and actual critical paths.

What if a system version is unavailable?

Mark it as uncovered and restrict the rollout scope. Results from another version cannot replace it.
