FAQ

Frequently Asked Questions

What is CyDev?+
CyDev is a browser-based toolkit designed to simplify everyday iOS and Android development tasks — certificate generation, UDID acquisition, IPA upload, launch screen creation, and more.
Do I need to install anything?+
Most CyDev tools work directly in your browser — no Mac, no Xcode, no Transporter. Some workflows may require additional tools or credentials depending on the task.
Is CyDev for professional developers?+
Yes. CyDev is designed for developers — indie developers, freelancers, and teams who need simple utilities for mobile development without dedicated hardware.
How much does CyDev cost?+
CyDev offers a 7-day free trial with all features open. After the trial, a simple annual plan: ¥78/year in Mainland China, $29/year for international users.
Does uploading an IPA mean you publish the app for me?+
No. CyDev provides IPA file upload to App Store Connect — no Xcode or Transporter needed. Uploading is not publishing: submitting for review, passing review, and releasing remain entirely in your hands.

Yes. We are continuously adding new tools based on developer needs. CyDev Analytics — including Mobile Vector Attribution — is already available, with more analytics features on the way.
