About Julien

🎯 Considering buying a mobile app but not sure if you're making the right choice?

I help you analyze the key data of an app for sale to project yourself concretely and secure your investment.

✔️ I give you a clear and honest view of the product's quality, performance, and potential.

🔍 What I offer:
✅ Analysis of business metrics (revenue, users, retention, acquisition costs)
✅ ASO & Visibility Audit (App Store & Google Play, keywords, positioning, reviews)
✅ Technical App Review (stack, code quality, dependencies, technical risks)
✅ Verification of overall consistency between provided data and market reality
✅ Evaluation of growth or resale potential
✅ Advice for negotiation and handover (handover, tools, team)

At the end of the audit, I will provide you with a clear and actionable summary report, along with my recommendations.

👨‍💻 About me:

. Owner and operator of several mobile applications
. I have bought and sold apps myself
. I understand numbers and technology (hybrid product/marketing/technical background)

👉 My approach: pragmatic, structured, independent. I don't sell dreams, I help you buy with full awareness.

Feel free to contact me to discuss your project.
