Mobile product studio
We ship focused mobile utilities—PassVault, our secure password manager for Android, is on Google Play. More apps are on the way.
Products
PassVault is available on Google Play—secure password management with encryption-first design. More products will land here as we ship them.
Smart, secure password management.
Store passwords, payment cards, bank notes, Wi‑Fi credentials, and more in one encrypted vault. Autofill logins fast, check breached passwords with DataGuard, and keep your master password known only to you.
Install count comes from the Play Store listing for PassVault (dev.xappstudio.passvault). Update this block as metrics grow.
How we work
A tight loop between design, engineering, and QA so you always know what ships next.
We align on users, constraints, and the outcome that matters—before a single screen is designed.
Product design, engineering, and QA move as one cadence with clear milestones and visible progress.
Store releases, analytics, and iteration loops so your app improves every week—not once a year.
Social proof
A few words from partners who care about craft, communication, and outcomes.

Marco Rossi
Founder, Studio Verde
“Performance and accessibility were treated as features from day one. Rare in mobile agencies.”
