Solo Indie Developer

Android apps,
crafted with care.

Hi, I'm Arshil Khan — I design, build, and ship Android apps under the name Decibel Studios. It's a working name, not a company: every app here is made and supported by one person, end to end.

Why Decibel

Built with excellence

Every app we ship is crafted with the same hands-on engineering and product care.

◆

Quality First

Each app is profiled, optimized, and tested across real Android devices before it ships — smooth animations, low memory, no jank.

◈

Privacy Focused

Your data stays on your device. We don't sell or share personal information — every privacy policy spells out exactly what's collected.

▲

Lightweight & Fast

Small APK sizes, minimal background work, and battery-aware design. Our apps respect your phone's resources.

●

Regular Updates

Continuous improvement based on user feedback and new Android platform features — stability and polish ship every release.

◐

Thoughtful Design

Clean, accessible interfaces that follow Material guidelines and work well in light and dark mode out of the box.

◑

Responsive Support

Every app has in-app support chat. Real responses from the team that built it — usually within a day.

About

A one-person studio with operator DNA

  • ✓ Active on Google Play since 2016
  • ✓ Privacy-first — no third-party tracking beyond what's disclosed
  • ✓ Solo-built and personally supported by the same person who shipped it
