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.






A growing lineup of Android apps designed around a single principle: do one thing well, and stay out of the way.
Adaptive equalizer that learns your listening habits and applies the right tuning for each track and genre automatically.
Lightweight music player with adaptive playback, background scrobbling, and seamless library access on Android Auto.
Curated nature, ambient, and binaural sound mixes for sleep, focus, and meditation — with offline asset packs.
Turn the area around your camera cutout into a flexible action bar — quick gestures, lyrics, and live activities.
Privacy-first black screen and biometric lock companion — keep your screen yours in public and shared spaces.
AI-powered job search with auto-apply, CV review, and ATS scoring — find roles that match you and apply with one tap.
Every app we ship is crafted with the same hands-on engineering and product care.
Each app is profiled, optimized, and tested across real Android devices before it ships — smooth animations, low memory, no jank.
Your data stays on your device. We don't sell or share personal information — every privacy policy spells out exactly what's collected.
Small APK sizes, minimal background work, and battery-aware design. Our apps respect your phone's resources.
Continuous improvement based on user feedback and new Android platform features — stability and polish ship every release.
Clean, accessible interfaces that follow Material guidelines and work well in light and dark mode out of the box.
Every app has in-app support chat. Real responses from the team that built it — usually within a day.
Decibel Studios is the name I publish my Android apps under — it's not a company, just a working name for my indie projects. Everything you see here is designed, engineered, and supported by me, Arshil Khan. No teams, no investors, no roadmap committees.
Have feedback, a support question, or a business inquiry? We'd love to hear from you.
We typically respond within 24–48 hours. For urgent app issues, include your device model and app version.
