Can you tell if this backing track was AI generated... just by listening? 🎸🤖
We recently shared a backing track and asked people to guess.

The twist?

It was AI generated.
Built using Dhun AI @fretpracticenow, our in-house music generation engine powering FretPractice.
The line between human-created and AI-assisted music is getting blurrier every day.
Could you tell the difference?

We're launching it publicly next week.

Drive link in first reply.

🎧 Listen and let us know: Human or AI?

My team recently sat down with @chandreshkudwa to talk about @fretpracticenow and the future of music practice and education.

🎸 Watch the conversation here:

As we continue building FretPractice, we're spending time with professional musicians, teachers, and creators to better understand the real challenges around practicing, tracking progress, student engagement, and running a modern music teaching business.

If you're a professional musician or educator, we'd love to hear your perspective. Your feedback is helping shape what we build next.

And if you're passionate about the future of music education, creator tools, or music-tech in general, we're always happy to connect and exchange ideas.

A consulting engagement I was working on recently wrapped up, which means I now have capacity for a few new projects.

Over the last 13 years I've helped build and scale mobile products at companies including JioCinema, Paytm, Gojek, Meesho and BYJU'S.

Areas I typically help with: Android & iOS, Kotlin Multiplatform (KMP), Mobile architecture, Performance & reliability, AI-powered mobile experiences, Engineering leadership

I'm a Google Developer Expert (Android/Kotlin), author of 3 Kotlin books, speaker, mentor.

If you're building or scaling a mobile product, let's talk. DMs are open.

Week 2 of building FretPractice 🎸

Plan for this week:
- Fretboard memorisation exercise
- Structured practice sessions
- Start integrating AI assist for Jamming

Goal: help guitarists stop guessing and start practicing with intention.

And guess what I'm using to build it for Android, iOS, Desktop and Web?

Compose Multiplatform. It enables me to build faster than any other platform, while sharing code, but still having stable and reliable codebase.

Started building FretPractice last week 🎸
Week 1 progress:
• Intelligent metronome
• Guitar tuner
Building in public and sharing the journey. If you play guitar (or know someone who does), I would love your feedback.

And if you have guitarist friends — please send it to them. 🎸
Early feedback from real players will shape what we build next.

[Rivu Chakraborty @rivuchakraborty]

I (as part of @MobrioStudio) started building a new app for guitarists last week. 🎸
It's called FretPractice.
The goal is simple:
Help guitarists practice smarter, not just longer.
Week 1 progress 👇

Mobile apps just got a whole lot smarter! 🧠📱
Massive thanks to Rivu Chakraborty for the deep dive into KMP & AI Agents. Seeing Gemini Nano and MediaPipe in action for cross-platform apps was a game changer! ⚡️

At DevFest Kolkata 2025 by @gdgkolkata , our founder @rivuchakraborty spent time with builders and founders discussing real mobile challenges — performance bottlenecks, legacy code, Kotlin Multiplatform, and scaling apps the right way.

That's interesting.
I'm also developing something in this space!
I'm working on Mobrio Files+, which is an AI-powered file manager targeting Android first, with a desktop version coming next.

Although my approach is a bit different and obviously open-source–driven, I'm still glad to come across this.

Sharing a short demo video that I first showed at @GDGAhmedabad #DevFest.

[Mobrio Studio @MobrioStudio]

We're working on an OSS AI File Browser. More details and Android alpha launch soon, with the desktop version following next.

2️⃣ Inefficient state management
Bad state handling leads to memory leaks and unnecessary re-renders.
A clean state tree = smoother performance.

3️⃣ Small fixes that are easy to overlook
A quick audit now can save you from crashes when traffic spikes.
