About

The Developer Behind Texts Dev

Texts Dev is a freelance development studio based in Durgapur, West Bengal, India. What started as a passion for building Android apps has grown into a full-stack practice — with 10 live apps on Google Play, a flagship with over 500K installs, and a track record across diagnostics, productivity, finance, security, and communication apps.

Today, Texts Dev helps businesses and individuals turn ideas into real products — designing and building apps, websites, and custom software from the ground up. Every project gets the same hands-on, detail-obsessed approach that went into building a half-million-download app from scratch. No need to come with a design — we create it for you.

Case Study

From Zero to 500K Installs

How we built, launched, and grew a flagship Android app.

CPU Throttling Test

CPU Throttling Test

Diagnostics & Benchmarking

The Problem

Smartphone users and tech reviewers had no simple way to measure how much a device's CPU throttles under sustained load. Existing tools were either too technical or inaccurate.

The Solution

We designed and built a clean, one-tap benchmarking app that runs sustained CPU workloads and visualizes performance drops over time — with device ranking, detailed graphs, and shareable results.

What We Did

  • End-to-end UI/UX design
  • Native Android development (Kotlin)
  • Custom benchmarking engine
  • Device ranking system with 3,000+ devices
  • Play Store ASO & launch
  • Monetization (IAP + ads)

I like the UI and the app is really easy to use. Turns your phone into a mini space heater just as it should. This app proved that the Unisoc T760 on my phone is a good entry level chip able to sustain performance even when temperature had peaked at 43°C.

Just tested the CPU Throttle app on my setup during a heavy workload session. It effectively capped temps at 85°C, preventing crashes. Solid for basic throttling, though — dropped power draw by 20% without much performance hit. Worth it for laptops. 7/10.

FAQ

Common Questions

Everything you need to know before we start working together.

How long does a typical project take?

It depends on scope. A simple landing page or single-feature app takes 1–3 weeks. A multi-feature product with backend typically takes 2–4 months. We'll give you a clear timeline in our proposal before any work begins.

Do I get the full source code?

Yes — always. You get complete ownership of all source code, designs, and assets once the project is paid for. No lock-in, no dependencies on us.

How do payments work?

We work on a milestone basis. Typically: 30% upfront to begin, 30% at mid-milestone, and 40% on delivery. For smaller projects, it's 50/50. You never pay the full amount before seeing working software.

What if I need changes after launch?

Every project includes post-launch support (30–60 days depending on plan). After that, you can opt for a monthly maintenance retainer or request changes on a per-task basis. We're always available.

Do you sign NDAs?

Absolutely. We're happy to sign an NDA before any discussion. Your idea and data stay confidential.

Can you work with my existing app or codebase?

Yes. We can take over, fix, or extend existing projects — Android, React Native, web, or backend. We'll do a code review first to give you an honest assessment before quoting.

What if I'm not sure what I need?

That's exactly what the free consultation is for. We'll help you figure out the right scope, tech stack, and budget. No commitment — just a conversation.
