Building Apps That Actually Work

We've been creating mobile applications since 2019, and our approach is pretty straightforward — we focus on solving real problems rather than chasing trends.

How We Started (And Why We Keep Going)

Back in 2019, I was frustrated with app development companies that promised the moon but delivered basic functionality months behind schedule. So we started Deviceinstrument with a different idea — what if we actually listened to what clients needed and built exactly that?

Our first project was a delivery tracking app for a local restaurant chain. Nothing fancy, but it needed to work reliably during lunch rush. That experience taught us something important: great apps aren't about impressive features — they're about solving specific problems without breaking.

Here's what we learned: Most businesses don't need revolutionary technology. They need apps that their customers can use easily and that don't crash when traffic spikes. That's harder to build than you might think.

Since then, we've built apps for everything from inventory management to customer loyalty programs. Each project teaches us something new about what works in real-world conditions versus what looks good in demos.

The People Behind Your Apps

Siriporn Khanthavong

Lead iOS Developer

Siriporn has been writing Swift code since Apple released it. She's the one who catches those subtle bugs that only show up when users actually start using the app in unexpected ways.

Bounmy Sisavath

Android Development Lead

Bounmy knows Android fragmentation better than anyone. She's the reason our apps work smoothly on everything from flagship phones to budget devices that are three years old.

Our full team includes designers who understand user behavior, developers who've seen every possible edge case, and project coordinators who keep everything on track. We're not trying to be the biggest app development company — we'd rather be the one that delivers exactly what we promise.

Our Development Process

We've refined this approach over 47 app launches. It's not revolutionary, but it consistently produces apps that work as expected.

Discovery Without the Fluff

We start by understanding what your users actually need to do with the app. Not what would be cool to have, but what they'll use daily. This prevents scope creep and keeps development focused.

Design for Real Conditions

Our designs account for things like poor network connections, users with limited tech experience, and the fact that people use apps while distracted. Pretty designs that don't work in real life aren't actually pretty.

Build and Test Continuously

We test on actual devices throughout development, not just in simulators. This catches performance issues and usability problems before they reach your users. It takes longer upfront but prevents expensive fixes later.

Launch Support That Actually Helps

App store approval can be unpredictable. We handle the submission process and provide real support for the first few months after launch — not just a phone number that goes to voicemail.
