Native and cross-platform iOS and Android apps for startups and businesses — from first prototype to App Store launch and beyond.
A good app earns its place on someone's home screen. It opens fast, does its main job brilliantly, and keeps working when the connection drops. That's the bar we build to.
DEVR Tech is a software studio with teams in Singapore and Malaysia. We've designed and shipped mobile apps for organisations of every size — from a travel companion app for the Singapore Tourism Board to a maid-agency hiring app for Nanyang Employment Services and a social fitness platform for move-mo.
We handle the whole journey: scoping, UX design, development, backend and APIs, App Store and Google Play launch, and support after release. You get one team accountable for the result, not a chain of hand-offs.
Booking, ordering, membership, and discovery apps your customers open every day.
Apps that connect two sides — clients and providers, buyers and sellers — with profiles, listings, and search.
In-app payments, live updates, and notifications that keep users coming back.
The APIs, databases, and admin tools behind your app, built alongside it rather than bolted on.
One React Native or Flutter codebase for iOS and Android, so you launch on both for less.
Store listings, submission, and review handled for you, plus updates after launch.
For most products, a cross-platform framework like React Native or Flutter is the right call. You maintain one codebase instead of two, features ship to iOS and Android at the same time, and the budget goes further.
Fully native development makes sense when an app leans heavily on device hardware or platform-specific features. And sometimes the honest answer is that you don't need an app yet — a fast, responsive web app may reach your customers sooner. We'll recommend what fits during scoping, and explain why.

We map your users, core features, and constraints, then scope the first release honestly.
Clickable Figma prototypes you can try on your own phone before we write production code.
Agile sprints with regular demos and test builds, so there are no surprises.
We handle store submission, monitor the release, and keep improving against real usage.

A mobile app that brings Singapore's attractions, itineraries, and experiences into one pocket-sized guide.

A platform that lets interior designers discover, compare, and source designer materials without the endless back-and-forth.

A maid-agency mobile app that lets clients browse, hire, and manage domestic helpers with ease.
Every app is different, so we scope before we quote. Cost depends mostly on the number of features and screens, how much custom design you need, the backend and admin tools behind the app, and integrations like payments.
It depends on scope, but most of our projects start in the low five figures. The biggest cost drivers are the number of features, custom design, backend work, and third-party integrations. Message us on WhatsApp and we'll send a ballpark and a free quote within 24 hours.
A focused MVP can ship in 6–10 weeks, and 85% of our projects launch within three months. Larger platforms take longer — we'll give you a realistic timeline before we start.
Usually both. Cross-platform frameworks like React Native and Flutter let us ship to iOS and Android from one codebase, which keeps cost and maintenance down. If your app depends on platform-specific features, we'll recommend native instead.
Yes. We prepare the store listings, handle submission and review, and support you through launch.
We don't disappear. We offer ongoing support, monitoring, and improvements — from bug fixes to new features and SEO.
