Yes. Our AI solutions do stand out.

Mobile app screens designed by O2SOFT

Our experience in AI mobile apps.

Over 200 mobile app projects shipped, taking enterprises into the growth-hacking stage in an average of 8 months. Twelve years of builds and a GitHub bank let us deliver AI features swiftly and at a flexible cost.

Fan Club App

Millions of fans worldwide consume news, radio broadcasts, video content and fantasy league daily, with AI-personalised feeds on top.

Social Listening & Sentiment Analysis

A custom take on off-the-shelf tools that are too costly for a VSB or SMB, masked as a Student Community Hub app.

Full-option Ordering App

A reverse ordering app with more features than OpenTable that helps business owners maximise their on-prem bookings.

Native iOS apps

Swift apps built and tested with Xcode and XCTests, so the experience feels at home on every iPhone and iPad.

Native Android apps

Kotlin and Java apps built in Android Studio for the performance and stability enterprise users expect.

On-device AI features

Intelligence that runs on the phone itself, so apps stay fast, private and useful even without a signal.

Who you actually work with.

The same cross-functional team runs your app from the workshop to launch, with an AI engineer working next to the product people from day one.

Resources are matched to each phase, so you only pay for the people the work needs at that point.

Business Analyst
Gathers business requirements and maps your needs and wishes in the one-day workshop
Design Lead
Wireframes, workflows and the solution design your users will touch
Project Lead
Scope, timeline, financial investment and your single point of contact
AI engineer
On-device and cloud AI features, model choice and the accuracy numbers you are shown
Full-stack leads
Front-end and back-end build, delivered in scrum-based sprints
QA team
Tests every new feature before it is added to the next sprint

Three phases, from AI idea to working app.

Every phase has a timeline, deliverables and the people involved agreed up front, so nothing about the build is a surprise.

They truly went above and beyond everything that we asked of them. In many ways it felt like they had become members of the team as they worked with us through a rigorous testing process to ensure that the app worked seamlessly.

Everything You Need to Know

Can't find what you're looking for?

Web development, mobile app development, custom software development, and UI/UX design — plus the strategy and discovery work needed to make sure we're building the right thing before we build anything at all.

We spend a full day with your team to understand the business problem, map out the user journey, define scope and deliver a project plan with estimated cost and timeline. You walk away with a document you can use with any agency.

Retail, travel, real estate, education, hospitality and IoT. Each backed by shipped client work — see our case studies for the details.

We offer three models: dedicated team (monthly), fixed-price project (lump sum), and offshore delivery centre (headcount-based). The right one depends on scope certainty and timeline — we'll recommend during the first call.

Yes. We sign NDAs as standard practice before any detailed discussion. Just ask during the first conversation and we'll send ours or sign yours.

We send a summary of what we discussed, a rough scope estimate and a recommendation for the next step — usually a workshop or a detailed proposal. No pressure, no follow-up sequence.

What we are learning, written down.

Notes from delivery, not marketing posts. Read the blog

Let's build it.

Whether you are starting from an idea or rescuing something already in flight, the first conversation is free and useful either way.
