Yeti Technology · Apps + AI Studio · Sydney, AU
Bespoke apps and AI agents, built with taste.
We design and build premium mobile apps — native and cross-platform — and the agentic AI and automation that put them to work, with senior review from idea to launch.
Designed around how each platform behaves, not templates.
Most apps feel assembled. We build apps that feel designed.
Yeti Technology is a bespoke apps and AI studio, not a generic software shop. We do two things properly: premium mobile apps — native and cross-platform — and the agentic AI and automation that make businesses run better. Designed with taste, engineered to a standard, finished to the level users notice but rarely describe.
That focus is deliberate. The teams behind the products people trust are not generalists who do everything; they are specialists who obsess over interaction, performance, and the conventions of the platform they build on — whether that is the phone in someone's hand or the workflow a business runs on. That is the room we choose to compete in.
We work with founders, startups, and established organisations — from Sydney and across Australia to Nepal and beyond — who care about quality, usability, and long-term product value.
Right tool, chosen honestly
Swift and Kotlin when the platform is the product. Flutter or React Native when one codebase serves you better. We build both, so the recommendation fits your product — and we tell you why.
Design-led
Every screen is designed around speed, clarity, and native platform behaviour — including the states most teams forget: empty, offline, error.
Built to be kept
Tested architecture, documented decisions, automated releases. We build every app as if another team will inherit it — because one day, one might.
Nine services. Two disciplines.
Everything we offer serves two pillars — premium mobile apps and agentic AI — designed, engineered, launched, and kept healthy to one standard.
iOS apps built in Swift and SwiftUI that feel at home on the platform — fast, precise, and finished to the standard Apple users notice.
- SwiftUI with UIKit where it earns its place
- 120Hz-smooth, gesture-driven interfaces
- App Store review handled early
- Widgets, App Intents & platform features
Not sure which one you need?
Tell us where the product is today. We'll tell you, candidly, what we would do next — and what we wouldn't.
Native or cross-platform. We'll tell you straight.
We build with Swift and Kotlin, and with Flutter and React Native. That means platform advice with no stack to defend — here is how the decision actually falls.
The app is the product
When you compete for a place on the home screen, feel is strategy. Native navigation, gestures, and haptics match the calibration users carry from every other app on their phone.
Deep device work
Camera pipelines, sensors, offline sync, background work — used directly in Swift and Kotlin, with the platform’s newest capabilities available the year they ship.
A decade-long horizon
Swift and Kotlin are the platforms’ own languages. For a product you intend to run and staff for years, that is the lowest-risk foundation mobile offers.
One team, both stores
A budget that must cover iOS and Android well is often better spent on one excellent Flutter or React Native codebase than two thin native ones.
Internal & operational tools
A captive audience, standard UI patterns, and a premium on iteration speed — the profile where a shared codebase simply wins the trade.
Validate before you specialise
Test the market on both stores at once, instrumented properly. Real usage then tells you honestly whether — and when — going native is worth it.
Either way, the advice comes before the invoice. We build both, so the recommendation is about your product, not our pipeline — and if the honest answer is “not an app at all”, we say that too.
From first sketch to the store.
Six deliberate stages, one accountable team.
Base Camp · 5,364 m
Product & UX discovery
Who the app serves, the jobs it must do brilliantly, and the constraints that shape it — agreed before a single screen is drawn.
Camp I · 6,065 m
Interface design & prototype
Flows, states, and high-fidelity design on real platform components — prototyped and tested on device, where thumbs are real.
Camp II · 6,400 m
Platform architecture
Data model, sync strategy, and state architecture — the one-way doors — designed by senior engineers before the build accelerates.
Camp III · 7,162 m
Build & iterate
Short iterations, working builds on your own device every week, and a backlog re-ranked by what testing reveals.
Summit · 8,849 m
Test, polish, launch
Profiling on real hardware, accessibility passes, store review handled early — then a staged, monitored release.
The Descent
Maintain & improve
Crash and performance monitoring, OS updates tracked before they bite, and the next improvements sequenced by evidence.
Design taste + serious engineering.
Plenty of teams can code an app that works. Far fewer can combine UX judgement, platform depth, performance discipline, and engineering that stays maintainable — in one room, on one product. That combination is the studio.
Design taste
Knowing what to leave out. Typography that holds a hierarchy, motion that carries information, and the restraint to stop before an interface becomes a performance.
Platform knowledge
The conventions, the review guidelines, the APIs that shipped last WWDC and I/O — and the judgement to know which ones your product should actually use.
Performance obsession
Budgets for startup, frame time, and memory — set early, measured on the phones users actually own, and enforced in CI so fast stays fast.
Maintainable engineering
Architecture your next team can read, tests where they pay for themselves, and releases boring enough to run on a Friday.
We care about the small details users feel but rarely describe — the transition that tracks a thumb, the list that never stutters, the empty state that was designed on purpose.
Equipment we trust.
A deliberately small kit: the platforms' own tools, plus what it takes to design, measure, and ship well. No fashion-driven rewrites. Tap any item for its role.
The apps we're built to build.
Much of our client work ships under their name, not ours — so rather than parade logos, here is the shape of the work we do best.
Capability 01Consumer & Lifestyle
Consumer products with a high polish bar
Apps competing for a place on the home screen: onboarding that earns permission, motion that tracks the thumb, and interfaces that hold up next to the best apps on the phone.
- Gesture-driven, interruptible navigation and transitions
- Subscriptions, StoreKit and Play Billing done to platform spec
- Widgets, App Intents, and notifications that respect the user
Capability 02Field & Operations
Field & operations apps that work offline
Apps for the depot, the site visit, and the patchy regional network: local-first data, conflict-safe sync, and capture flows — camera, barcode, signature — built around failure modes.
- Offline-first storage with reliable background sync
- Camera, scanning, GPS, and Bluetooth integrations
- Battery-aware background work that survives OEM restrictions
Capability 03Commerce & Media
Commerce & content with native speed
Catalogues, checkout, and media that feel instant: image pipelines tuned per screen, payment sheets on platform rails, and lists that stay smooth at ten thousand items.
- Apple Pay and Google Pay on native payment rails
- Image and video pipelines with strict payload budgets
- Search, deep links, and app shortcuts that convert
Capability 04AI & Automation
Agents & automation behind the scenes
The workflows nobody screenshots: agents that triage, draft, and reconcile against your real systems, and internal tools that replace spreadsheet glue — auditable end to end, with people approving what matters.
- Agents with tool use, structured outputs, and audit trails
- Human approval gates where judgement and risk live
- Integrations with the systems you already run
A studio, not a factory.
Yeti Technology is a founder-led team of product specialists — designers and engineers who have spent their careers on the details that make software feel right, from the home screen to the back office.
Senior people, small team
The people who scope your product are the people who design and build it. No hand-offs to a delivery team you never met.
Production experience
We have shipped and operated real apps through store reviews, OS migrations, and the 2am incident — and we build like people who have.
Two ranges, one studio
Sydney business hours and Australian credibility, with engineering reach spanning Nepal and beyond. The name is not an accident.
Fair questions, straight answers
Should we build native or cross-platform?
It depends on the product — and we build both, so the advice is not a sales pitch. Native Swift and Kotlin set the higher ceiling for platform feel, device capability, and long-term stability: the right call when the app is the product. Flutter or React Native earns its place when one codebase genuinely serves you better — internal tools, content-led products, or a budget that must cover both stores well rather than one platform twice. We will tell you which, and why, in the first call.
Do you build both iOS and Android apps?
Yes — natively on each platform (Swift and SwiftUI on iOS, Kotlin and Jetpack Compose on Android), or in Flutter or React Native where one codebase is the right call. Either way, we often recommend launching one platform first and following with the second once the product has settled, and we design to each platform's conventions rather than mirroring one across.
What kind of AI work do you take on?
Specific, scoped work: AI features inside products, agents that carry a defined workflow end to end, and business process automation. We build on mainstream models — Claude, GPT — with evaluation suites before launch and human review wherever judgement matters. What we do not do is "AI everything" transformation consulting.
Can you automate our internal workflows?
Yes. We map the real process first — including the exceptions everyone works around — then automate the repetitive, rule-heavy parts and build internal tools for the rest. AI where it measurably helps, deterministic code where it is enough, and human approval gates where the stakes are high. Every automation ships with the same documentation and support terms as our apps.
Can you redesign an existing app?
Yes, including apps we did not originally build. We start with a UX audit grounded in your analytics and store reviews, then redesign in stages your team can actually ship — foundations first, then flows in order of impact — so improvement reaches users in weeks rather than waiting on a big-bang release.
Do you work with startups?
We do. Our MVP-to-production service is built for exactly that: a focused first release scoped around what the product must prove, on foundations that carry through to scale. You own the code fully, and the codebase is documented and handed over so you can hire your own team whenever you are ready.
Do you work with Australian businesses?
Yes — we are Sydney-based and work with clients across Sydney, Melbourne, Brisbane, Perth, Adelaide, and Canberra, on-site where it helps and remotely where it does not. We also deliver for teams in Nepal and internationally.
Can you help with the app store launch?
End to end, for both stores. That covers privacy disclosures and review requirements, metadata and screenshots, TestFlight and Play testing tracks, staged rollout, and the crash and performance monitoring that keeps the first weeks after launch calm.
How do you use AI in development?
AI accelerates the mechanical parts of the work — boilerplate, test scaffolding, refactoring — never the judgement. Every pull request goes through senior developer code review, and architecture, security, and release decisions are always made by people. The full workflow, including every human review gate, is documented on our process page. That discipline is also why clients trust us to build agentic AI for them: we hold what we ship to the same rules we work by.
What happens after launch?
Every build includes three months of free post-launch support: bug fixes within the delivered scope, crash investigation, store review issue support, and monitoring while the app finds its feet. New features and larger changes are planned separately, and the exact inclusions and exclusions are spelled out on our process page before you commit.
Do you also handle backend and API integration?
We integrate with your existing backend and APIs as part of every build, and where a mobile product needs supporting services — authentication, sync, notifications, a backend-for-frontend layer — we design and build them in service of the app. The app is always the product; the backend work exists to make it excellent.
