Services
One studio for the whole build
Appalanche designs, builds, and ships mobile apps, websites, APIs, and AI features for Australian businesses. Fixed scope or ongoing partnership: either way, you work directly with the engineer who ships it.
Mobile app development
An app your customers keep on their phone, not one they delete after a week. We design and build iOS and Android apps from a single codebase, faster to ship, cheaper to maintain, and native in look and feel. One team owns the whole journey, from the first wireframe through store submission, review support, and the updates that follow.
What we build
- Customer-facing apps
- Internal tools
- Offline-first sync
- Push notifications
- In-app purchases
- Store submission
How it's built
React Native & Expo, one TypeScript codebase, native iOS and Android builds, over-the-air updates.
Proof
Limbo, a group-trip planner with 5,000+ downloads, and My Love Your Love, a relationship-education platform with 10,000+ downloads. Both are live on iOS and Android; download figures are combined iOS and Android totals.
Websites & web apps
Your website is the first thing a prospect checks and the last thing that should lose you the deal. We build fast, search-friendly marketing sites and full web applications, customer portals, dashboards, booking flows, that load quickly, rank well, and turn visitors into enquiries.
What we build
- Marketing websites
- Web apps & portals
- Dashboards
- Booking & payment flows
- SEO-ready builds
How it's built
Next.js & React with TypeScript, server-rendered, fast, and search-friendly out of the box.
Proof
The My Love Your Love platform pairs its apps with a marketing website and a therapist-network directory, all built by us.
APIs & integrations
The plumbing that makes everything else work. We build robust APIs, model databases around your actual business, and connect the systems you already rely on, payments, CRMs, email, logistics, so data flows without anyone re-keying it. Documented, monitored, and built to be handed over, not held hostage.
What we build
- REST APIs
- Payments
- Third-party integrations
- Auth & user accounts
- Webhooks
- Data migrations
How it's built
Node.js & Express with MongoDB or PostgreSQL, plus the payment providers and third-party services your business already uses.
Proof
Limbo's offline-first sync and live flight alerts run on APIs and third-party integrations we designed and operate.
AI & automation
AI where it earns its keep, not a chatbot bolted onto the homepage. We build AI-powered product features and internal automations that remove real manual work: turning messy emails and documents into structured data, routing enquiries, drafting responses, and connecting AI agents to the tools your team already works in.
What we build
- AI product features
- Email & document parsing
- Chat & agent integrations
- Internal automations
- Human-in-the-loop review
How it's built
AI & LLM integrations wired into your product and internal workflows, with human review where it matters.
Proof
Limbo's AI email import turns forwarded booking confirmations into structured travel plans, parsed, confidence-scored, and reviewed before anything is added.
Two ways to work with us
Pick the shape that fits the work. Both come with the same senior engineering and the same direct line to the person building your product.
Fixed-scope project
Scoped, quoted, delivered. We agree on exactly what ships, you get a fixed quote in AUD, and we build to that scope on a clear timeline. Best when you have a defined product or feature and want it done properly the first time.
Ongoing partnership
A monthly retainer for product teams that need senior capacity. We slot into your roadmap, building features, maintaining what's live, and picking up the work your team can't get to, with Australian-timezone collaboration and no handovers to juniors.
Every project includes
Source code ownership
The repository can be set up under your control. Ownership of paid custom deliverables transfers on full payment, with no lock-in.
App Store & Play Store submission
Listings, submission, and review support handled end to end. Store approval and timing remain Apple and Google's decisions.
CI/CD
Automated builds and deployments from the first week.
Analytics
Know how the product is actually used from launch day.
Documentation
Written so the next developer is never lost.
30-day post-launch support
We fix defects against the agreed scope reported within 30 days of delivery, subject to our terms.
Tell us what you're building
Send through a brief, even a rough one, and we'll come back with an approach and a fixed quote within two business days. No obligation.
