App Development
One codebase, both app stores — an MVP your customers can install in weeks.
from $5,900 +GST · 6–10 weeks for an MVP
Sound familiar?
01
Two platforms, double cost
Native iOS + Android quotes double your budget before you've validated the idea.
02
MVPs that never ship
Scope creep and slow dev cycles mean the “3-month MVP” is still unreleased a year later.
03
Store submission maze
App Store review, signing certificates and privacy declarations stall launches for weeks.

We build cross-platform with React Native or Flutter — one codebase for iOS and Android — and cut scope ruthlessly to the features that prove your idea. We handle the full path to launch: design, build, TestFlight/Play beta, store submission and the compliance paperwork.

Frequently asked questions
Native or cross-platform — which do I need?
For 90% of small-business apps, cross-platform (React Native/Flutter) is the right call: one codebase, native feel, half the cost. We'll tell you plainly if your app is in the 10% that genuinely needs native.
What does an MVP cost?
MVPs start at $5,900 for a focused single-purpose app. Most sit between $8k and $20k depending on screens, accounts and backend needs. You get a fixed quote after a free scoping session.
Do you handle App Store approval?
Yes — certificates, listings, screenshots, privacy declarations and review responses are all included. Rejections are on us to fix.
What happens after launch?
You choose: a monthly care plan (updates, monitoring, OS compatibility) or a clean handover with docs. Most clients keep us on retainer for iteration once real users arrive.
Can you take over an existing app?
Usually yes. We start with a paid code audit ($490, credited toward work) so both sides know exactly what shape it's in before committing.
