Apps, designed
with care.
I'm Victor, a solo founder in Sydney. I design and build iOS apps end to end. Two are live on the App Store.
For Australian tradies
Invoice Studio
Talk, snap or type. A tax invoice comes out.
Case 01 · Live since 29 Aug 2026
Invoice Studio.
Paperwork, done from the ute.
Australian tradies lose hours a week to paperwork: carbon-copy invoice books, GST worked out by hand, chasing bank details.
Invoice Studio turns a voice note, a photo of a quote or a blank page into a ready-to-send tax invoice. GST is calculated automatically, and PayID details go straight onto the invoice so the client knows how to pay.
It started as a web app on 29 May 2026 and became a native-feeling iOS app on 29 August. That meant one codebase, two payment systems (Stripe on the web, StoreKit on iOS) and no framework underneath.

What I learned
It took three App Store review rounds. Every rejection was about a compliance detail, like a screen-recording permission or a link to the subscription terms, and never about the product. Since then I get the legal details right before the first submission, because they cost more time than any feature.
Case 02 · Live since 23 Oct 2026
Wirlo.
A puzzle that spins.
Pieces fall inward toward a rotating core instead of stacking in a grid. You spin the core, match colours and chain combos before it fills up.
It's built 100% native in SwiftUI and SpriteKit, with no game engine and no web wrapper. The circular loop has relatives, like Hextris. What's new is the layer on top: a live global leaderboard, share cards where no two are alike, and a signature move where you swipe up on a fully aligned ring to clear it.
It's free to play. Players can watch an optional rewarded video from Google AdMob to earn coins, buy coin packs, or take the Premium monthly subscription, which gives coins every month and removes all ads. Ads only play when the player taps to watch one, and there are never banners.
The idea for the mechanic came from a dream. Everything after that was rounds and rounds of design.
Real screen recording — home screen into an accelerated match. Built 100% native in SwiftUI + SpriteKit.
What I learned
A casual game for everyone is a different discipline from a tool for a niche. Every decision was tested against one question: would a total beginner get this in 10 seconds?
Design
The details are
the product.
Before any code, I design every screen and test it against real use. Here is how the two apps look the way they do, and why.
Wirlo · Identity and game design
One rule above all.
"Nothing may require interpretation. A coin is a coin. Continue is continue."
Many Wirlo players aren't gamers. There is no text tutorial: the first match is the tutorial. Hints react to what you do, never before, and each one shows only once. The main button has to be readable in under a second, and every touch target is at least 44 points.
A mark that looks drawn, not typed
The "W" isn't a letter from a font. It's four coloured strokes with round caps, tilted 10°, and the last one sits higher. The gaps stand for the piece that hasn't snapped in yet.
Colour tuned for long sessions
The brand colours are vivid. In the game they're desaturated by 12% so they don't glow against the dark background after twenty minutes of play.
One typeface, no exceptions
Quicksand replaced Poppins and the system font. Four weights cover all 10 languages with no fallback font.
Sound, motion, touch
There isn't a single audio file. Every sound is synthesised live on one pentatonic scale, so it all sounds like one instrument, and the hit sound rises as your combo grows. There's one gentle haptic tap per meaningful event and nothing on every frame. Animation follows the iPhone's own Reduce Motion setting.
11 rounds of prototype
The game was designed as an HTML prototype first. The approved prototype became the contract for the native build.
- Rounds 3–5: readable surfaces, then a three-band layout
- Rounds 5–8: a frosted-glass bar with real content moving behind it
- Round 8: core sized to about 21% of the screen, calibrated by feel
- Round 9: symmetric lanes
- Rounds 10–11: no impossible situations, and every message moved to the top, because your eyes stay on the core
What I cut
Good design is also what you remove.
- Large animated logo on launch: it looked like letters appearing out of nowhere
- Vignette: it crowded the score; film grain does the job
- "?" help button: if a screen needs help, the screen is wrong
- Share card replaying the match: now it's generated art, so no two are alike
Invoice Studio · Brand and invoice design
A quiet tool, a beautiful invoice.
The app stays neutral. The invoice carries the brand.
The interface uses calm greys and a single teal accent, so the tradie's own invoice is the colourful thing on screen. Colour themes apply only to the invoice and its PDF, never to the app around it.
Neutral greys, one teal accent
8 colours, the client's choice
Four layouts, four personalities
Each layout fits a different kind of business, from a formal accountant to a bold, modern trade.
Three typefaces, three jobs
A clean sans for the interface, an italic serif so a company name feels like a signature, and a monospace font so every dollar lines up.
The brand outside the app
Every Instagram post comes from one fixed template: the same grid, colours and type in every post. A bold headline with its second line in teal, an italic serif subtitle, and white cards on a soft grid. The Reels follow the same rules, with no emoji. Consistency is what makes a small brand recognisable.
About
From zero to two apps
in one year.
I wrote my first line of code in February 2026. I have no CS degree and didn't do a bootcamp. I learned with AI as a coding partner, over nights and weekends after a full-time day job.
Since then I've shipped Invoice Studio and Wirlo end to end. I'm not a "no-code" story: I read the code, I ship it, and I fix it when it breaks at 11pm. Vikta is what I'm building while I learn, in public, one shipped product at a time.
