Independent Apple developer
Custom apps for iPhone, iPad, Apple Watch and Mac.
I design, build and ship native apps for Apple platforms, from the first sketch to the App Store and every update after. You work directly with a senior engineer who has done this at Apple, Microsoft and Schlage.
What I build
One developer for every Apple screen your customers use.
Each of these is something I've already shipped in my own apps, so you're not paying for me to learn it.
iPhone and iPad
Native SwiftUI apps that feel at home on Apple's devices, from a one-screen utility to a full product with sync and subscriptions.
CardDog
NotiminderApple Watch
Watch apps that do real work on the wrist, not just mirror the phone. Digital Crown control, direct Wi-Fi connections and hands-free starts.
Mac
Mac apps that share code with iPhone and iPad but behave like proper Mac software, with menus, keyboard shortcuts and windows.
NotiminderOn-device intelligence
Apple Intelligence, Vision and pose detection running on the device, so features are fast and your users' data stays private.
NewSwingNotiminderiCloud sync and sharing
CloudKit sync across a person's devices, and shared databases for households and teams, with no servers for you to run.
CardDogNotiminderHardware and connected devices
Apps that talk to locks, shades, mixing consoles and other hardware over Bluetooth, NFC and the local network.
FadebankShipped apps
Live on the App Store today.
Designed, built and published by Quivtec. Each one is private by design, with no ads, no tracking and no accounts.
Photos Prime
Ask for any photo. A photo library you ask instead of browse. Type what you want to see, like “Lisbon in 2026” or “flowers”, and every match fills the screen. Your library stays ordinary files you own.
Verse of Wisdom
The King James Bible, offline. The complete King James Version on Apple Watch and iPhone. Every book and chapter is built in, the watch app works on its own, and your place follows you between them.
Notiminder
Notes that remind you. Notes and reminders fused into one simple thing. Write it down, and if it matters, give it a time, a place, or both.
NewSwing
See your swing the way a coach does. Records your golf swing, finds every key position, and tells you what's working and what to fix.
Fadebank
A mixer remote for the person running sound. Turns an iPad, iPhone or Apple Watch into a control surface for an OSC digital mixing console, so you can stand in the room and hear what everyone else hears.
CardDog
The watchdog for your wallet. A fast, private expense tracker that shows exactly where your money goes. No bank logins and no sign-up.
Emoji Word Match
A calm matching game for early readers. Tap two tiles with the same word and they lift off the board. The word is shown big and read aloud, so every match is a tiny reading lesson.
Ballast Descent
Ball weight is everything. A weighted ball falls through a shaft that rebuilds itself beneath you, with the Void grinding down from above.
See them all on Quivtec's App Store page.
