Apps by Caplaz
The app catalog
These are the apps by Caplaz — every one built and maintained here, every one downloadable right now. Four apps, zero “coming soon.” PatternSpace is the macOS powerhouse; LightSpace Connect is the mobile-friendly one.
PatternSpace

The macOS pattern generator for display calibration.
PatternSpace drives test patterns from your Mac to any display over Metal — SDR and HDR, with P3 and BT.2020 PQ presets — or straight to a reference monitor over DeckLink SDI, bypassing the OS entirely. Automated by ColourSpace, CalMAN, and PGenerator over an open JSON protocol (there’s a Swift SDK, because of course there is).
$39.99 one-time for Pro, $39.99 for the SDI output add-on. No subscriptions, Family Sharing included.

LightSpace Connect

Professional display calibration, made mobile.
The portable patch generator: turn a phone, tablet, or TV into a test-pattern source for profiling any display. Direct screen output or wireless via AirPlay, Chromecast, and HDMI adapters. Speaks ColourSpace, LightSpace, and CalMAN fluently, in SDR and HDR.

Clocks in Motion

Time as a piece of art.
Twenty-four analog clock faces draw the current time with their hands — a living clock made of clocks, rebuilt from the ground up. Full-screen clock, Home Screen widgets, and an alarm clock with three wake-up animations (Pinwheel, Wave, Chaos — pick your violence level). Cast it to the biggest screen in the house over Chromecast or AirPlay, or run it natively on Apple TV, Android TV, and Fire TV.
iPhone, iPad, Mac, Apple TV, Android, Android TV, Fire TV. Light and dark themes, four accent colors, accessibility done properly.
$1, one time. No ads, no subscriptions.
