Lumina — lights that follow the sun
Set up adaptive lighting in your home in under a minute. Lumina shifts colour temperature and brightness throughout the day based on where the sun actually is at your location — so mornings feel like mornings and evenings feel like evenings.
No flows, no schedules, no per-lamp configuration. Add one Lumina Zone per room, pick a curve, done. Per-zone overrides exist for the rooms that need to deviate, but the defaults are tuned to feel right out of the box.
Kartofant — your Wallet passes, printable
Boarding passes, event tickets, coupons, loyalty cards — Apple Wallet is great at
holding them, less great at getting them onto paper or into a calendar. Kartofant
imports any .pkpass file straight from Wallet, Mail or Files, and turns it
into a clean, print-ready PDF or image, sized to fit your printer.
Home Screen widgets mirror the real card layout — barcode included — so the ones you need next are one glance away. Everything stays on your device: no account, no server, no tracking.
