Mini Chroma Clock
Read full descriptionHide full description
ChromaClock — a color‑coded clock for the rhythm of your day. ChromaClock turns the time on your phone into something you can feel at a glance. Instead of just numbers, the entire screen shifts color throughout the day based on time windows you define — morning yellow, lunchtime green, afternoon blue, evening red, or whatever fits your life. It's a beautifully simple bedside clock, desk companion, kitchen timer reference, and gentle daily rhythm — all in one. HOW IT WORKS • Set up to four time slots, each with a custom start time, end time, message, and background color. • When the clock enters a slot, the background and greeting change automatically. • Outside of any scheduled slot, a default "in‑between" color takes over. • That's it — no accounts, no setup beyond your slots. WHAT YOU SEE • Big, easy‑to‑read time in a rounded display • The full date — day of the week, month, day, year • A friendly greeting you write yourself ("Good Morning", "Time to focus", "Wind down") • Current weather for your location, right in the corner WEATHER, WITHOUT THE FUSS Tap the weather chip to see live conditions and temperature for where you are. Tap again to refresh. Weather data comes from the free, open Open‑Meteo service — no accounts, no tracking, just the forecast. PERFECT FOR • A bedside clock that signals morning vs. late evening at a glance • A desk clock that reminds you when it's lunchtime or time to log off • A kitchen or family clock with messages everyone in the house can read across the room • Kids learning the rhythm of a school day, before they can read a clock • Anyone who wants a calmer, more colorful way to keep time THOUGHTFULLY MADE • Built entirely in modern SwiftUI for iOS • Big, accessible type with high‑contrast color backgrounds • Landscape support — great when propped on a stand or dock • Dark, screen‑friendly design • No ads. No tracking. No accounts. Your settings stay on your device. Set it once, prop it up, and let your day take on a little color.

Cool Penguin Clock's advantage is update cadence (every 3 weeks vs every 54 months) and iOS requirement (12.0 vs 26.0). On price and device support there is nothing between them.
