Read full descriptionHide full description
See how much time is left at a glance. Color Timer is a visual timer with a full screen countdown. As time passes, the colored area shrinks, giving you a clear sense of the time remaining. Set it on your desk for a study session, glance over while cooking, or keep your next presentation on time. A clear screen for your countdown Large numbers and vivid color fill the timer screen. There are no ads on the countdown screen and no full screen ads to wait through before starting. Keep the timer open and your screen stays awake while the countdown runs. Save it once. Start with one tap. Save your favorite timers with a name, duration and color, then start them directly from the home screen. Choose 1, 5, 10 or 25 minutes with quick duration buttons, reuse a recent duration, or set your own hours, minutes and seconds. Big numbers, in portrait or landscape Use your phone or tablet upright on your desk or sideways for a meeting, presentation or class. Choose from 18 color themes. Turn on the finishing-soon cue for a change in color and an on-screen message as time runs low. Pause, adjust and keep going Pause and resume, add a minute, or restart when you need to. Lock the controls to avoid accidental taps. Adding a minute to a running countdown leaves your saved timer's duration unchanged. Choose how your timer ends Preview and choose from 8 built-in alarm sounds. Switch sound and vibration on or off separately. In a quiet space, turn both off and use the visual display. Time for everyday moments ⢠Study and work: set aside time for one task. ⢠Cooking and tea: check the time with a quick glance while your hands are busy. ⢠Presentations, meetings and classes: share an easy-to-see countdown. ⢠Stretching and breaks: make room for a few minutes away from your desk. For a simple Pomodoro routine, start a 25-minute focus timer, then start a 5-minute timer for your break. No account is needed. The timer itself works offline. The app interface follows your device language, with Korean and English supported. Ads appear only on the home screen. Allow notifications to receive an end-of-timer alert while the app is in the background. Sounds and vibration depend on device capabilities and system settings.

PREMIUM ā PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Tap once. A random color fills the screen ā named, coded, and ready to copy as HEX, RGB, or HSL. ColorRandom is a random color generator for people who need a color right now: no boards, no sign-up screens between you and the color, just a fresh specimen on every tap and a one-tap copy of its code. Most random color apps roll the dice the same way every time. ColorRandom gives you eight documented sampling modes ā and tells you exactly how each one works. Pastel, Vivid, Muted, Deep, Warm, and Cool sample specific regions of color space; Spread steps the hue by the golden ratio so consecutive colors stay far apart; Any is uniform over the whole RGB cube. Every color is also named perceptually in CIELAB, so the label you read matches what the rest of the world calls that color. WHAT YOU GET ⢠A full-screen color on every tap, with its everyday name ā Cobalt Blue, Peach, Sea Green ā matched by perceptual distance, not guesswork ⢠HEX, RGB, and HSL side by side, each copied to your clipboard in a single tap ⢠Eight sampling modes, from soft pastels to deep near-blacks, including a golden-ratio Spread mode that keeps back-to-back colors from looking alike ⢠A WCAG 2.1 contrast readout under every color: the exact ratio against white and against black, graded AA or AAA before you put text on it ⢠A bookmark archive of the colors worth keeping ā tap any saved specimen to bring it back full screen ⢠Palette export as a hex list, CSS variables, ready-to-paste SwiftUI code, JSON, or a printable PNG sheet PERFECT FOR ⢠Developers who need a color code in the next ten seconds, not a design meeting ⢠Designers shaking off a stale mood board with genuinely random inspiration ⢠Students seeing how hue, saturation, and lightness map onto hex and RGB values ⢠Anyone who color-codes calendars, spreadsheets, teams, or cables and is tired of choosing WHY NOT JUST A PALETTE WEBSITE? Palette sites hand you five-color schemes someone else curated, behind a browser tab and a login prompt. ColorRandom gives you one honest random color at a time, with its codes and its contrast math, entirely on your phone. When surprise is the point, curation is the enemy. PRIVATE BY DEFAULT Everything runs on your iPhone. No account, no tracking, no analytics on your taps. Your saved colors are stored on-device and never leave it. PREMIUM (PURCHASE REQUIRED) ColorRandom Pro unlocks the unlimited color archive and every export format ā hex list, CSS, SwiftUI, JSON, and the PNG palette sheet. Choose the weekly or yearly subscription, or make a one-time lifetime purchase. Tap the swatch. The next color is already waiting.
