One photo a day becomes one color, and your year becomes a grid of them. No account, no streaks, no subscription. Your photos stay on your phone.
Take one photo a day and pick the color it gives you. By December your year is a grid of colors you can read at a glance.
Chroma is a diary without words. You do not write, you look: at the sky on the way to work, the coat of the person ahead of you in the queue, the light in the kitchen. The app finds the colors in your photo, and you choose the one that was your day.
PICK THE COLOR, NOT A FILTER
Chroma offers up to five colors from each photo, the most vivid always among them, and every color has a name: storm blue, sage, terracotta. You can change your pick all day long, and add one word if the day asks for it.
A YEAR IN ONE LOOK
My year shows every day as a square, twelve months side by side. Switch to the strip and the year becomes one long gradient, from winter greys to summer ochres. Tap any day to see its card and its photo.
A CARD WORTH SHARING
Every day makes a card: the color edge to edge, its name, the date and your photo in a corner. Share it with the photo, or with the color only when the photo is just for you.
ON YOUR HOME SCREEN
The today widget is your color, edge to edge, with its name. Never your photo: the home screen is seen by whoever is next to you.
ONE REMINDER, AND IT KNOWS WHEN TO STOP
A single daily nudge at the time you choose, asking what color today is. It stays quiet once today has its color.
EVERYTHING STAYS ON YOUR PHONE
No account, no sign-up, no cloud of ours. Photos are stored without their location. Export all your days, photos included, as one file whenever you like, and import it on another phone: importing adds, it never deletes.
FREE, WITHOUT A TIMER RUNNING
Photos and colors, My year, sharing cards, the reminder, the today widget, and exporting and importing your data: all free, permanently.
PRO, ONE PAYMENT
The year poster, in three styles to print or to use as a wallpaper, and the year widget. One payment, once, never a subscription.
WHAT YOU WILL NOT FIND HERE
No streaks, no filters, no likes, no ads, no analytics.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- My year fits on one screen: the whole year at a glance, no scrolling.
- Hold a color to see its name before you pick it.
- Share sits right under your card, and the photo only goes along if you include it.
- On shorter screens, Today's buttons show without scrolling.
- Better with a screen reader and with reduced motion.
