take one photo a day, tag how you felt, and let it develop overnight. your week, month, and year of feelings, in colour.
some things take time to feel.
develop. is a daily photo journal that works like film. each day you take one photo and tag how you felt. it locks overnight and reveals the next morning at 7am, so you never judge a moment in the instant you live it.
over time, your days become something to look back on:
· a weekly film strip of seven feelings
· a monthly roll
· your whole year, every day a colour, in one grid
how it works:
· shoot one photo a day
· choose a feeling, then the word that fits best
· wait for it to develop overnight
· reveal it at 7am and keep it in your journal
mood insights:
see your month in feelings. your patterns, how consistently you showed up, and the words you reach for most.
a quiet community:
share a photo anonymously if you want to, or keep everything to yourself. sharing is always off by default.
