some things take time to feel.
develop. is a quiet daily record of how you actually felt.
take one photo a day. tag the mood. it develops overnight and reveals the next morning at 7am, the way a roll of film used to come back from the lab. no feed to scroll, no likes to chase. just an honest picture of your days.
how it works
· one photo, once a day.
· choose from eight emotion families, then the exact word for it.
· add a private note if you want to say more. it is yours alone.
· the photo develops overnight and reveals at 7am.
look back
· your month and your year, drawn as maps of colour. one shade per mood.
· tap any day to reopen that photo and its note.
· your whole history, free.
· save any of it as a clean image to keep or share.
see your patterns
· mood insights show what you have mostly felt, how often you showed up, and your most-used word, by month or by year.
a gentler community, if you want it
· post a photo anonymously to a global feed, or keep everything private.
· it is off unless you choose it, every single time.
· no names, no profiles, no follower counts, no comments and likes.
develop+
· remove ads.
· unlock your full mood insights, month and year.
· $1.99 / month.
develop. is for anyone who wants to notice their life a little more honestly, one photo at a time.

Ratings & Reviews

your month is now a colour map, the same way your year already was. simpler to look back on, and to share.
new in this version:
· add a private note the moment you take your photo. just for you, never shared.
· tap any day in your month or year to open that photo.
· front camera, so your daily photo can be a selfie.
· insights now cover the whole year, not just the month.
· swipe through the community feed instead of opening one photo at a time.
· a clearer way to post to the community. always anonymous, always your choice.
plus quiet fixes and polish throughout.
