Features
Colorwalk avoids feeds, scores, streaks, and performance loops. It uses a weekly color prompt, tactile stamps, handwritten postcards, and optional one-to-one exchange to make photography feel more like memory.
Find the color
A weekly prompt creates focus without pressure, encouraging the user to notice color in ordinary places.
Make a postcard
A captured photo becomes a perforated stamp, paired with a short editable message, date, and location.
Mail it onward
The user can keep a private collection or exchange one postcard with another person in the same color week.
This Week
The home view shows only the current week's color, framed as stamps. Limiting entry to seven days keeps the practice rhythmic — never the weight of the full archive at once.
All Weeks
The full collection surfaces only when asked for. Stamps stack by color, not by date. A calendar view would have made this a habit tracker.
The captured moment
Each stamp opens to a full postcard with handwritten note, location, and date. Serif handwriting and the postcard metaphor frame this as correspondence with the self.
A small fact, given softly
Postcards reveal quiet context about the color. The information is editorial, not gamified — knowledge as a gift, not a reward.
Places
Tapping a cluster opens the moments captured there. Stamps stay small and uniform — every moment kept its size, no "best" photo surfaced.
Universe
Anonymous postcards arrive from walkers in other cities. No profile, no like, no reply. The asymmetry is the entire feature.
Capture
The viewfinder is shaped as a stamp, not a rectangle. The user isn't photographing the world; they're choosing one piece of it to keep.
Writing the moment
Handwriting font and postcard layout slow the act of captioning — closer to writing yourself a letter than tagging a photo.
How it works
A tiny prompt for attention, movement, and memory.
Savoring
Finding a color gives the walk a gentle reason to notice positive stimuli already present in the day.
Attention restoration
A color to find gives the walk a soft cognitive spine: active enough to engage, loose enough to restore.
Behavioral activation
Engagement with the environment can precede mood change. Colorwalk makes that first step small and concrete.
Anonymous disclosure
Postcards are exchanged without a feed, profile, or performance loop, leaving room for low-pressure emotional support.
