📝 About this app
The Gudak Cam has been designed to focus on long-term memory, reminiscence. It is recalling the images you took 72 hours later, when 80% of your memory has blurred and faded away, will turn your short-term memory into long-term memory. Our team also has attempted to reproduce the in-the-moment experience of taking photos by eliminating the Instant Review feature found on conventional digital cameras and reducing 95 % of the conventional viewfinder feature, leaving only the bare minimum needed for taking shots.
"Gudak-dari Camera", as its name suggests, refers to a time-worn and antique camera. Living in a digital generation where "Un-do" function is prevalent, we may have lost
the thrill of making new and conscious decisions. "Patients is a virtue" has faded its original value and people are getting used to selecting one palatable photo out of a myriad of photos. Amid this so-called "digitalization", we hope you to recall the thrill of making new choices by seizing the "Gudak Moment".
Gudak 3.2 Update has added a self-camera feature that allows you to shoot with a front camera as Gudak feels.
Experience a new look of Gudak and a variety of emotional photos with front cameras as well as rear cameras. The theme will be updated further in the future.
*The Lecoq film is only available in Korea.
Also, for those who feel that Gudak photos are dark, you can adjust the brightness of photos through the newly added ISO (based on world standard film sensitivity).
A Gudakbook icon has been added to make Gudak photos a real album. Try to experience the feeling of those days through Gudakbook like the excitement I felt when printing the film camera. You can apply for Gudakbook through the print icon on the Printed Envelope Check page.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
