Build Habits while your reveal photos. Habit Developer helps reinforce your daily routines with a small reward. As you complete each task, a stunning photo gradually emerges. Whether you choose artwork by famous artists, photos of space from NASA, or your own photos, each photos is developed one habit at a time, like a darkroom print coming to life. The app is built upon real habit research with each habit having three components: cues, tasks, rewards. Cues Tie each habit to something you already do. The idea is that over time the habit sticks on its own and you won't need the app. Tasks Break each habit into small steps to make starting a little easier. Rewards Choose from NASA's Astronomy Picture of the Day, Wikimedia's Photo of the Day, Cleveland Museum of Art paintings, Pexels curated photography, or your own camera roll albums. A new image and fresh motivation every day.
