GRUZ is an Android application for creating and sending personalized postcards, designed with a clear step‑by‑step workflow. The app guides users through five main stages: taking a photo, checking details, adding text, entering recipient information, and previewing the final postcard.
It supports photo capture from the camera or gallery, editing tools for adjusting images and fonts, and design options such as frames or themes. Users can enter sender and recipient addresses, write messages, and preview both the front and back of the postcard before sending. Helpful feedback messages confirm whether data is complete, saved, or if errors occur (e.g., missing address, message not ready, or no access to an image).
Additional features include registration, logs of sent postcards, and help sections. With its structured flow and creative editing options, GRUZ makes digital postcard creation intuitive and reliable.
