提出物OK is an iPhone app designed for easy submission tracking using QR codes. Users can create custom QR codes for different submissions like contact lists or notes, with each code numbered for easy identification. When scanning a submission, the app plays a selected sound effect, offering a fun touch to the process.

The app allows quick verification of submission statuses per item, showing at a glance which submissions are pending. With support for up to 50 individuals, users can efficiently manage class sizes. Its simple design enables straightforward scanning and result checking, with the added benefit of a dark mode for user preference.
