About this app

This is an app for pasting barcode labels on school submissions and checking them. After pasting a barcode sticker on a homework notebook and instructing students to scan the barcode before submitting, checking their submissions is now completed in an instant. You can use it without entering any personal information. No ads. Completely free. Barcode samples can be mailed. See support URL.


This is an app for pasting barcode labels on school submissions and checking them. I used to spend time checking my homework every day. I would count the number of submissions, and if there were not enough, I would ask, ``Who hasn't submitted?'' When I didn't know who hadn't submitted, I was wasting my time.

However, after I pasted a barcode sticker on my homework notebook and instructed them to scan the barcode before submitting it, I was able to check their submissions in an instant.

Teachers don't have to look for unsubmitted students, and students find it interesting to scan barcodes and submit them themselves, so it's a win-win.

At first, I used a barcode scanner and spreadsheet software connected to a PC and USB to check. Even with that system, I was able to improve efficiency considerably and was satisfied, but I suddenly thought that if there was an app that could scan and check barcodes on iPhones and iPads, it would be possible to reduce the workload of Japanese teachers. , created this app.

The app targets iPhone 5s and later. The reason is that you can get a used iPhone 5s at a very low price. At least it's cheaper than buying a PC, spreadsheet software, and USB scanner.

Read the JAN abbreviated 8-digit barcode. This app assumes 4 types of submissions and a maximum class size of 40 people, and is intended to be used as a set with 4 x 40 = 160 barcodes.

Please refer to the support URL and marketing URL for barcode samples. (Under construction as of 2019/09/14)

I think it would work if you printed the barcode sample on A4 paper and pasted it with glue, but it's much easier to use label paper. We are preparing to send label paper with barcodes printed on it free of charge to those who request it.

Please note that no personal information remains in this app. The information handled within the app is a 7-digit integer and does not contain personally identifiable information.

We would be happy if we could reduce the workload of elementary, middle school, and high school teachers who handle their demanding daily tasks.
