We’ll read it.
Take a photo of a medicine box or food package, or pick one from your gallery. TraceNook reads the printed text and suggests names. If it finds an expiry date, it fills it in.

Expiry fills itself in
When an expiry date is found, it’s filled in for you. If the date is on the side or bottom, use “Scan expiry date” to take a close-up of just the date.
Text is read on your phone; photos aren’t uploaded for scanning. Unlimited scans, even on the free plan. Check the details before saving.

Even which box
it’s in.
Things you use a few times a year, like a USB-C adapter, are the easiest to lose track of. Record room › shelf › box, and you’ll know which box to open. Put a QR label on the box, and a quick scan with your phone shows what’s inside. No need to open it.

Do you have enough
emergency supplies?
Enter your household size and the app works out what you need: drinking water, emergency toilet bags and more. Then it compares that with what you’ve already added: what’s ready, what’s short and what you haven’t added yet.
- 1
Choose a guideline
Japanese government guidance (3 or 7 days) or the Tokyo Metropolitan Government’s guide. The sources are listed in the app.
- 2
Set your household size
Drinking water, for example, is worked out as 3 L per person per day × people × days. You can include pets too.

Compare with your stock
No need to add everything again. The app finds related items you’ve already added and shows how much you’re short, in liters or uses.
This shows list progress, not how safe you are.

One list for the whole family
Everyone installs TraceNook and pairs once by scanning a code on the same home Wi‑Fi. After that, changes sync whenever you open TraceNook: directly on the same Wi‑Fi, or end-to-end encrypted through a relay when you’re away. No account needed.
- Creating a family space requires Max; family members can join on any plan, including free.
- When someone restocks or uses something up and records it, everyone sees it next time they open the app.
- The family owner can back up the whole family list and restore it on a new phone.

Questions you might have
Do I have to log everything at once?
No. Add things as you go. Start with the things you don’t want to run out of, or that expire.
Is adding items a hassle?
Pick an everyday item and its name, category and unit are filled in, with a built-in product photo if you haven’t added one. Or type a sentence, use your keyboard’s voice typing, or scan a package for name and expiry suggestions. Check everything before saving.
What counts toward the free limit, and how do I get 100 slots?
You start with 50 item records in your personal space. The quantity within one record doesn’t count extra, but a separate record for a different date counts as one item; photos, places and family-space items don’t count. In Rewards, complete tasks such as adding items or photos, searching and opening a result, and creating labels, then open unlocked chests to earn up to 30 extra slots. Turning on Google Drive automatic backup adds 20 more once the first backup completes, for a total of 100. Earned slots don’t expire. At your current limit, existing items stay viewable, editable and available to back up.
Is there an iPhone version?
Yes. TraceNook is on the App Store for iPhone and on Google Play for Android, free to download.
Can my family use it together?
Yes. Creating a family space requires Max; family members can join on any plan. Pair once on your home Wi‑Fi, and changes sync whenever you open TraceNook at home.
Does it need the internet? Where is my data?
Adding and searching work offline. Your data stays on your own devices. When family phones aren’t on the same Wi‑Fi, changes travel end-to-end encrypted through our relay, which can’t read them and deletes them once delivered.
What if I change phones?
Export an encrypted backup file and restore it on your new phone.
Can I organize on a computer?
Yes. With your phone and computer on the same Wi‑Fi, open it in your computer's browser to edit in bulk, print QR labels and export your list—no software to install.
Which languages?
English, Chinese and Japanese.
