Add
Snap a photo or pick one from the gallery; it is compressed into a thumbnail automatically. Fill in name, quantity, unit and notes in one pass.
Know where it is. Use it in time.
Trace is a native HarmonyOS app built around one loop — item → place / category → batch expiry → reminder. It keeps your home in order: toss what is expired, use what is about to be.
Expiring items at a glance
- Native HarmonyOS app (ArkTS / ArkUI)
- Immersive interface with dark mode
- Tap-to-share across devices
- Full backup and restore
How it works
Four steps, fewer things to forget
No new habits to learn: snap a photo, say where it lives and when it expires — Trace takes it from there.
Organize
File items under hierarchical places and categories. Place cards collapse, expand and reorder by drag, so finding something is no longer a rummage.
Date
Track quantities and expiry dates batch by batch — two packs of milk each expire on their own schedule.
Remind
Items nearing expiry are flagged and pushed as notifications, and can be written to your system calendar so everything is managed in one place.
Items
A list that reads well, and actions that feel right
Switch between All, Name, Expiry and Advanced views at any time. Advanced filters combine category, place, expiry status and favourites. Long-press for multi-select to move, recategorise or delete in bulk; swipe left for quick actions.
- Four sort and filter views: All / Name / Expiry / Advanced
- Long-press to multi-select, then move, recategorise or delete in bulk
- Swipe left for quick actions, with a confirmation before deleting
- Favourite and pin, so the things you use most stay at the top
Places & categories
Hierarchical places: if you found it, you found it
Places nest two levels deep — a coffee table drawer inside the living room, a top shelf inside the storeroom. Cards collapse, expand and reorder by drag, and the places page supports long-press multi-select plus search by name.
- Two-level place hierarchy with collapsible, drag-sortable cards
- Ready-made categories, or add your own names and icons
- Units, reminder lead times and icons are all maintained in-app
- Every item shows its full path: category · place · sub-place
Batch expiry
Same product, batches counted separately
Bought three boxes of the same medicine on different dates? Give each its own batch with its own quantity and expiry date. Totals add up across batches, and near-expiry is judged batch by batch.
- Record the opened-on date and see the opened state at a glance
- Set reminder lead time per item from several presets
- A global default expiry threshold, overridable per item
- Expiry reminders can be written to the system calendar, managed in one place
Expiry
The expiry check centre
Bring expired and nearly-due items onto one page: totals at a glance, sorted by days remaining, handled item by item or with a single notification — no more digging through hundreds of rows.
- Four totals: expired / expiring soon / in good shape / total
- Sorted by days to expiry, marked off item by item
- Send reminder notifications to the relevant items in one tap
- Proxy reminders notify you on time without opening the app
Highlights
More than a notes app
Statistics, sharing, backup and grip adaptation — the details you actually run into every day.
Statistics
Total items, total stock, and counts by place and category at a glance; expiry distribution plus top-5 rankings by category and place, so you can see what you have piled up.
Tap to share
Send item data to someone else over Share Kit with a tap; the receiver previews and confirms before importing. Quality, item count and package size limits are all configurable.
Backup & migration
Full backup export and import, compatible with legacy JSON backups, and integrated with the system backup and restore mechanism.
Smart grip
Detects which hand you are holding the phone in, so the floating button and the bottom capsule dock move to the thumb side; unsupported devices degrade gracefully.
Immersive interface
Edge-to-edge status bar, a floating capsule dock for bottom navigation, and full dark mode support.
Privacy by design
Data stays on your device by default, with AGC-hosted privacy consent, a standardised privacy dialog and permission management; agreements and policies are always available.

Compatibility
Requirements
Trace is a HarmonyOS app for phones. Here is what you need to install and use it.
System
A HarmonyOS 5.0+ device (physical or emulator). Published on AppGallery, with in-app update checks.
Permissions
Camera, calendar and photo permissions are requested only when you first enable calendar reminders, take a photo or pick from the gallery, and can be revoked in settings at any time.
Data storage
Items, places, categories and photos are stored locally on the device and never uploaded; backup files are yours to keep.
Account
Signing in with a Huawei Account is optional and only used to submit feedback; every local feature works without it.
Note: the screenshots on this page are real captures from the app; item names and photos are demo content. The app contains no personalised recommendations, ads or third-party commercial SDKs.
Start today: know where everything in your home is
Ten minutes to add the dozen things you use most — Trace takes it from there. Existing data can be migrated in one backup.
