Using a computer? See Lot numbers on your computer.
Every lot has a Lot Number: a whole number of 1 or more, unique within its catalog. The app fills it in for you, can read it from a sticker in your photo, and lets you change it at any time.
How the number is filled in
The Lot Number field sits below the photos when you add or edit a lot. At its right are two buttons: the sparkle fills the number, and the arrow opens a menu of ways to fill it.
| Choice | What it fills in |
|---|---|
| After last entered | The number of the lot added most recently, plus 1 |
| Next available | The lowest number no lot uses yet (it fills gaps first) |
| Next highest | The highest number in the catalog, plus 1 |
| Detect number in photo | The number on the sticker or tag in your photos |
The choice you pick is saved to your account and used on your computer too. Until you pick one, the app uses Next available. On a new lot the number is always filled in for you.
Read the number from a photo
- Put the lot's sticker or tag in the first photo, flat and in focus.
- Choose Detect number in photo from the menu.
- LotJitsu reads up to five of the lot's photos, cover first, and fills in the number.
If it can't read a number clearly, the field stays as it was and shows "Unable to detect lot number." Type the number yourself. With no photo yet, it shows "Add a photo to detect the lot number."
Change a lot's number
- Open the lot.
- Change the number in Lot Number, or use the sparkle.
- Tap Save.
When the number is already used
If you add a lot with a number another lot in the catalog uses, a screen headed Lot N already exists opens:
- Change lot number: type a different number.
- After last entered or Next available: use the number shown.
- Merge with existing lot: add your new photos to that lot and keep its details.
- Replace existing lot's images: swap that lot's photos for yours, keeping its number and details. Its old photos can't be brought back.
- Back: return to your photos to look again.
Good to know
- Only digits can be typed. A tag such as A12 can't be used.
- In Standard mode the new lot holds its number as soon as the New Lot sheet has photos. If you then change it to a used number, "Lot N already exists in this catalog" appears under the field instead of the screen above. The lot's page shows the same message.
- Two lots can't swap numbers directly. Move one to a spare number first.
- With no connection, Detect number in photo can't run, so the app uses Next available instead without telling you. Check the number before you continue.
- A lot saved with no connection can get a different number when it is sent, if someone else used its number in the meantime. See How offline changes are sent.
- The menu describes Detect number in photo as "Read it from a photo (AI)".
