1. Finish the walk or the feeding. Scanning is always something you do afterwards.
2. Hold your phone to the sticker. On iPhone, hold the top edge of the phone near the sticker with the screen on. A banner appears — tap it.
3. Confirm. The app opens and asks you to confirm. Nothing is saved until you tap the confirm button.
What a scan means
A scan records that someone reported the task as done. It is not proof that the walk or feeding physically happened. Sticker links can also be copied, so entries are labelled "Sticker link" rather than "verified scan".
