Question 1

Tip-percentage etiquette

Accepted Answer

In the US, 15–20% is standard for restaurants; 18% is a common default. In Europe and Asia, tipping is typically smaller (5–10%) or already included as service charge. Set a sensible default for where you are.

Question 2

From-a-photo mode

Accepted Answer

Switch to "From a photo" and upload a snapshot of the receipt. CalcWize sends the image to a vision model that reads the line items, then lets each person tap which items are theirs. The total comes out as a per-person breakdown including the optional tip. Useful when 4+ people are splitting and not everyone ate the same — the photo flow handles itemised splits even though equal-split mode doesn't.

Question 3

When tip is already included

Accepted Answer

In many countries (most of Europe, Japan, Australia, NZ), restaurants either include service in the bill or the cultural expectation is no tip at all. Tipping on top of an already-included service charge is double-paying. Always check the bill for "service charge", "couvert", "10%", or similar before adding more — and respect the local norm rather than the US default.
