About oyster omelette (orh luak)

Orh luak is the hawker oyster omelette: a sweet potato starch batter set in a hot wok, broken up with beaten eggs, then folded with small plump oysters and served with chilli-lime sauce. The crisp edges and chewy starch both mean oil, which is where most of its calories come from.

In PlateDiary

A rough number for the dishes you save — only if you want one.

Off unless you turn them on

Calories in PlateDiary are off unless you turn them on. Switch them on and, when PlateDiary AI reads your photo of the table, each dish gets one rough “~” number. Accept it or change it; a number you correct is remembered for that dish. With Calories off, the app looks exactly as it did before.

A read sends small pictures of the cut-out dishes, with the place's name as a hint — never the table photo, faces or your location. Calorie numbers never go to analytics, and nothing is written to a health app. PlateDiary AI starts with free tries; here is how it works.
