If the appetite is still there
Two ways to take the edge off
Photos you'd rather not seeWhen fried chicken comes to mind, you deliberately face a gross image. It's meant to put a brief brake on the urge. It works for some people more than others, and if you'd rather not see them you can turn them off for SOS in Settings.
Food that turns blueBlue Lens works from the other side. Point your camera at the pizza in front of you and the same food turns blue. Blue may help curb appetite.

Frequently asked questions
- What is fake hunger?
- It's the urge to eat that comes from stress, boredom or habit rather than an empty stomach. Kontrol's Fake Hunger Test asks a few quick questions to help you see which one you're feeling right now.
- What kind of diet app is it?
- It doesn't count calories or log meals. It's for the moment a craving hits β it gives your hands and head something else to do until the urge passes, and it works alongside any tracker you already use.
- How is it different from just holding out?
- Instead of white-knuckling it, you shift your attention elsewhere for a while. Many cravings fade within about 20 minutes, so the goal is to get through that stretch.
- What are the gross images for?
- They show the opposite of the food you're craving, to put a brief brake on the urge. How well it works varies from person to person, and you can turn them off for SOS in Settings.
- What does Premium add?
