What Kaky does

Kaky is a voice-first nutrition tracker for iPhone. Instead of searching a database or scanning barcodes, you simply describe a meal out loud, for example chicken tajine with couscous, and Kaky turns it into a calorie and macro log. The app separates the foods it heard, shows estimated calories, and lets you adjust portions before you save.

Key features

Voice and keyboard logging: speak your meals, or type them with unlimited keyboard logging when talking is not practical.
Calories and macros: Kaky tracks calories along with protein, carbs and fat.
Weight and water: record weight trends in your preferred unit and log hydration with one tap.
Progress insights: weekly patterns and direction-based feedback help you see where you are heading.

How the voice logging works

Kaky records audio only while you are actively logging, trims silence, and sends the clip securely for transcription and analysis. This keeps entry fast and low-friction.

Free and Pro

The free tier includes unlimited keyboard logging, two voice logs per 24 hours and core tracking. Kaky Pro unlocks unlimited voice logging, faster AI responses, deeper insights and higher-accuracy food intelligence, with a seven-day free trial for new subscribers.
