Health numbers are hard to read on their own. They tell you what happened, but not how you’re really doing.
Coco is a quiet health coach that turns those numbers into one gentle word for you.
■ Numbers, put into kind words
On-device AI reads your sleep, heart rate, steps and activity, then says something natural like “you may be a little tired lately.” Open it each morning and quietly notice how today’s you is doing.
■ Log mood and body by voice
Log your mood, weight, water and runs with a single tap — or just say “Log my mood in Coco” to Siri. Check today at a glance from the Home Screen widget, too.
■ See how the numbers connect
“I feel good on days I sleep well.” Coco gently sums up how your mood relates to your sleep and activity, plus a weekly look back.
■ All inside this device
Every insight is generated by on-device AI (Apple Intelligence / on-device LLM). Your health data is never sent to the cloud, or to us. No ads, no tracking.
■ You can talk it over
Tell Coco what’s on your mind, and it answers with your data in view — calmly, without rushing you.
― Who it’s for ―
• You can’t quite tell what your health numbers mean
• You want your ups and downs watched over gently
• You’d rather not hand your health data to anyone
• You want logging to stay effortless
― About pricing ―
The download is free. Metrics, scores, logging, trends and the widget are free forever.
“A word from Coco,” powered by on-device AI, is free to try for 3 days; after that, Coco Plus (monthly / yearly / lifetime) makes it unlimited. Coco Plus starts with a 7-day free trial.
* “A word from Coco” works most naturally on Apple Intelligence devices. On other devices it automatically falls back to rule-based words.
Quietly notice the “you” behind the numbers.
Coco — your own health coach.
