Glimmer: Private Health Coach

A health coach that never phones home.

Glimmer runs its AI coach entirely on your iPhone. Your meals, your workouts, your weight — processed on-device, stored on-device. Nothing about your body ever leaves your phone.

TALK TO YOUR COACH LIKE A PERSON

Tell it "roast chicken quarter and a beer" and it logs the calories, protein, carbs and fat. No searching a database. No scanning barcodes. No tapping through six screens to add a snack. Just say what you ate.

The parsing happens on your device using Apple Intelligence. Your food diary is never uploaded, never analysed on a server, and never used to train anything.

YOUR DAY AT A GLANCE

Calories and steps as rings you can read in a second. Protein as a bar. Weight as a seven-day trend that smooths out the daily noise. Recent workouts pulled straight from Apple Health.

STREAKS THAT REWARD SHOWING UP

Separate streaks for checking in, hitting your steps, hitting your protein, and getting your workouts done. Miss one day a week and your streak survives — because life happens, and a broken streak is a terrible reason to quit. Badges you earn stay yours even if a streak resets.

TRACK DRINKS WITHOUT THE LECTURE

Log alcohol alongside everything else and watch an alcohol-free streak build. No judgement. Just the number.

HISTORY THAT MEANS SOMETHING

Seven days of calorie history, each day scored against your goal, so you see the pattern instead of just today's total.

BUILT SO WE CAN'T SEE YOUR DATA — NOT JUST SO WE WON'T

• On-device AI, always. Meal parsing uses Apple's on-device model. • No network required. Glimmer works in airplane mode. • No account. No sign-up, no email, no password. • Delete means delete. Uninstall the app and the data is gone.

We don't sell your data because we never receive it.

WORKS WITH APPLE HEALTH

Reads your steps and workouts. Writes the meals you log back to Health, so your nutrition sits alongside the rest of your data.

Free to download. No ads.

The AI coach requires a device that supports Apple Intelligence. On other devices the dashboard, goals, streaks, history and Apple Health integration all work as normal.
