Miyaku — Wellness app

Product

I built Miyaku because I wanted a nutrition coach that wouldn't force me to weigh every plate or search endless databases — something that reads my day across the three pillars I care about: nutrition, hydration, and movement.

1. NutritionYou take a photo of the plate and a vision model identifies the food and calculates calories and macros instantly, with suggestions like "High in protein" or "Low in carbs." You can edit the result — name, meal type, macros — or search a catalog of about 100 common foods as an alternative to the photo. You review the history by week, with a calorie chart and the detail for each day.
2. HydrationYou log water in "glasses" of a size you choose (150 to 500 ml) — tap an empty glass and it fills, tap a full one and it empties, no plus or minus buttons. The daily goal is calculated automatically from your weight and activity level, and it's treated as a separate goal: it doesn't mix with your calorie balance.
3. MovementYou connect Apple Health once, and from there Miyaku reads steps, distance, active calories, and exercise minutes from any wearable you already have synced — Apple Watch, Garmin, Fitbit, or the iPhone itself — without integrating each device separately. You see it summarized on Home and in 7-day charts in Progress.
4. OnboardingBefore letting you into the app, it asks for your goal, your physical stats, and your activity level, and calculates your real macros with the Mifflin-St Jeor formula — no generic values from day one.
5. AI coachEvery day you get a message from the coach based on your macros — it recognizes about 12 different situations, from being short on protein to a day-end wrap-up based on how you did. Your Momentum Score is calculated over a 14-day window (50% food, 30% protein, 20% hydration): you always see the score, the written analysis is PRO only.
6. FreemiumMiyaku offers an annual PRO plan, and the price you see is always pulled live from RevenueCat — never hardcoded or stored only in the database, because Apple charges differently by country.
