About

I built Health for myself. I wanted one place to keep an eye on the things I actually care about following day to day, without juggling several apps or handing my data to a dozen different services. It does what I need today, and I add new functionality over time as my own needs grow. If something feels focused and to-the-point rather than bloated, that is on purpose.

Health brings together five things in a single, easy-to-read app:

• Food & calories — log what you eat by scanning a barcode, searching a food database, or adding your own custom foods.
• Daily goal — see your net calories against a daily target, plus your protein, carbs, and fat at a glance.
• Activity — record workouts (including live heart-rate sessions) and pull in your steps and walking distance.
• Weight — track your weight over time with a trend chart.
• Blood pressure — log readings, see how they fall into standard categories, and review your averages.

Everything is organized around a day view: pick any date, and the app shows your food, activity, and health metrics for that day.

Feature tour

Food & calorie logging

• Scan a barcode — point your camera at a product and Health looks it up automatically.
• Search a food database — search by name when you do not have the package handy. Food data is sourced from the public Open Food Facts database.
• Add custom foods — create your own entries for home-cooked meals or anything not in the database, and reuse them later.
• Adjust servings — set the serving size and the calories and macros update instantly before you add it to your log.
• Edit or remove entries — tap any logged item to change it, or swipe/long-press to delete.

Daily goal ring

The goal ring is the heart of the home screen. It shows your net calories (what you ate minus what you burned) against your daily goal, with your protein, carbs, and fat beside it. You can set a goal manually, or let the app calculate a maintenance estimate from your body stats (using the well-known Mifflin-St Jeor formula) and use that as your goal.

Daily summary

A compact summary card gives you the day at a glance: calories eaten, calories burned, steps, distance, and - when available - your latest weight and blood pressure for that day.

Body stats & maintenance calories

Enter your sex, age, height, weight, activity level, and (optionally) resting heart rate. Health estimates how many calories you need per day to maintain your current weight, and can turn that estimate into your daily goal with one tap.

Exercise & heart-rate workouts

• Log workouts with duration and estimated calories burned.
• Connect a Polar heart-rate monitor to run a live workout session, with calorie estimates based on your heart rate.

Walking & steps

Health reads your steps and walking distance from Health Connect, so anything that syncs there (for example Samsung Health) shows up automatically. It can also estimate the calories from walking and optionally fold them into your daily burn.

Weight tracking

• Add weigh-ins manually, or sync them from Health Connect (for example from a Withings scale).
• See your progress on a trend chart.
• The body-stats weight field stays in sync with your most recent weigh-in.
• Long-press any entry to delete it.

Blood pressure

• Log readings manually or sync them from Health Connect.
• Each reading is color-coded by standard American Heart Association categories.
• Group readings by time of day (morning, afternoon, evening) with adjustable boundaries, so you can see patterns.
• Review weekly and monthly averages for each time period, with a built-in explanation of how the averages are calculated.
• Long-press any entry to delete it.

History & calorie deficit

A tabbed History screen lets you scroll back through your food, exercise, walking, blood pressure, and weight records. It also includes a calorie deficit view that compares the calories you took in against your sedentary maintenance plus your logged activity, and relates that to your expected and actual weight change over the week.

Make it yours

• Collapse any card you do not need front-and-center.
• Drag and drop to reorder the cards on the home screen.
• Light and dark mode follow your system setting automatically.

Backup & restore

Your data lives on your device. Health includes a one-tap export that saves everything - food, exercise, walking, weight, blood pressure, custom foods, and settings - to a single file, and an import to restore it. This is handy when moving to a new phone or before reinstalling.

Getting started

1. Set your body stats. Open Body stats (the person icon) and fill in your details to get a maintenance calorie estimate, then optionally set it as your daily goal.
2. Log your first food. Scan a barcode or search for a food, adjust the serving, and add it to your day.
3. Connect Health Connect (optional). On the Walking card, connect Health Connect to pull in steps and distance from your phone or wearable. Weight and blood pressure can sync the same way.
4. Add a workout (optional). Log exercise manually, or connect a Polar monitor for a live heart-rate session.
5. Check in over time. Use the History screen and the weight and blood-pressure trends to see how things are trending.

Your data & privacy

• Health is local-first: your logs are stored on your device.
• Health Connect access is read-only for the metrics you choose (steps, distance, weight, blood pressure), and only with your permission.
• Food lookups query the public Open Food Facts service by barcode or search term.
• You stay in control with built-in export and import, so your data is yours to keep and move.

Availability

Health is an Android app. The activity, weight, and blood-pressure sync features rely on Health Connect, which is available on Android.
