Navigating the App
HealthCare has five tabs at the bottom of the screen. Tap any icon to switch between sections.

Edit the name if you like (it will say "HealthCare") then tap "Add".
The app icon appears on your home screen. Tap it to launch.
🤖 Android (Chrome)
Open Chrome and navigate to the app URL.
Chrome may show a banner at the bottom: "Add HealthCare to Home screen" — tap it. If not, continue to step 3.
Tap the three-dot menu ⋮ in the top-right corner.
Tap "Add to Home screen" and confirm.
The app icon appears on your home screen. Tap it to launch.
Dashboard
The Dashboard is your daily health overview. It updates automatically every time you log new data.
Your latest weight with trend vs previous reading. Shows your BMI if height is set in Profile.
Latest BP reading with colour-coded health status (Normal, Elevated, High Stage 1/2, Crisis).
Today's step count vs your daily goal. The goal uses your Profile setting or defaults to 10,000.
Progress bars for each active goal — weight, steps, calories, blood pressure. Visible once goals are set in Profile.
Personalised wellness tips based on your data vs goals — weight trends, BP advice, activity suggestions.
Summary of your progress over the recorded period — weight change, average steps, BP trend.
Logging a Health Entry
Tap the Log tab (➕) to record your health measurements. You don't need to fill in every field — just record what you have.
What you can record
- Date & Time — defaults to right now. Tap "Set to Now" or adjust manually.
- Weight (kg), Body Fat %, Muscle Mass % — use the +/− buttons to fine-tune values
- Blood Pressure — Systolic, Diastolic (mmHg) and Pulse (bpm). Toggle the switch to include or exclude BP from the entry.
- Steps — your step count for the day
- Calories Ingested — total food intake in kcal
- Notes — any free-text observation (e.g. "after walking", "fasting measurement")
Editing or deleting a record
Go to the History tab. Each record has an edit ✏️ and delete 🗑️ button in the top-right corner of the card. Tap edit to load the record back into the Log form for changes.
History Logs
The History tab shows all your recorded entries grouped by date, newest first.
Filtering
Use the dropdown at the top to filter by metric:
- All Metrics — shows every entry
- Has Weight — only entries with a weight measurement
- Has Blood Pressure — only entries with BP readings
- Has Steps — only entries with step count
Sharing a record
Each record has a share 🔗 button. Tapping it opens your phone's share sheet so you can send the reading via WhatsApp, iMessage, email, or any app.
Health Trends (Charts)
The Trends tab shows your data as charts over time. Tap the buttons at the top to switch between chart types.
⚖️ Weight & Body Composition
Line chart showing weight (kg) on the left axis and Body Fat % / Muscle Mass % on the right axis. Gaps are spanned when a field wasn't recorded on a given entry.
❤️ BP & Pulse
Line chart with Systolic and Diastolic pressure (mmHg) on the left axis and Pulse (bpm) on the right axis.
👣 Steps
Bar chart showing maximum steps recorded per day (if you log steps multiple times in a day, the highest value is used).
🍽️ Calories
Bars show calories ingested (food). The line shows estimated calories burned (BMR + steps activity). The gap between the two indicates your daily energy surplus or deficit.
Profile & Goals
Personal Data
Setting up your personal data unlocks more accurate health calculations:
- Name — personalises the dashboard greeting
- Date of Birth — used to calculate your age for BMR
- Height (cm) — required for BMI calculation
- Biological Sex — used in the Mifflin-St Jeor BMR formula
- Activity Level — used to calculate your TDEE (daily energy need)
After saving, the Health Metrics card appears showing your current BMI, BMR, and TDEE based on your latest weight entry.
Health Metrics explained
| Metric | What it means | Normal range |
|---|---|---|
| BMI | Body Mass Index — weight relative to height | 18.5–24.9 |
| BMR | Calories your body burns at complete rest per day | Varies by person |
| TDEE | Total daily calories needed based on your activity level | Varies by person |
Setting Goals
Fill in any combination of goals in the Goals section and tap Save Goals:
- Target Weight (kg) — the dashboard shows progress and estimated time to reach it
- Daily Steps Goal — replaces the default 10,000 steps on the dashboard
- Daily Calorie Limit — shown as a progress bar; alerts when exceeded
- BP Target — sets a personal blood pressure reference on the dashboard
Understanding Blood Pressure Readings
HealthCare uses American Heart Association (AHA) guidelines to classify your readings:
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | < 120 | < 80 mmHg |
| Elevated | 120–129 | < 80 mmHg |
| High — Stage 1 | 130–139 | 80–89 mmHg |
| High — Stage 2 | ≥ 140 | ≥ 90 mmHg |
| Hypertensive Crisis | > 180 | > 120 mmHg |
PIN Security
Protect your health data with a 4-digit PIN. The app will ask for your PIN every time it opens.
Setting up a PIN
Go to the Profile tab and scroll down to PIN Protection.
Tap "Enable PIN Lock".
A full-screen keypad appears. Enter your chosen 4-digit PIN.
Enter the same PIN again to confirm.
A "PIN set!" confirmation appears. The app is now protected.
Auto-lock
If you switch to another app or lock your phone for more than 5 minutes, HealthCare will ask for your PIN again when you return.
Forgot your PIN?
After 3 incorrect attempts, a "Forgot?" button appears. Tapping it and confirming will erase all data and remove the PIN — this is the only way to reset it. Export a backup first if possible (see Backup section).
Sharing Health Data
You can share individual records or a full summary with a doctor, family member, or carer.
Share a single record
In the History tab, tap the share icon 🔗 on any record. Your phone's share sheet opens — choose WhatsApp, iMessage, email, or any other app.
Share a summary
On the Dashboard, tap the share icon in the "Weekly Highlights" header. This shares a text summary covering weight trend, latest BP, and average steps.
Backup & Restore
Your data lives only on your device. Export a backup regularly to avoid losing your records if the browser data is cleared or the device is replaced.
Export (backup)
Go to Profile tab → scroll to Backup & Data Management.
Tap Export JSON to download a full backup file, or Export CSV to open in a spreadsheet.
Save the file to your cloud storage, email it to yourself, or keep it in your Files app.
Import (restore)
Go to Profile tab → Backup & Data Management.
Tap Import Backup (JSON) and select your saved backup file.
All records are replaced with the imported data. A confirmation message appears.
Smart Camera Scanner (Beta)
The camera scanner can read numbers from a photo of your scale, blood pressure monitor, or handwritten notes — so you don't have to type them manually.
In the Log tab, tap "Snap Photo & Scan" at the top.
Take a clear, well-lit photo of the display or numbers you want to capture.
Wait for the scan to complete (progress bar shows status).
Detected numbers appear as chips. Tap a number to select it.
Tap the field button (Weight, Sys, Steps, etc.) to assign the value.
Review the assigned values and tap Save Record.
App Updates
When a new version is available, a blue banner appears at the top of the screen:
Tap "Update now" to install the latest version. The app will reload automatically — your data is not affected.
Frequently Asked Questions
Is my data sent anywhere?
No. All data is stored locally on your device in the browser's storage. Nothing is sent to any server. Your health information never leaves your phone.
What happens if I clear my browser data?
All health records and profile data will be deleted. Always export a JSON backup first (Profile → Backup & Data Management → Export JSON) to avoid losing your data.
Can I use the app on multiple devices?
Each device has its own data. To move data to a new device: export JSON on the old device → install the app on the new device → import the JSON backup.
Why does the app only work on mobile?
HealthCare is designed and optimised exclusively for smartphone use. Accessing it from a desktop browser will show a block screen by design.
Does the app work without internet?
Yes — once installed, HealthCare works completely offline. All your data is stored on your device and all features are available without a network connection (except the initial font and chart library download).
The charts are empty — why?
Charts need at least one logged entry to display. Log your first health record using the Log tab (➕), then navigate to Trends.
Can I log data retrospectively?
Yes — in the Log form, change the Date & Time field to any past date and time before saving. The history will order entries correctly by date.
