Vitals & Custom Health Tracking

HealthAYF includes built-in trackers for the most commonly monitored health metrics:

Every person's doctor monitors different things. HealthAYF lets you create unlimited custom trackers — name them anything, set the unit, and log them alongside your standard vitals.

Common custom trackers families use:

• Vitamin D (25-OH): Low Vitamin D is extremely common in India — track quarterly test results to see whether supplementation is working
• TSH (Thyroid): For anyone on thyroid medication — track every 3–6 months as recommended
• HbA1c: Also available as a standard sub-metric under blood sugar — or as a standalone custom tracker
• Creatinine: Kidney function — important for long-term diabetics and anyone on certain medications
• LDL / HDL / Triglycerides: From lipid profiles every 6–12 months
• SpO₂ (oxygen saturation): Especially useful for anyone with respiratory conditions

Every metric you log in HealthAYF generates a trend chart automatically. Charts show the progression over days, weeks, or months — so you can answer the question your doctor is always implicitly asking: "Is it getting better, worse, or stable?"

• BP charts show systolic and diastolic on the same graph — you can see at a glance whether the gap between them is widening or narrowing
• Blood sugar charts show fasting and post-meal as separate lines — making it easy to identify which type of reading is out of range
• Custom trackers get their own chart — so your TSH trend is not mixed with your Vitamin D trend
• Showing a doctor the 3-month BP chart at a cardiology visit is far more useful than a single reading taken in the clinic

The most common reason a BP log is inaccurate is inconsistent technique. To get readings your doctor can trust:

• Measure at the same time each day — before morning medication, and before dinner
• Sit quietly for 5 minutes before measuring
• Keep the cuff at heart level, arm resting on a table or armrest
• Do not measure within 30 minutes of eating, coffee, or exercise
• Take two readings 1 minute apart and log the average
• Log the reading immediately — do not rely on memory, even 10 minutes later

Log what your diabetologist has specifically asked for. Common measurement times:

• Fasting: First thing in the morning, before eating or drinking anything except water — the most universally requested reading
• Post-meal (PP): Exactly 2 hours after the first bite of a meal — if your doctor has specifically requested it
• HbA1c: A lab test — not a home reading. Log the result from the lab report each time it is done (typically every 3 months)

A doctor seeing a patient every 3–6 months makes decisions largely based on the data you bring. A chart showing 90 daily BP readings is worth more than any single measurement taken in the clinic.

Before every specialist appointment:

• Generate a PDF health summary in HealthAYF — it includes all vitals with trend data for the period
• Share it with the doctor via WhatsApp before the appointment — so they can review the data before they see you
• Highlight any readings that were out of range or accompanied by symptoms
• If seeing a new specialist, the full history view shows the complete picture — not just the last 3 months
