What is Health Box?
Health Box is Toolsda's set of standards-based wellness calculators — the kind of quick check you'd otherwise search for one at a time. Every tool cites the standard it's built on (WHO, AHA, NCEP ATP III, or a comparable published guideline) and is informational only, not a substitute for a doctor.
The 7 tools
- Pregnancy Due Date Calculator — Track due date + week by week baby growth with Indian fruits - free, private.
- BMI Calculator — BMI, BMR, and ideal weight calculator.
- BP Checker — Check if your blood pressure reading is normal.
- Cholesterol Calculator — Lipid Profile Interpreter - HDL LDL explained in Hindi + English.
- Fever Checker — Check your body temperature against normal ranges.
- Period Calculator — Next period, ovulation, and fertile window - private, no login.
- Water Intake Calculator — Your daily water target by weight, activity, climate and pregnancy.
Why on-device matters here
Weight, blood pressure, lipid panel results, and cycle dates are sensitive by nature. Every calculator in this box runs its math locally in your browser — there's no account, no server log, and nothing to breach, because nothing you type ever leaves your device.
Frequently Asked Questions
Are these health calculators a substitute for medical advice?
No — every tool here is informational only, based on published standards like WHO and AHA guidelines. They're a starting point for a conversation with a doctor, not a diagnosis.
Is my health data uploaded anywhere?
No — all 7 calculators run entirely in your browser. Weight, blood pressure readings, lab values, and cycle dates you enter are never sent to a server.
Do these tools use Indian or Asian-specific health standards?
Where they differ from Western defaults, yes — the BMI Calculator uses the Asian-specific normal range (18.5–22.9) alongside the WHO standard, since Asian populations tend to have higher body fat at lower BMIs.
Are these tools free with no account required?
Yes — all 7 are free and unlimited, with no login required to use them.
