■ Finance (11)

Loan payment · Total interest · Take-home pay
Gross pay from net · Monthly-annual salary
Simple & compound interest · Savings & deposits · Savings goal
Investment return · Pension · Tax · Budget

Compare equal-payment and equal-principal loan schedules side by side.
Take-home pay shows your salary after the deductions you enter —
or work backward from the take-home pay you want to find the gross salary you need.


■ Home & Daily Life (8)

Sales tax · Discount · Tip · Split the bill · Utility bill split · HOA fee split
Moving cost · Rent comparison

Bill splitting divides the total per person down to the cent.


■ Currency & Travel (9)

Live exchange rate · Travel budget · Local cost of living
Rental car cost · Fuel economy · Gas cost · Baggage fee
Travel insurance · World time zones

Currency uses live rates (optional connection) and saves the last rate it fetched,
so you can still calculate offline using that last known rate.


■ Health (13)

BMI · BMR · Daily calorie burn · Body fat percentage · Waist-Hip Ratio
Time to reach goal weight · Exercise calories · Steps to calories
Water intake · Sleep duration · Heart rate · Blood pressure · Alcohol intake

BMI shows your body mass index alongside your weight category, and BMR
carries straight through to your estimated daily calorie burn.


■ Basic Math (9)

Percentage · Percent change · Average · Ratio · Exponent · Square root
Greatest common divisor · Prime factorization · Base conversion


■ Unit Conversion (19)

Length · Weight · Area · Volume · Temperature · Speed · Time · Angle · Pressure
Energy · Power · Data size · Network speed · Bits · Illuminance
Noise level · Concentration · Chemical amount · Conversion table

If you often convert centimeters to inches or kilograms to pounds,
save a conversion table and reuse it anytime.
