Simple Calculator brings together everything you need for daily calculations in one clean, easy-to-use app. Whether you're a student solving equations, a professional managing finances, or just someone who needs to split a bill, this app has the right tool ready to go. What You Can Do Start with the basic calculator for everyday arithmetic — addition, subtraction, multiplication, and division — with live results shown as you type. When you need more power, switch to the scientific calculator for trigonometry (sin, cos, tan), logarithms (log, ln), exponents, square roots, factorials, and π, with both radian and degree modes. Every calculation is saved to your history, so you can revisit and reuse past results anytime. Financial Tools Built In Calculate GST and VAT on any amount, with options for adding or removing tax and support for both Intra-State and Inter-State rates. Plan loans with the EMI calculator to see your monthly payments and total interest. Estimate SIP investment returns, project your savings growth, work out salary breakdowns, or convert between world currencies. Quickly figure out discounts while shopping or split tips at restaurants. Health And Daily Utilities Track your Body Mass Index with the BMI calculator, find your exact age down to the minute, calculate percentages and percentage changes, and convert between units of length, weight, temperature, area, volume, time, and speed. Make It Your Own Choose between Light, Dark, or System Default themes.
