## What is Equa?

Equa puts 65 accurate calculators and converters in one fast, modern app. No ads, no subscriptions, no sign-up and no internet needed.

NO ADS. EVER. Other calculator apps interrupt you with full-screen ads in the middle of a sum, or push you into a subscription. Equa has neither. Every tool is free and every result stays on your phone.

SMART NOTES Write math the way you think, and every line answers itself as you type: • "Rent: 1200", "groceries 340", then "total" for a running sum • "dinner 86 + 18%" for tips and tax, "20% of 640" for discounts • "5 kg to lb", "30 c in f", "1.5 hours in min" for instant unit conversion • Name values ("rate = 5") and reuse them, or use "prev" for the last answer • Tap any answer to copy it

ANSWERS RIGHT IN SEARCH Type "12*8" or "5 km in miles" into the home search bar and see the answer instantly. Tap it to save it to Smart Notes.
