## Description

A calculator that handles units. 3kg+5m? Stopped. 60km/h × 2h = 120km. 100kcal ≈ 0.5 rice bowls. Numbers with meaning.

A new kind of calculator that takes units seriously.

Add kg, km/h, kcal to your numbers and just multiply or divide. 60 km/h × 2 h correctly gives you 120 km. 1 kWh ÷ 1 h = 1 kW works naturally too.

Trying to add unrelated units like 3 kg + 5 m? The app politely stops you and offers to switch to multiplication with one tap. You catch the mistake and move on instantly.

Results are shown in relatable scale: 100 kcal is "≈ 0.5 rice bowls", 4.7 GB is "≈ 1 DVD". Numbers regain their meaning.

Features
- Launches with the leading unit of the active category preselected (Mass → kg)
- 9 categories: Mass, Length, Time, Volume, Area, Temperature, Speed, Data, Energy
- SI base units + Celsius/Fahrenheit + binary data units (KiB, GiB)
- Imperial units (in, ft, yd, mi, lb, oz) and US cooking measures (gallon, fl oz, cup)

- Tap "No unit" to use it as a regular calculator
- Smart blocking of dimensionally invalid calculations
- Scale comparison cards beneath every result
- Available in 9 languages

"If you can't measure it, you can't understand it."
