Hey Product Hunt 👋
I built CalcGoose because I kept running into small calculation problems that were surprisingly annoying to solve.
How much paint do I need? How many tiles will cover a room? How much power will a device use? How much material do I need for a project?
There are plenty of calculators online, but I wanted something focused on practical calculations that people actually need in everyday life.
CalcGoose currently has 37 free calculators covering things like home projects, power usage, pets, crafts, and other everyday calculations.
The goal is pretty simple: enter your numbers, get the answer, and understand how the calculation works.
Would love to hear which calculator you find useful, and especially what calculator you think I should add next.
