I thought people used calculators for "big" things.

Loans.
Taxes.
Mortgages.
Then I realized we use them for tiny things all the time too.
Tips.
Percentages.
Splitting bills.
Figuring out discounts.

Those little problems are actually what inspired me to build CalcDeep.

@edwardindiedev 步入正轨的开始👍，我的站点上线2个月了，现在还没有任何流量

Small reminder from building software:

The features users never see often take the longest.

A tiny calculator can involve:

→ edge cases
→ validation
→ mobile layouts
→ testing different scenarios
Simple on the outside.
Complicated underneath.

@Edison_aware @10xmylife 国内的钱难赚呐

Splitting a bill shouldn't require mental math. 😅

Dinner with friends?

18% tip?

Splitting the check?

It shouldn't take 5 minutes of calculator app hopping.

So I built a simple Tip Calculator for those everyday moments.

I thought building a calculator website would be easy.

Enter numbers.
Click a button.
Get an answer.
Simple, right?
Then I discovered:

Time zones exist.
Rounding exists.
Mobile Safari exists. 😂

Building simple tools is harder than it looks.

Most people think BMI tells you if you're "healthy."

It doesn't.

BMI is simply a quick screening tool based on height and weight.

It's useful—but it's not the whole picture.

Curious where you fall?

@miradreaamy 28. (9×12, 8×11... 4×7) Made a calculator site but still do these in my head.

@liferacerza 8? (Wait, let me double-check... x=5? No, 8x=40 → x=5 Got there without a calculator... barely. Btw this is exactly why I built CalcDeep — for when my mental math fails me.😀

Hi, I'm Aelin 👋

Professional overthinker of tips, taxes & loan payments.

I got tired of opening five different websites just to calculate something simple, so I started building CalcDeep.

Free calculators for everyday life.
