Very simple questions

Why I made DTS-Calc, a small distance, time and pace calculator.

By Hafiz

I always wonder how long it'll take me to finish a run or a workout. Very simple questions.

What's my speed? What's my distance?

Sometimes I see someone's running time and wonder, what's their pace? What if I ran at their pace over my distance?

It's not that there are no apps for this. They exist, in huge numbers. But they look complex, too old school, or they're just plastered with ads.

So I acted.

I made DTS-Calc for what I need, and maybe for what you need too. I also added imperial units, though I've never needed them.

There's another mode, Multi Pace Mode. I'll talk about it in the next post, because the idea behind it is interesting.
