Tydlig Calculator Is Like Scrawling Numbers On Paper, Only Smarter




You know how when you’re working with numbers on paper, and you draw a line from the result of one equation to kind of “link” the result to the beginnings of another? Like maybe you’re planning a New Year’s Eve party and you tot up the cost of drinks in one section, the fake mustaches in another, and the overall cost in yet another?

Well, with Tydlig you can do that with your iPad and iPhone. And even better, the linked numbers get updated in any linked equations.

The app is so simple that the most confusing part of it is probably the name. To use it, you just tap in your additions, subtractions and multiplications on the familiar keypad in the bottom corner of the screen. You math is shown on the big canvas, which works just like a sheet of paper, letting you cram all kinds of formulas onto the page.

That’s fairly neat, especially as you can just drag number sand whole equations around the page. But even neater is that is the ability to drag a result from the end of one formula and use it as a component of another. The linked sections are connected by lines, and moving them really is as easy as tapping and dragging.

You can also drag the parts of the equation that sit before the “equals” sign, but in this case you’re actually moving them around, not linking them.

Many more complex functions are supported with an extended keyboard section, and you can also do some magical stuff with graphs. I didn’t test that though, as when we got to the graphs part in my A Level mathematics class I had almost literally no clue what was going on (the rest of my math was actually pretty good). Maybe if I’d had Tydlig and an iPad back in the late 80s I would have done better. Actually, if I’d owned an iPad in the 1980s I probably would have just left school and… I dunno. Worked on my to-do list workflow or something.

Tydlig is $5, and universal.

    I would have loved this in high school. Don’t get me wrong, I was useless at maths, but this is a great tool to teach since you can show students the “real thing”. This looks much better than doing graphs on some Texas Instruments calculator like we did.
