This is an insane piece of software

I derive massive amounts of utility from this piece of suffered. I would recommend this for anybody that understands the value of modeling their life or any numbers in their life. Purchase this right now.

In app purchases?!?

martin023

I just updated hoping it would fixed the crashing and cursor bugs, but am slightly annoyed with the “optional” in app purchases (which don’t add any features) in the form of multiple ads on the file list. I have paid for the app and never really used it yet due to bugs, and they now want me to pay extra for no reason? I really have high hopes for this app and might be inclined to make that donation if the bugs are gone and the request is less obtrusive. Fine, show it in the settings and/or maybe ask for it once in a blue moon. Don’t put it as both an icon in the file list as well as a banner that makes the file list smaller.

A welcome (and useful) update!

Great update, lots of added utility! I respect the presence of a polite request for support of development and I actually didn't notice the request in the document list until I actually looked for it. I've seen a couple apps go the route of the optional support and I think it's a good idea. If I may be so bold, however, I would offer some sort of "perk" for supporters. I defer to the developer's good judgement to decide what that might be. Great work!

What an app!

Great calculator mixed with a Markdown text editor?!? Can life get any better? Honestly though, I've been using this app since it came out for the Mac and iOS, and it's just fabulous. I happily paid for both, but I completely understand the developer's need to make money and try this new approach. I'm just glad that it's still in active development. Now having graphs on the iPhone is great, and I LOVE the dark mode! The holy grail would be a way to handle tabular data in a multi markdown table!

Obnoxious 'donate' pop ups

WhyTheNickGuys?

The creators call it a voluntary donation, but I have never seen an app that forces even half as many "would you like to give us money?" pop ups while using it. What's worse is it disrupts your workflow as you can only make the pop up go away by specifically pressing the small "done" button on it.

Pretty good

Great concept. A few bugs but it mostly works well.

Best calculator app for math people.

If you are used to using a text editor, with the tab key and a monospace font, to keep track of things, this app is right up your alley. Stripped down and very powerful, this is exactly what I've been waiting for. I'm sure to tell my friends about it, and I don't mind the pop-ups at all. I wish all app developers would use a donate model. They could actually make a sustainable living that way. Cheers to the developer! I salute you.

Great features

This calculator has the most features out of all that I've looked into. It may look unappealing for someone because it looks like coding, but the documentation explains the syntax very well.

Wanted to love it, but implementation disappoints

I love the idea and design of this app. Combining Markdown and Mathematica/Wolfram Alpha presses all the right buttons for me. As soon as I read the app description, I needed it in my life. I was ready to donate before even downloading it. However, once I downloaded the app, I found it... lacking. The idea is great, but the app is buggy/"quirky". I find myself fighting with the interface, tapping on something over and over to get it to register the right action. The Markdown syntax extensions for doing calculations sounds great, but the app makes it hard to enter the correct equations, and get the desired result. Even the built-in example notebooks, which should showcase the app's features, don't completely work (one notebook, for instance, uses an undefined variable, causing it to fail to run). Overall, the quirks and bugs make the app more frustrating to use than not. For now, I'm sticking with Tydlig for interactive, explanatory calculations, and will copy+paste results into my Markdown editor if I need to write up text.

No longer usable on iOS 7

Despite the fact that under "Compatibility" it is listed that the app supports iOS 7, it no longer works on it. Upon opening, the app is unresponsive. Either none of the controls/items are tappable on the screen, or the app simply crashes at startup. Deleted, reinstalled. Same issue. This app used to work. iOS 7.1.2 / iPad 3
