I wish I could rate this as 3.5 stars as I do see potential in this app. I love the design and convenience of it except for the fact that you can't download or save calculation notes. The lack of ability to have multiple calculation notes is disappointing. Also, it would be helpful to know what the premium tier benefits are before purchasing $6.50 for it. That's quite high price to pay for without knowing how that would benefit me besides helping in motivating you to keep improving this app.

Although the concept isn't new but this app is ad free so that's nice. It's very basic at this point & there are a lot of rooms for improvements. One issue I've found is it can't detect variable names with 2 or more words, so not very useful for my lists. On top of that I've to write all the variables again for expression, it'd be nice if it detected variable names & a tap on that would auto write on screen. And there has to be spare napkins (pages) as I won't just have one list to calculate.

A nice concept. The visual simplicity with the bold letters and a nice contrasting color is a plus plus. There are some points that could change for the better, however: having a simple (and maybe scrollable) widget to review your notes without having to open the app, and a page system with the infinite length per page, would be a really nice addition.
