Don't know how practical this app is, but it is sure fun to play with and for that reason it gets five stars. Runs great on the air 2.

Use it all the time for notes and calculations. Best calculator app.

The app looks pretty bad on an iPhone 6+. Dropbox sync sees all my markdown and unimportant files, but doesn't see Calca files. Totally useless

Fun to work out solutions without having to launch excel and crest complex spreadsheets. Easy to learn. Needs to be updated though.

This WAS a 5-star app. But in latest version document jumps up and down all the time while editing. So it is impossible to use and also incredibly frustrating that a single editor bug renders such a great app useless.

Possibilities seem to be endless for this app... If only I could get it to display a different number of decimal places!

Easily one of my favorite and most useful apps. Unfortunately I have been relegated to mostly using this on my mac these days because it doesn't work in landscape with the on screen or bluetooth keyboards. PLEASE Fix this so I can go back to recommending this and making it a 4-5 star app again. For those that like it, seems it works in portrait mode now... doesn't help if you have a case/keyboard that has you using landscape most of the time... but at least it works.

Hate this app. The screen jumps up and down when I type. Truly regret purchase because of this problem.

When you need to think some sort of calculation through this is an amazing app. It is like having a live back of the envelope. Really a new way of helping one think. If had landscape mode and was easier to insert text in a line and to add line breaks (maybe some arrow keys?) this world be a 5 star app.
