Hello! I would like to share you the calculator app I just released on google play. I developed it after being always kinda frustrated on the limitations of the pocket calculators. It is meant to greatly simply the calculation process, presenting a sheet where you can place multiple formulas, drag results to reuse them, define variables with any name, etc. A few pictures speak better than words! All details about the available functionalities is on the google play page. The free version comes without ads or limit of time, but has a limit in the number of formulas. So it is very usable I would love to have you try the app and let me know what you think about it!

Cool! Looks pretty good. I use Calculator on my iPad sometimes (Android version), and it's good, but sometimes it struggles to recognize certain symbols, and erasing things is a pain. But i think the way you've done it eliminates this issue.

Oh yeah MyScript Calculator has some pretty amazing character recognition! I actually experimented a similar app with a friend for a uni assignement. It would let you take a picture of formula and transcript it on screen. It would be cool to add this to Blocks Calculator, though I'm afraid in the amount of time I would need to put into it in order to make it work reliably Also, if the app works well I will get my hands into swift and bring it to the app store. Thanks for your comment!

I've already satisfied with the calculator on my smartphone. At least it can recognize that $\displaystyle e^{\pi\times{i}}$ is 1, unlike the socalled pocket scientific calculator which gives an error screen.
