Wolfram Cloud

I have given bad reviews in the past to this app. Since the external keyboard issue was fixed I am now happy with it. I can actually use the app for useful work. I wish the interface were more like the standard front end notebook interface, e.g., you can not do 2-dimensional input, or use control characters for Greek letters, subscripts, superscripts, etc. Also, I wish it were easier to move data files between Wolfram Cloud and the iPad. Sometimes the latency from the server is pretty high. Otherwise, I can now see the possibility of ditching my laptop and just using my iPad Pro. Thank you to the Wolfram developers, this is great. Followup (November 26, 2022) There has been no attention paid to this app, as far as I can tell from the version I reviewed above. Perhaps, Wolfram believe the app has been superseded by Wolfram Online. It has not. Wolfram Online is buggy on mobile devices, like the iPad Pro, and it’s interface design is more Web 1.0 or whatever the current standard is. The app is actually better, but lacks so much versatility. Now that the iPad Pro has the M2 processor there is no reason for such poor performance, even in a client server model.

My use case is being a university student. I got this app in hopes that I could edit documents on iOS without needing to use my Desktop. In that aspect, yes you can create and edit .nb files from *the cloud*. Now the negative: Why can I not use documents I downloaded, and why can I only have access to a file for 60 days? I am using Mathematica (full version) via being a university student, yet I need to pay extra for the cloud which is essentially necessary to use the iOS version? Again, 2 stars because my complaint comes from the business practice of charging the university for licenses for students, *and* making students pay, essentially, so they can use it on mobile operating systems. Either allow importing and exporting of documents via local storage, or give people with a paid license of Mathematica the ability to access cloud files for until the license expires. Otherwise, this app is, essentially, restricted to quick documents you don’t want to save (ie for homework).

Although the system runs on the Wolfram Cloud and online Mathematica instead of local computer hardware, the software is quite beneficial. From my usage of the cloud and local Mathematica, I can attest that the “mobile” version of Mathematica can handle Algebra I, Algebra II, Pre-Calculus, Calculus I, Calculus II, and Differential Equations. However, although the online version of Mathematica can do partial differentiation and multiple integrals, as required in Calculus III, the online version lacks in the graphing of planes in 3 dimensions - specifically rotating them. Nonetheless, I have not seen an app that one can pull out their phone and easily solve a differential equation: DSolve[y’’[x] + y[x] == 0, y[x], x]. The function of this software is truly up to the user - where it might be helpful to some and not functional for others. However for the high school student or undergraduate in college, this is quite an investment in your education.
