A couple of small bugs can make the app appear broken (see below), yet it's largely more capable than the popular and polished Textastic.The workarounds that keep it working for me:• When it appears to crash on launch, I'm able to get into it via the app switcher.• [UPDATE: This appears to be fixed in the 4 March 2018 update.) A file can appear almost entirely blank, showing nothing but its first line; momentarily rotating the device fixes this for me.The app's functions are more customizable and robust than those of Textastic. FTPOnTheGo Pro has simpler, less-confusing directory navigation than Textastic 5.3.1 on iPhone (where the file-transfer and local-files views can be readily mistaken for one another), and simple edits to a remote file needn't involve fussing with a local copy as Textastic requires. (Textastic also requires more care to make sure a file gets uploaded to the correct location—!)On the other hand, updates have been quite rare, while Textastic has smoother performance and a more pleasant editing environment, plus some support for VoiceOver.In version 4.4.2 my Dropbox connection isn't working.FTP On The Go PRO has a good FTP toolkit. If and when those bugs are fixed and it has a little more polish (better VoiceOver integration, more sharing options, etc.) I'll be happy to give it five stars.
