I have doubt about this sentence.

Help improve Android Studio

I think it should be "Help to improve", because "improve" is a verb.

  • Is this grammatical correct?
    • If so, why is it correct?
    • If not so, why is it used this?

I tried to search about it, but I could not found it.

Biber et al (1999) make this statement: "AmE has an especially strong preference for the pattern verb + bare infinitives although the bare infinitive is more common than the to-infinitive in both varieties."

McEnery and Xiao (2005) relate this specifically to the verb "help".

So, according to their paper, "help" is much more prevalent than "help to", especially in American English. The actual percentages they found were, for American English, 79.5% : 20.5%, and for British English, 52.1% : 47.9%. (These percentages have been calculated from the raw figures given in figure 2 of their paper, p.164).

So, for American English, "help improve" is strongly preferred, and for British English you can virtually take your pick!
