Now, I think the app needs a 'quit now' button, which would be quite useful if you use the back key to return to the previous screen (currently, the quickest way would be to use the '<' button and then the back key).

Also, not sure if intentional, but not all word definition data is present in the dictionary. Check 'reply' on en.wiktionary, first verb definition contains three example phrases which are missing (and were already present during last update).

And finally, your 'auto redirect' for 'inflected form' is quite useful saving us a click, but it does not help if you want to know which inflection it is. Using the 'reply' example, if I search 'replied', it automatically redirects to 'reply' (probably because there is only one link possible under 'replied'), and I can't know it which verbe tense it is (which is very useful for Romance languages like French os Spanish). I'd suggest two possible implementations: put the inflection info ('simple past tense and past participle of reply') as the first section on 'reply', before pronunciation; or add a configuration to disable auto-redirect upon inflection. The former would be way better, if possible.

Kind regards.
