Based on three separate vocabulary lists chosen by tab. It would have been better to have had definitions from the lexicons (Abbott-Smith, Strong, Liddell and Scott) displayed side by side, with a blank where the word doesn't occur, but the app is not that sophisticated. In fact, I got (on my Tab S4) the usual error messages (not optimized, designed for older version of Android) plus 'keeps stopping' (it hasn't). But for 89 pence it is cheap and, despite its shortcomings, quite useful.
the app does not open, it closes immediately
Very, very good indeed. Thank You a lot for Your so nice work.
The very first thing I noticed was that the letter episilon was barely visible on my Moto E screen (whereas other letters did not have this problem). I aasume this will occur on other smartphones using this particular app.This severely spoils the overall presentation and I suspect, will have a detrimental effect on using this app,
