OK so this is one more big titties h-anime to add to list of over a trillion (j/k) big titty h-animes heres is the plot as copied from what i wrote for the synopsis:
Masato saves a cat and as reward gets a smart phone with "ero-apps" which he uses on his sister, head of the school disciplinary committee, the half japanese/russian transfer student who is a pilot because the school has an airfield (for well "reasons") his childhoods friends, the student council president and various other students at his school.
anime has TWO episode each about 20-30 long no idea if there is a licensed dvd/blu-ray release coming; but i did find them on online subbed in english (won't mention site name since i'm not sure i can do that and not get a ban)
the episodes functions as "sketches" with each app having a different function based which girl is the focus of the "sketch" which means that the "plot" is mostly a "sex-romp" instead of a "romance" overall not bad if your into GIANT tits animes then give this one a watch :)
