I've used this service for a long time, and really appreciate it. Unfortunately, the app has recently had an insane amount of ads added to it - nearly half the screen is taken up with them, and sometimes full screen ads that are difficult to close are shown. I understand that it's a free app and that ads are necessary, but there has to be a reasonable limit. At this point I'd rather not use the service, in favour of others like weblio.

This is great but would be greatest if I could look them up directly like a pop up or jump onto the definition on this on androids chrome. It's a bit a hassle to manually move to this apps and paste a word to do it. Apart from that this is most reliable relevant japanese-englsh dictionary you can find on the internet I assure.

As an English related business worker, Eijiro Pro has been my inseparable companion for many years. I really appreciate its vast and various entries. However, you have to bear in mind is that this this is an online open dictionary and you shouldn't trust too much it's contents just like Wikipedia.
