This has been the most frustrating app for studying Japanese I’ve come across. I bought the full version and don’t regret it, but wouldn’t recommend it. The app is riddled with errors that never get fixed like incorrect translations and superscript that doesn’t display correctly. No matter how often you report it, nothing gets fixed. Besides that, despite passing the JLPT, grammar and sentences in these levels don’t match the real tests. After passing N4, I still could barely understand most of what was in the N4 material here. Although I liked the idea, it’s just not an effective study app.
App support here - hello again! About your comment, now slightly updated from last month, it seems that you have been trying to report errors to us. Thank you so much! As mentioned before, the active email address is iphone(at)bunpo(dot)app (please place the words with the correct symbols where necessary). [As a reference, please see our previous reply as follows. -->]Thank you for your candid feedback. To contact us with your reports, please email us at iphone(at)bunpo(dot)app and we will happily take a look. We did check in N4 Chapter 2, in all exercises in lessons 1 and 2, and the only instance of 昨日 seemed correctly notated as きのう. If it appears as きに in your device, then please double check that the app is updated to the latest version. If some sentences feel overly complex, then we are happy to review them. Please send a screenshot to iphone(at)bunpo(dot)app and we can take a look. Thank you.
