This app is broken

I was needed exactly this! This app have a big variety of words, and a dictionary and translate acopled indo this. 私は研究を頑張る!

Response from developer

I'm glad you find this useful for your Japanese studies! Feel free to reach out if you want a promo code to try out all the premium features (if you're not already using premium).

Fascinating!

This app definitely lessens the waste of paper! But I found I was focusing more on trying to get the translation correct instead of writing! Well-developed regardless!! The Word Bank widget seems right up my alley for an everyday review of words I tend to forget, so I’ll absolutely be trying this new feature!

Response from developer

Thanks for your feedback. I find an effective way to use the translator is to only translate when you are not sure if your sentence is structured correctly rather than at the end of every sentence. I’m glad you like the widget, it took a lot of effort to work out how to implement them. But now that I have figured it out, I look forward to creating more. 🙂

great little app for writing in japanese!

i've been using this app a lot during my language exchanges, and i have to say its quite the lifesaver!! the grammar tab is really helpful for when you don't know how to formulate something.

Don’t Waste Your Time

Fancy design but that’s about all it has going for it. Ads are everywhere which I normally would be fine with but every useful feature of the app is paywalled. The paywall, of course, is also subscription base with the lifetime purchase being $25, a ridiculous value. I can’t even use the app to decide whether or not it’s worth $25, I get berated by a pop up telling me I need to spend $25 to even see what else is in the app.

I honestly never leave reviews but this was so appalling I had to. I understand the app is in a niche market but there are other ways to monetize your app.

EDIT:

Received an email from developer stating that they could provide a code to test out the app for a limited time by checking out their Twitter. Upon looking at their Twitter, I see a post by them calling me an entitled scum, how I don’t deserve to use their app, and soliciting people to report my review. Not a great look.

As you can’t even scroll down on some tabs of the app without being told to cough up some cash I’m not sure how the developer expects someone to buy their app without even being able to access 75% of it. I hope everyone that looks at this app sincerely reconsiders their choice and looks elsewhere.
