Great app but needs work

I really like it but unfortunately to unlock all idioms you need to make a payment and who knows after an update of the app since there's no restore payment option. It would have been better if the full-version was released separately so that it would ease my mind in purchasing that.

Developer Response ,

I'm sorry for the problems..I created and run this app alone. If you want to reinstall the app just say yes to the purchase of the will remember you have already paid and won't charge you...if it does I will refund you

Very nice and useful app!

This app is very useful for people who are interested in languages and learning new terms. The meanings of idioms are illustrated in a fun and joyful way, and the meanings are very clear also. By combining both definitions, examples and pictures for illustrations, the app makes remembering terms even easier.

The UI is simple yet gracious, but the menu pane is not the same style with the main UI of the app, making it looks awkward.

Overall, the app works great, I just hope the UI will be improved.

Have to repurchase after every update

This app has to be purchased again after every update. So frustrating! The idiom illustrations are great, but they should choose ones that are more commonly used. I purchased this to use with middle schoolers, and many of the idiom descriptions are not appropriate for that age group.

Developer Response ,

This is simply not true... I had problems with one upgrade in 2017 and I refunded and replaced the app for everybody...since then it is working may ask you to repurchase the app if you want to reinstall it but it will NEVER charge you twice..if it does I will refund
