A (Laurens) Hamilton fan
I downloaded this app like 2 minutes ago tbh but i have some questions: 1: is there like a premium that you have to pay for? Because I read all the reviews (i like reading reviews for some reason) and some of them complained about premium and I downloaded it expecting to see premium or something but it just said you are already premium so I'm confused on that, 2: the words/lessons, how is words like legend, amend, resign, etc in the last/hardest(????) lesson and words like qualify, abandon, oath, etc in the first/easiest(????) so I'm really confused

Data tracking

(: ME :)
Sketchy they want to track you across the different apps and websites you use: your user id, device id, usage data, and diagnostics. Instant delete. Edit: don’t believe their response, they would not be required to ask for consent if they didn’t track your data across services owned by other companies. Edit again: the person responding to reviews clearly doesn’t understand data tracking across apps and websites from other companies, sketchy when your app is doing it and it’s literally disclosed on your product page ha

Developer Response
Hello, thanks for the review. Allowing tracking doesn't mean the app can access all the data on your phone you have. It means the app can identify you ONLY in 504 app during the usage of the app. It helps us to show you the best content.Edit: Hello again. No mobile application can see the data of another mobile application. This is not possible with Apple products. This applies both to us and to other mobile apps.

English Audio Reading French Words Not Good

I set up the app to ostensibly teach me intermediate-level French vocabulary. The French words appeared in individual cards with French synonyms and example sentences. All fine so far. But when I pressed the audio pronunciation button next to the French vocab words, the built-in text-to-speech reader was an English voice which wrecked the pronunciation of the French words. This made the app essentially useless for my purposes. Unfortunate to say the least.

We keep the app updated to provide you with the best user experience!
