Well this is... eerie. I just released Stictionary[1] on Friday. It is an offline, ad free, dictionary that remembers words you look up. It gives a word of the day and provides (admittedly underfeatured atm) flashcards to review your word lists. It includes optional syncing to keep your word lists across devices. I've been holding off posting about it while i complete the website[2]. Love to see someone else had such…
By the way, you may be aware but there's a typo in the iOS app in the "Your Words" tab when your list is empty.
> You can swipe words off your list later if [you] add a word you'd rather not see.
