5/5Satisfying since the day one
I think I have used the app and website since their first year. They have never stopped improving, and not only have they added great features along the way, but they also have enhanced every little detail you can think of. By far this is the best dictionary for Persian/Farsi you can find and rely on.

3/5Text translation error
I really like this app because it shows all the definitions, synonyms and antonyms and also has phrases and proverbs. Something that i loved about this app was the text translator but recently it has annoying errors claiming that I have reached the limit while I haven’t even used it in days. I tried making new accounts and switching them but it didn’t work I hope something be done about this because i need and use this app a lot

5/5Wonderful
This app is incredibly useful. So many times I’ve searched for words or expressions that other dictionaries couldn’t find, yet this app had them instantly. It’s been an amazing resource for learning and expanding my vocabulary. A huge thank you to the team behind this app for creating such a reliable and well-designed tool. Your hard work is truly appreciated. Keep up the fantastic work!

4/5Phonetics are great
I’m learning Farsi and this app is super helpful in providing the phonetics for the words. Not all words have phonetics though, so it would be nice if all of them had it. Also the ads got soooo annoying that I wanted to pay the .99 to remove them but since the app is all in Persian I had trouble finding how to pay. It would be nice if the app was in English to be able to navigate it better. Overall very helpful app!
