From the start I tried to translate a simple sentence from English to Arabic. The translation was correct, however when I tried to listen to the audio, it said there was no WiFi connection, or cellular data was not enabled, neither of which was true. So I switched to the offline translation and tried to listen to the audio, and instead of hearing the translation, the program crashed and would not reopen. Also, there are no vowel markings, which can be a problem for non native speakers. For example, if you were to search a simple verb like نَزَلَ, you would not know if the definition given is for نَزَلَ or نَزَّلَ. This app should be free, and even then, I'm not sure if it would be worth downloading. Aside from the crashing, it needs some serious upgrades. I would save your money and go for Al-Mawrid, which is the best dictionary I've used so far. It's a bit pricey, but still cheaper than this app.
