TOTALLY USELESS APP!! (1) It's NOT able to detect many of the local Dubai and Abu Dhabi telemarketing numbers. I doubt if this is made for UAE. (2) App has got no FREE version like Truecaller. Why do I need to pay for something that is of no use? (3) The process to mark a number as spam is lengthy. Plus, there is only one language field. If some names are already added in Arabic, I've to remove it to update the English name. These guys must learn from Truecaller.

After your free trial, this app is utterly useless, unless you want to subscribe for $13/month. And the trial is over & gone in 3 days (!) ... that's so quick I never even got the chance to try it, not that I really care all that much. If I needed this service that badly I would've already had one for the same price or way less from one of the many companies with good reps that are all over the place online.

Do not purchase their premium plans. It just a scam, you may think that what you are looking for is there but it isn't. I was looking for a contact number and it showed me one result which was precise but upon purchasing the premium plan to unlock the search results, it turns out the number does not exist on their app. What a waste of money. Not to mention they give you limited searches even after paying for it.
