There are plenty of exchange apps, both for Android and iOS.
At the moment I've tested 3 most common apps:
- Binance - sometimes ok, but not for the first time I somehow can't go through KYC via this app. Notifications don't work correctly, etc.
- Coinbase - was ok even with slow support, but after they increased their fees to 0.5%... Well, sorry, not going to use it.
- Changelly - it's new, I don't know if it's stable and well-working, and there are not enough reviews, but I was satisfied with the web version though
My question is: does anyone use exchange apps? If so, which ones? If not - why not? Share your experience, please.
I'd have to give the in app experience to coinbase on this one. They have the most mature app out of all of them, with the most user friendly (or at least aesthetically pleasing) GUI in my opinion.
However, that in no way means that their service is any good. If you just look around the forum briefly you'll find a ton of complaints in regards to coinbase, especially in terms of their customer support which has been historically been unresponsive. Despite Brian Armstrong's promises, this has never really been fixed since coinbase's inception. Their fees are also high due to them accepting CC for purchasing BTC. So I strongly do not recommend you use Coinbase, no matter how good their UI looks, until their fix their fundamental problems.
I think that your best pick is Binance. Like hamdi said I don't see a reason in using an app exclusively for an exchange, you're already going to be limited from the get-go on functionality. As to your KYC problems, why not just submit KYC through the web page and sign into the app once you're verified?
