I would like to point out that evercoin has a great app which is absolutely amazing for exchanging one crypto to another. In the apple app store it has a 4.5 star rating with close to 2500 reviews from happy people. I just used it myself for the first time and it works awesome. It has IOS app and Android.
This is for people that want to use their ethereum or bitcoin to quickly buy ripple or any similar situation. Dash and waves can also be exchanged for with the click of a few buttons. The fee is definitely not that bad either. It is comparable to exchange fees after you have to send eth over, get a maker/taker fee, plus the withdraw fee and gas once again to send your tokens out of the exchange... So yeah it is actually cheaper to convert this way than with an exchange unless you already have eth or btc in an exchange, but if you had that why would you even be reading this!

IMO, shapeshifter already has support for mobile devices so it really doesn't matter that much whether they've got an app for their service or not. After all, the process is already very very easy already.
Shapeshift is a lot more trusted, but nobody says that you can't use ever coin.
Their site looks good, just that shapeshifter has been around longer I think and resolves issues quickly and has a track record of doing so.
