I didn't note them all down, but the ones I tried were shoving market statistics in my face and usually multipurpose for XMR, BTC and other things. All I want is to create or restore a wallet, send, receive, see a transaction history and optionally have a contacts book. This other wanna-be stock market stuff is not what I am here for... I mean, most of the fiat apps I see don't include conversion rates in their main screen when you open the app. x) The one I am currently testing is StackDuo. BTC, Monero, simple and nice. Will give Cake and moneroju a try though, doesn't hurt to try things out. :)

Manerujo is what you want. I agree simple uncomplicated design is a great heuristic. Cake is great for exchanging between btc and xmr, but for xmr only on mobile, manerujo.
