Is there any mobile app wallet that can fit most or all altcoins? The best I have seen so far is Coinomi for android, which has many altcoins but still it doesn't have the altcoins I want like Neo, Monero, Lisk, IOTA, OmiseGO etc..

So do I have to download a seperate wallet just to keep the altcoin that I want?

I would prefer mobile wallet over desktop wallet as I trust mobile more
