The Althea project is an interesting one. I have not done much research into it yet, but its on my radar.
As for Keplr, I have not used the mobile version of it so I can't really help there. I do know the mobile app is only quite recent addition (in the last month or so) so its likely still buggy.
I have used Cosmostation as an alternative Mobile app, and it worked well for staking and basic functions. I stopped using it and shifted to the keplr browser for Osmosis functionality.
Thanks for the comment @r3dbeard

Althea is one I've been following for years now, it's looking pretty legit. I don't know much about Osmosis, but I do have Cosmostation, just haven't acquired any ATOM yet - now seems like a possible buying opportunity with capital appreciation + staking income at APY of ~14% for a double-whammy
