My favorite now is DAWQ. It almost sounds too good to be true: all-platform wallet, and optional investing done for you, with small amounts taken from your wallet but ballooned together for max effect.
I really hope this is achievable and will be a working project, already signed up for the pre-ICO. Have been posting in their thread and asking some questions and answer is always insanely fast and informative, so that gives me a good feeling about it.
This it the link to said thread:
