Understand that Finandy now has tons of features (well done jobs), and it is no easy task for having a full featured mobile app for now. here I'd suggest:
a simple mobile app (not mobile browser friendly web) that can manage basic actions of Hooks and Trades:
  1. On/Off hooks (no creation hooks, just on/off)
  2. Close Trades (just close existing trades, no terminal needed)
  3. list of existing trades (users can check and be at ease that no crazy things happened while they are outside)
I think lots of users will be ok and grateful with this very 1st version of mobile apps, means they can at least not to worry something extremes happens, but they don't have a computer.
