Right consequence, but wrong reason: the iOS apps only support context mode perspectives, whether you own the Mac app or not. If you don't own the Mac app, you need the assistance of someone who has it unless you are very good at tinkering. I did it once, just to prove to myself that I could, but it isn't practical for most. Certainly, the value of your time involved in figuring out how to do it and then doing it would far exceed the cost of the Mac app, and probably a used Mac mini!
I have a few perspectives I use frequently on the iPad:
remaining actions, grouped and sorted by date added
completed actions, grouped and sorted by date completed
remaining actions, grouped and sorted by date changed
these allow me to either see what I've been working on lately, or find what I accidentally changed.
I have a few perspectives that essentially collate a number of contexts together, because I use a hierarchical context structure. For example, I've got a section of the tree for grocery shopping:
Errands: Grocery store
Errands: Grocery store: Sigona's
Errands: Grocery store: Trader Joe's
Stuff I prefer or can only buy at Trader Joe's will go in the last one, stuff I can buy anywhere goes in the first one. If I'm at a grocery store, I pull up this perspective, which groups by context, and I'll do all the stuff specific to that store, and anything from the top-level context that seems appropriate. I can collapse or expand the groups for other stores on the fly with the little triangles at the upper right hand corner of each group.
If your work divides neatly into some big categories (like work vs. personal), it may be advantageous to create top-level folders for each category, filing projects accordingly. Then you can make a set of perspectives that focus on each category folder, displaying the results in context mode, probably grouped by project. Armed with this, you can view only your work-related tasks, or your personal tasks, etc.
