Where is the vix?

I bought the ap today. I really like how it graphs up strategies. But now that I have made the purchase, it crashes. Plus, I can't add new strategies. Please fix this. I would have contacted customer support directly instead of posting here, but there is no button for that on the ap.

Good graphics, but seems just a start

I really want to like this app, but in truth it seems like a good start and needs work
- will retrieve option chains, you
don't have to manually enter data
- nice looking profit/loss graphs

- Once a position is entered, you
Can't edit it, other than deleting.
(E.g set the price to reflect the
price you have actually got )
- Graph has 5 ticks between any
Two values - this is AWKWARD.
If you have a range (say) 10..20
Than 5 ticks = 6 intervals, so
The ticks represent 10/6=$1.67
- Graph does not show an up-to-
Date vertical line at the current
Price of the underlying

Puzzle: I see an offer to get a 'pro' version for $4.99 - great. What IS that version doing better?

Missing (at least)
1. Editing positions
2. Saving/retrieving positions
3. Dynamic info on graphs on the
Point you touch
4. What-if handling for changing
Date and volatility assumptions

I actually have lots more ideas on things to improve it but there seems to be no way to contact the author

A great start, .... but

As others have already stated in their reviews, the developer doesn’t allow you to edit the price.
- Graphics
- Easy interface
- Multiple strategies
- no manual editing option
- only one strategy allowed in free version
- upgrade to pro only gives additional strategies, but no other additions
- limited data
