We will need to try out the iPad version before paying and we'll want the discount. Also, 7-days is not enough to trial. We need at least 30 days. Also, if I was to try the iPhone version, I would want it not to expire until after I was able to trial the iPad version and when done, I'd want the discount. Your time limits are not long enough.

However, one solution is very simple. Don't release the iPhone version until the iPad version is ready to be released. Then we can test both for 30-days and then decide if we'd want to pay for it with the dicount.
