It's a good idea to play with. I've been using Streak, which merges CRM with gmail inbox. Google's own task integration (as with Apple's, Yahoo, et al) have been poor.

But I agree with previous commenters that a speculative mobile app is unsuitable for kickstarter. I wouldn't be surprised if the new rules issued to prevent speculative hardware projects were eventually expanded to include things like mobile apps, but in any case it's a marketplace -- others with the capability to fund are free to disagree, and if enough do it will get funded. What's to complain about?
