That was not your mistake, I only added it after reading your initial comment!

Thanks for the detailed response, I understand what you mean by not wanting to give your credit card info out. I used to not have that requirement and then was encouraged to do so by someone I respect in business. The logic was that it is a very saturated market and people are prone to trying lots of options without paying them much attention whereas if you've given over your CC details you're more likely to use the trial period fully and therefore get benefits from the app.

I might switch to freemium at some point soon and see how that works for people. Given it's a side project I'm not sure why I'm so concerned about maximising revenue as that's not really the goal!

Thanks for the advice, I hope that you end up using Tatask from here on out. Also if you have an iPhone, the app is in review currently and should be released very soon.
