Twitterrific 6 launched this week. I’ve used their apps on iPhone, iPad & Mac since, well, forever and I’ve never truly thought about the cost. Until this week. Their new business model made me sit back and think about just how much I‘ve spent on their apps over the years and I realised it simply wasn’t enough. Great software costs and users should pay for it, no questions asked. That’s why I immediately signed up for @Twitterrific ’s annual plan and if you use a Twitter you should too.
