Version 1 of Time Out was available completely free, with a suggested donation to help support development.
Version 2 uses an unusual pricing model: it is still free, but you can become a "supporter".
If you wish, you can download and use the basic features (roughly equivalent to version 1) at no cost, forever. You don't have to buy up-front, and the app won't stop working after 14 or 30 days like traditional apps (like Simon and Caboodle, for example). I want everyone to be able to have a great break reminder tool, even if you can't afford to pay anything.
But certain new features can only be tried for an hour at a time, then they revert. These features can be tried as often as you like, and are marked by a heart icon that animates in next to the control when you hover over it. You can click the icon to display a popover with more information.
When you use one of these features, the icon remains visible and red, and the popover automatically appears for the first one you use, to make it more intuitive that you can click the icon to find out about it. Also, the heart icon next to the "Support Time Out" item in the sidebar starts to "beat", and a countdown message appears below it, indicating how long until the features revert.
To keep these features available permanently, you can become a supporter. This is a small payment that helps fund development of the app, and shows your appreciation of how it makes your life better. The advanced features will remain available as a reward for your support.
There are three supporter options available: 3 months, 6 months and 12 months; basically one dollar per month, with one month free for 6-month supporters, or two months free for 12-month supporters.
Although there is a time limit, this is not a subscription, and the features won't stop working when it expires. These are one-time payments, and they do not automatically renew. When the supporter period expires, you can continue using all of the features you had as a supporter, without paying anything more. But if you are still finding Time Out useful, you are welcome and encouraged to renew your support.
Thank you very much to everyone who has become a supporter in the couple of weeks since 2.0 was released. It's very gratifying to have so much positive feedback and encouragement. This pricing model is very much an experiment, but so far it is working very well, with a large proportion of people opting for the 12-month supporter level as a way to show how much they appreciate the app and the improvements in version 2. I'll follow up later about how it's going, and compare the direct and Mac App Store editions.
