However, its next release is different.
Not only is 30/30 a free time management app, but according to president Bob Koon, he's experimenting with a new monetisation method too.
Quality time
30/30 works fairly simply in that you set up a series of timed slots so you can focus on, say completing a task in 30 minutes and then schedule 15 minutes of Facebook time.
You can set up multiple tasks in slots ranging from 1 to 60 minutes, and the in-app purchase system is similarly presented.
"The model is 'pay what you want'. I ask the customer that if they find 30/30 useful, that they consider supporting it," explains Koon.
"I also bypass the whole notion of unlocking content (there is nothing to unlock) and also waiting for receipts to verify with Apple as an anti-piracy measure. It's pointless to fake a purchase such as this."
Show your gratitude
There are three non-consumable IAP products.
$0.99 - Bundle of Thanks
$1.99 - Heap of Thanks
$2.99 - Boatload of Thanks
Koon says he spent some time coming up with the right descriptions, avoiding references to donations, which are limited to non-profit organisations under iTunes' terms.
30/30 is due to be released for iPhone and iPad on 7 June.
