Full disclosure: I’m an OmniFocus obsessive (nee user) and I’ve said before that it would take primacord explosive wrapped around my waist to get me to move away from it.
But then, I was pretty addicted to Appigo’s To Do app before finding OmniFocus so I can be moved. More, OmniFocus isn’t cheap. Actually, I think it is ridiculously cheap given how much use I get out of it and how enormously it has helped me but if you buy it and it just doesn’t do it for you, then it’s expensive. There are three OmniFocus versions (iPhone, iPad and Mac) and I spent £80 ($130 US) on all three.
Whereas SlydooTasks is 69p or 99c US. It’s too soon to say that it’s being recommended to me but I am hearing about it and the thing that keeps being said is that it is particularly good at filtering your tasks: letting you see the wood for the trees.
Before you spend that whole 69p and, more significantly, the time that it will take you to explore a new app and decide if it’s the one for you, take a look at a YouTube video by the developer that walks through it all: http://youtu.be/g7wJJhc5sk0
And if you then fancy it, SlydooTasks is in the iTunes App Store (UK link, US link).
