After watching the preview video, I immediately took advantage of the sale (since there's a refund if needed within 3 days for any reason) and I've gotten a good feel for the app and whether it will fit with my workflow. I love that I'll own this forever for one price, that's so rare these days!
The app has been running smooth for me besides when I tried deleting pictures I put in one field. The app crashed. Notified Noa and he said that it would be fixed soon.
Overall it's hard to tell what each pod is meant to do without looking at the guide, but I'm figuring it out slowly. There's also an occasional graphical issue that others have pointed out, but definitely useable and sure to improve in the future.
I'm really looking forward to the iOS app and syncing. That will help Pi fit into my workflow much better. For now I'm stuck saving things I need to access somewhere else because I'm afraid I'll need it and not have it, but it's unbeatable for quick notes and things like writing this review! Things I think I'll need elsewhere can be exported for the most part.
All in all, I feel there's a lot of good things coming for this app. Noa has been very responsive to emails and I take that as a good sign.
At first I played and I ran into a few issues. But then I emailed the developer and he went to town cleaning it up. This is a super elegant and tasteful product, which more apps were like this. I HAVE TO SAY MORE. So when I wrote my first review, I was drowning in work and things to do and I was avoiding work and looking for a todo app to feel like I was at least organizing myself and not completely blowing off work, like I am doing now. Anyway, this app is super awesome - I love how simple and tight and useful little menu item apps can be and they are accessible, especially the feature to type and write stuff from the menubar being open and from the web. So can I live without it being perfect from the help files? Sure, really, who reads that stuff anyway and fi you can't figure it out, then should you really be using a computer? Having a collection of contact circles is useful too, so I don't have to clutter my contacts with stuff to then hide on my phone. Anyway, buy this now, this developer has a calling, he is doing it, now he needs to be supported.
