Sidetodo The Todo App For Mac
Okay after testing 2do, Omnifocus, Todoist, Pocket/Desktop Informant and Sunrise. I've decided to go with Sunrise. I like the iOS app and Mac App it gives a nice Today/Week view of my projects/times available (easy for telling clients), it connects to just about every major 3rd party app cal programs. 
Easy on the eyes (not overwhelming). I haven't tested Fantastical 2 yet since it was crash with OS X El Captian Beta. For my needs it wasn't about needing a 'todo' list but more of a time management (productivity) application. I can now easily see when i'll have 2-3hrs free to do personal stuff.
I maybe end up using Any.do for my todo list just because I like the daily remember it sends to sent up your day. Is there anyone using 2do in Apple Watch?
Best Todo App For Mac
The Mac App looks very similar to iOS version in terms of design, however it has a few tricks up its sleeve that make it stand out. You get the useful ‘Trash’ feature only on the Mac, which lets you view all the to-dos that you have previously deleted. Wunderlist is a simple todo list and task manager app that helps you get stuff done. Whether you’re sharing a grocery list with a loved one, working on a project, or planning a vacation, Wunderlist makes it easy to capture, share, and complete your todos. Track all your tasks easily and be productive. Access your tasks from your Mac Menubar.
Todo App For Windows
I have a problem with the app. Everything is fine on my iphone however the checklists can not be marked on Apple Watch. I see the checklist items on Apple Watch. I select each item to mark it as done. Then an approval or decline page comes.
But when I click to OK (left green button) button to make the item done, it makes the item done on Iphone, but the checklist item list stays same on Apple watch. There is 4 grocery items in one checklist. When I select any of them to make it done, it doesn't update checklist on apple Watch.
Did anyone experience this problem?
